Looking for the best video compressor for Windows or Mac that lets you compress MP4, AVI, MKV, MOV, and more types of files effortlessly? Whether you are sharing a video recording with your friends via social media, freeing up the space on your phone, or sending a long MP4 video by mail, compressing the original video file with paid or free video compression software is a must.

With that in mind, I've collected the best paid and free video compression software for Windows and Mac computers as well as the best online video compressors for Chrome, Firefox, and other browsers. Some of them can even handle the compression of 8K/4K/1080P/HDR videos recorded by popular devices such as DJI, GoPro, DSLR, and iPhone from GBs to MBs at blazing fast speed, without visible picture quality loss.

To help you quickly find the best video compressor that meets your compression needs, I've run down some of the most standout features, video compression performance (with real test data), cons, and pros of each tool.

  • Can compress popular video and audio formats

Freemake Video Converter

Freemake Video Converter is one of the best free video compressor for Windows (earlier versions like Windows 7) and it used to be my favorite pick. However, it hasn't received any update since 2017. Many new but important features are missing in this phased-out video compression software.

Here I take some examples. It's hard to set a high video or audio compression ratio in Freemake Video Converter. H.265 and VP9 are not supported. It provides you with some presets, but only matches with iPhone 5, iPhone 4, and things before 2017. It doesn’t support adding customize watermark. However, it will put a big Freemake logo on the output file which can be removed by only upgrading to the premium account.

Features:

  • Compress videos by setting the output file size
  • Preset output profiles for Samsung, Nokia, and BlackBerry
  • Make photo slideshows. Add SRT/ ASS/SSA subtitles
  • Rip and burn home or unprotected DVDs

Pros:

  • Easy interface

Cons:

  • Mac users can't make utilization of Freemake Video Converter
  • Lack of preset for recent devices
  • Frequently crashes
  • The final video comes with a big Freemake watermark
  • HEVC, VP9, and many popular formats are absent
  • The anti-virus program reminds me Freemake Video Converter is bundled with malware

Overall rating:

Freemake Video Converter seems to have some incompatible issues when compressing ultra-high resolution videos. I tested 10 clips of 4K videos and 15 clips of 8K videos on it. (The testing videos come with length from 1:30min to 3min). Everytime, Freemake Video Converter got stuck when finished the process of 60% to 85%.

#3) VLC media player

  • Best free video compressor software that can play 4K large videos smoothly.
  • Can compressAVI, ASF, WMA, MP4, OGG, VOB, MP3, FLAC, and more.

VLC Video Compressor

Unbeknownst to some, the VLC media player is a cross-platform and multiple media player on Mac, Windows, and Linux that does more than play videos and music. It can also serve as one of the best free video compression software for reducing the file size of MP4, AVI, MKV, and MOV videos.

On the plus side, this full-featured tool provides you with ready-make options, like H.265+ MP3, H.264 +AAC, and you're on your own to decide the desired video codec, audio codec, frame rate, bitrate, and other properties.

However, the compressed videos sometimes have A/V out-of-sync and black screen issues. Too many important features are hidden in the menu, making it one of the most sophisticated video compressors.

Features:

  • Adjust encoding parameters to reduce video size
  • Play stream media, 4K videos, and lossless audio files
  • Rip and burn unprotected DVDs
  • Useful filters: motion blur, crop, distort, etc

Pros:

  • A wide range of input formats
  • Lower CPU usage rate when compared with most freeware

Cons:

  • Slow compression speed.
  • Difficult jargon.

Overall rating:

VLC media player's capability to compress large videos surprised me a bit. It uses 85% on average of my CPU resources to compress an H.264 video to an HEVC file.

Yes, it definitely falls behind VideoProc Converter that takes only 6% computer resources. However, it does surpass HandBrake video compressor by saving on average 5% CPU usage, in this case.

#4) HandBrake

  • Best free video compression software for cross-platform users
  • Can compress MP4, MKV, WebM, and a few more formats

HandBrake Video Compressor

If you've used HandBrake, then you've undoubtedly heard about how jampacked this cross-platform and free video compressor is.

Based on FFmpeg, this free video reducer lets you compress video files from all popular codecs including MP4, AVI, MOV, H.264, HEVC, etc. It offers you full control over video parameters, and that sounds nice.

However, beginners are always advised to stick with HandBrake preset options. Why? You'll have to climb a steep learning curve before you can apply customized settings on a video to shrink its size without A/V out-of-sync problems, missing audio, or other errors.

Features:

  • Compress more than one video file at a time
  • Rip home DVDs to digital formats
  • Downscale or upscale the video resolution
  • Ready-made setting profiles for major platforms

Pros:

  • Free and open-source
  • A plethora of tutorials are accessible
  • Excellent compression ratio

Cons:

  • Output only MKV, WebM, and MP4 files
  • Too difficult to master if you are a first time user
  • Slow compression speed and high CPU usage

Overall rating:

One of the things that I love most about this free video compression tool is it gives lots of video conversion profiles and presets, with which everyone can easily compress or convert video files for Discord Nitro, YouTube, Vimeo, and other popular platforms and devices.

#5) Shutter Encoder

  • Best free video compressor software that can color grade videos
  • Can compress popular lossy and lossless formats

50% to 90%

Shutter Encoder

Shutter Encoder is a powerful and feature-rich video converter developed by a group of passionate video editors. While there isn't a button specially designed for video compression, users can shrink MP4 to the wanted size with settings options for resolution, bitrate, file size, resolution, etc.

The range of this free video shrinker's input and output formats is very impressive, including AV1, HEVC, VP9, and GoPro CineForm. The interface might be a little bit intimidating for the first-time user, but it's well worth the time spent learning it.

Features:

  • Convert video format to HEVC/AVI to reduce the file size
  • Download video and audio files from websites
  • Rip DVDs and Blu-ray discs. Extract audio from video
  • Add fade-in effects, put subtitles/LUTs, trim video length...

Pros:

  • Support editing friendly codecs like QT Animation and GoPro CineForm
  • Free of charge. No ads or watermark

Cons:

  • Can't compress multiple videos with different output settings
  • A confusing UI that's hard to navigate
  • 99%+ high CPU usage

Overall rating:

As mentioned, Shutter Encoder is hard for beginners to get to grip with. However, if you are looking into how to make a video smaller by converting its format to AV1, then this free video compression software might be the best choice. It's one of a few video compression tools in the market that supports the input and output of AV1.

#6) FFmpeg

  • Best free video compression software for numerous advanced controls
  • Can compress MP4, MOV, MKV, and other popular formats

FFmpeg Video Compressor

FFmpeg is a piece of open-source and cross-platform audio and video processing software. It's an excellent choice for advanced users who want a powerful tool to manipulate the compression ratio, the output quality, the option of the QSV, and other settings without restrictions. Unfortunately, FFmpeg performs all tasks through the command lines.

FFmpeg is not an easy-to-approach tool. It requires you to input the correct command line to reduce the video bitrate, downscale video resolution, crop videos, mute audio, etc. The absence of the regular GUI might make once bright-eyed newbies feel hopeless.

Features:

  • Compress video to the target size or quality level
  • Support video, audio, subtitle, and picture files
  • Deshake, denoise, blur, trim, merge, rotate videos
  • Download video streaming media from links

Pros:

  • Supports a vast number of formats
  • Few restrictions on the functionality

Cons:

  • A steep learning curve
  • File compression takes a long time

Overall rating:

From compressing your video to a small size to editing the audio length, there are many uses of this convenient video compression tool. However, if you're a newcomer like me, then be ready to spend lots of time learning how to install FFmpeg on Windows/Mac/Linux and what is the right command to compress an MP4 video with FFmpeg.

#7) Any Video Converter

  • Best free video compressor software that can burn DVDs
  • Can compress 100+ video and audio formats
Supported OS Compression Ratio No Noticable Quality Loss Overall Performance

Windows, Mac

60% to 90%

Any Video Converter

Any Video Converter is a multiple-function video shrink app with a very easy-to-navigate interface and a number of presets. It's a good option for beginners who want to quickly compress or convert CDs and videos for playing or uploading on iOS, Android, Microsoft, and Sony products, etc.

Any Video Converter supports the import of 200+ video and audio formats, which is a huge number. Another big plus of this freemium MP4 compressor is it can take advantage of CUDA and NVIDIA GPU acceleration technology to compress videos. In other words, it can process your video files smoothly on a mid-range Windows or Mac.

Features:

  • Custom video aspect ratio, frame rate, and constant quality
  • Extract audio tracks from video files and DVDs
  • Record screen, burn DVDs, edit videos

Pros:

  • Support batch conversion

Cons:

  • Lack of extra features.
  • Encounter repeated failures when compressing 4K videos

Overall rating:

Any Video Converter can make use of the graphics card to compress videos, speeding up the compression process and avoiding high CPU usage. It would be my first choice if it gives up reminding me to pay the $9.99 annual subscription fee after each compression work.

#8) QuickTime Player

QuickTime Export Video

QuickTime Player isn't a typical video compressor software, but it still gets the job when you simply need to reduce the size of your video without caring so much about the picture or sound quality, this easy MP4 compressor from Apple Inc. can get the job done perfectly.

Features:

  • Play 4K HDR iPhone recording and iTunes files
  • Record screens and webcam on Mac
  • Pre-installed on Mac

Pros:

  • Easy and free to use

Cons:

  • No access to define the parameters to a specific value
  • All videos compressed by QuickTime Player will turn to MP4 format
  • High CPU usage rate and extremely slow compression process
  • Sometimes it can't read HEVC, VP9, AV1, and other videos in the advanced codec

Overall rating:

The picture quality always rolled downhill after being compressed by QuickTime Player. Even worse, this free video compressor on Mac can't read my HEVC videos.

how to compress a video with iMovie

iMovie is the go-to choice for macOS and iOS users to make simple edits. It doesn't come with the compression command, and you can't customize the video parameters.

The good thing is, though it doesn't let you dig into settings much further, iMovie allows you to assign different quality grades to your video when exporting. To put it plainly, you can throw up a video to iMovie, skip the editing steps, and pick up a relatively lower resolution, bitrate, and quality grade to get the job done. Like most other Apple software, iMovie has poor compatibility. Note: this free video compression app cannot compress MKV videos and many relatively rare video formats.

Features:

  • Allow you to trim, cut, and crop to compress video
  • Estimate the final compressed file size and length
  • Pre-installed on Mac, iPad, and iPhone

Pros:

  • 0 Learning curve

Cons:

  • Take over 90% of the CPU resource
  • A high compression ratio always brings visible quality loss
  • Can't customize the parameters for video compression

Overall rating:

iMovie is limited in comparison to most other Windows and Mac video compressors covered in this post. But for the overall performance, iMovie is stable and fast.

#10) Windows Movie Maker

  • Best free video compression software for Windows 7 with the direct options for Vimeo, YouTube, and other sites

Windows Movie Maker Video Compressor

I have to be honest here, Windows Movie Maker is known to have limited capabilities regardless you are using it as a video editing software or a video compression software. It can't compress AV1, VP8/VP9, HEVC, and many trendy video formats. Whether you feed in the MKV, AVI, MOV, or other files, you'll get H.264 MP4 or WMV files after compression.

However, I felt the need to mention it on this best video compressor list because it is pre-installed on every Windows 7 computer and used to be one of the most popular and convenient free MP4 file compressor. You'll be able to take advantage of the GPU acceleration tech to speed up the video compression process.

Features:

  • Compress videos in common formats such as MP4, AVI, and MPEG
  • Allow basic video editing
  • Instantly share your content on Gmail, YouTube, Facebook, Group, and other social media

Pros:

  • Support hardware acceleration
  • Free and easy to use

Cons:

  • Not available on Windows 8, Windows 10, and Windows 11
  • Support the output of MP4 and WMV formats only

Overall rating:

This great video compressor for PC displays the estimated video file size when you select an exported file type which is very helpful for beginners get avoid choosing the wrong file type.

Export settings in Shotcut

In the experienced hands, Shotcut can be used to make some serious video compression work. In addition to the impressive features in editing videos, it supports nearly every major video and audio codec and has a great compression ratio.

Almost everything you can do about compressing a video with a professional video compressor can get accomplished in Shotcut, though very possibly in a memory consuming and cumbersome way.

It does provide you with the Preset tab when exporting the video, however, it just lists up the supported codec, as like, HEVC main profile and H.264 baseline, with little attempt to explain the jargon. These complicated terminologies are also making the adjustments on video parameters for decreeing video file size a process of error and trial for beginners.

Features:

  • The compression ratio is on par with some professional video converters
  • Give full control over codec, bitrate, resolution, and GOP, etc.
  • As an NLE video editor, it provides a professional video editing toolset

Pros:

  • Open source and free
  • A good compression ratio

Cons:

  • Require quite a bit of education and training prior to use
  • A CPU and memory hog

Overall rating:

Just like any other NLE video editors that have timelines, you'll have to take some exploration to master all its nifty features. The first time I used Shotcut to compress a 4K 42Mbs video, the result busted up to 89Mbs. But after I realized where the error happen and corrected it, everything went flawlessly.

#12) Freeconvert

Freeconvert Video Compressor

For those of you wishing to compress videos without installing extra video compression software, Freeconvert is for you. This free online video compressor app enables you to compress MP4, AVI, MKV, or other video files from your local drive, Dropbox, Google Drive, or video URL to MP4, FLV, MKV, AVI, MOV, or 3GP file.

It lets you compress a video by adjusting the size, changing the maximum bitrate, or tuning the picture quality. For instance, if the source file is 100 MB, choose Compress video by size, and set up Reduce the file size by 50%, theoretically, you'll make it shrank to 50MB.

However, Freeconvert doesn't guarantee you a smaller result. When I added up a 26MB MP4 H.264 file to the Freeconvert video compressor, and choose to reduce the size by 1%, I finally got a 36MB compressed file which was bigger than the source. Another slightly vexing issue is the free Freeconvert video compressor doesn't allow you to compress video with a size larger than 1GB.

Features:

  • Compress video by adjusting size, bitrate, or quality
  • Compress video files up to 1 GB for free
  • Several editing options to polish your video

Pros:

  • Handle both popular and obscure video formats
  • Utterly easy to use

Cons:

  • The compression speed totally depends on your network environment
  • No for compressing large videos
  • Only support the HEVC and H.264 encoder
  • Might enlarge your source video file
  • Pop-up ads.

Overall rating:

If I have to choose one online video compressor, Freeconvert will be my option. Freeconvert video compressor is more generous than the majority of online video compression software. The largest video file you can compress with it is up to 1GB. Better yet, it's completely free.

Online Converter Video Compressor

OnlineConverter video compressor is the epitome of simplicity. Once you import a video to this free online video compressor, you can enter the desired file size, and then hit Compress. That's it. The drawback? It doesn't leave you any room to customize the basic video parameters.

The supported video size is 200MB at maximum. While the OnlineConverter video compressor allows compressing MP4, AVI, FLV, MOV, 3GP, MKV, WMV, and many other videos, it accepts the output of MP4 video only. This means everything will turn to MP4 video after compression.

Features:

  • Compress video files by setting the desired output file size
  • Compress or convert video, audio, ebook, picture, and document files
  • A few editing tools: correct color, add images/transitions/background

Pros:

  • Everything is in a few clicks
  • Compress different kinds of formats
  • Free compress video files right from the web

Cons:

  • Only enable you to compress a video by entering the desired file size
  • Bitrate, resolution, and other video parameters are neither visible nor customizable
  • Slow compression speed under a bad network connection

Overall rating:

Personally, I don't like its 80-style interface. And I don't know about you, but what's the purpose of a piece of compression software that can't compress large video at all?

MP4Compress Online Video Compressor

MP4Compress is an online MP4 compressor that attempts to help you compress MP4 files while keeping the good picture quality. Compared to all the nominated video compressors in this list, MP4Compress is perhaps the easiest option.

To use this online video compression app, all things you have to do is import a video and hit Upload Video File. As you might already expect, this MP4 compressor doesn't offer you options to select the compression ratio, bitrate, resolution, or other properties for your purpose.

However, don't worry too much. In most cases, it should satisfy your demand. I tested the compression capability of MP4Compress with some MP4 videos, and most of them were reduced to 40% ~ 75% of their original size.

Features:

  • This online MP4 compressor runs on Mac, PC, iOS, Android, Linux…
  • Compress video files up to 500MB for free
  • Extra editing tools to remove sound, remove shaky, and make grayscale videos
  • Convert MP4 video to MP3

Pros:

  • One-click to compress videos
  • Free to use without pop-up ads
  • Good compression ratio

Cons:

  • Can't set up a more optimal compression ratio or picture quality
  • As an MP4 compressor, it won't work to compress MKV, AVI, MOV…

Overall rating:

No ads, and not require registration to use. MP4compressor works like many online picture compressors, limited but efficient.

#15) 8mb.Video

8MB Video Compressor

8MB.Video is an easy-to-use and watermark-free online video compressor for Discord. It's specialized in making a video less than 8MB, 50MB, and 100MB. Thus, if you intend to compress videos under 2GBs for sending on Discord, it might be your best bet. Worry about the privacy threat issue? Then you'd be glad to see 8MB.Video's promises that all the videos you upload to its server would be deleted after 20 minutes. However, the 5-minute upload length limit makes it useless for compressing long videos, such as DVD music videos and movie recaps.

Features:

  • Compress video files up to 2GB for free
  • This online video compressor runs on Mac, PC, iOS, Android, Linux…

Pros:

  • No watermark or ads
  • 0 learning curve

Cons:

  • No custom compression options
  • 5 minutes of limit in length
  • Compress large video with terrible quality loss
  • Can't compress video to MKV, AVI, and MOV…

Overall rating:

Though the input video file size can be up to 2GB, 8MB video compressor often goes crashes when loading or compressing videos that are large in size, resolution, or frame rate.

Zamzar MP4 Compressor

Zamzar possesses the ability to compress and convert video, audio, image, document, ebook, and archive files. It has an easy-to-navigate and ads-free interface, in which a video can be added by dragging or adding a link.

Video files up to 50 MB are compressed for free, larger videos need you to purchase their paid plan. For example, you can purchase its business plan (which costs $25 per month) to increase the size limit to 2GB. Zamzar doesn't give extra options to control the compression settings. It won't display the estimated file size after compression. Thus, it's not a good option for users who want to compress video to under a specific size.

Features:

  • Compress video, audio, picture, and document files
  • This web video compressor runs on Mac, PC, iOS, Android, Linux…

Pros:

  • Ads- and watermark-free
  • Easy for beginners to use
  • This web video compressor runs on Mac, PC, iOS, Android, Linux…

Cons:

  • Only compress AVI, MOV, and MP4 files.
  • Paid to compress a video that exceeds 50MB.
  • Too limited compression features.

Overall rating:

I used several clips to test the compression ratio and overall performance of Zamzar. However, all ends up with failure. It recognized my 4K videos but always compressed them to wrong size (about 1KB). When coping with my MOV MPEG4 or MP4 H.264 video files, it returns the error message: Unfortunately, we haven't been able to compress your file to a smaller size.

What Are the Best Video Compression Software

Most desktop-based video compressors feature a variety of video formats and can custom various video properties.

The compression ratio and final picture quality depend on users' understanding of codec and compression. Thus, when choosing the best video compressor for PC or Mac, bear in mind that the rich presets and self-explained UI also matter aside from the compression rate and the processing speed.

I compare the ease of use and presets, and test their compression ratio, performance, CPU usage, and other important features with the below two video clips.

As for online video compressers, they rise in recent years in response to the need of compressing videos from the browser without installing third-party software.

However, they have a high reliance on your network environment, and the majority of them only allow you to get an output of MP4 files.

The strict limits on video size and quantities are also biggies. Thus, from my experience, they should be the last thing you want to consider.

Not put off by these limits and stick to using an online video compressor?

Well, bear in mind that the one that accepts a larger video and goes compatible with a raft of video formats is always better to go. I compare the size and format limitations of the best 5 online video compressors and test their compression ratio, performance, and other important features with the below two short video clips.

Clip 3: 32.7MB, 49 s 132 ms, 4 820 kb/s, 1980 x 720P, MPEG-4 Visual, MOV

Clip 4: 44.1MB, 34 s 480 ms, 10.7 Mb/s, 4090 x 2160P, H.264, MP4

6 Video Compression Tech that You Should Understand

1. Increase the GOP Length

What video compressor can reduce the file size by increasing GOP value: VideoProc Converter, HandBrake, ShotCut.

GOP, also known as a group of pictures, comprises one I-frame, and many P- and B-frames.

I-frame remains all data of a frame P and B frame in a GOP is predicted by I-frame. P-frame covers the differences between it and the previous I frame. B frame contains the difference between the adjacent two frames. The length of the GOP refers to the number of frames between two I-frames.

When one increases the length of GOP length, the number of I-frame decreases and the video gets to be compressed. If your video contains few motions changes, just feel no hesitate to increase its GOP length with a video compressor.

2. Convert to Another Codec with Higher Compression Efficiency

The higher the compression efficiency refers to a smaller size. H.264 is currently is the most compatible video format, and we can figure out it has a better compression ratio than MPEG4/MPEG2 and H.263.

Codec H.265/HEVC H.264/AVC MPEG4 H.263 MPEG2

Compression ratio

up to 1000:1

300~400:1

200:1

167~200:1

<200:1

Suppose you are holding an 800MB of MPEG2 video, then compressing it to an MPEG4 clip will save you 300 to 400MB of storage space. What if you want to compress an H.264 or VP8 video? Any better choice when you simply want to squeeze the size of your video without having to consider its compatibility?

Transcode your video to HEVC, VP9, or AV1. According to Netflix's test made upon 5000 12 seconds clips, VP9 and HEVC are capable of compressing the video size by 50% while still achieving the same high quality as H.264 and VP8. AV1 has a similar high compression ratio to HEVC. Suppose the source file is in H.264, a compressor that supports the HEVC codec will help you reduce the file size by half or more without sacrificing quality.

The best video compressor that lets you make the transcoding is VideoProc Converter. This fancy video compression software can compress any video to HEVC, VP9, and other advanced codecs. Meanwhile, it always keeps itself updated with the latest high entropy codec algorithm for offering you the best compression efficiency and lossless quality.

The support of re-encode is another big plus of VideoProc Converter as it lets you reduce the original file size by 80% or even more without making any adjustments on video codec or other parameters.

News: As reported by BBC, the new VVC codec could save 27% and 35% on video size more than HEVC. Thus, very possibly, VVC is the future best target format when compressing video.

3. Reduce the Frame Rate

The easiest video compressor that allows you to reduce the frame rate: Freemake, VideoProc Converter.

The high frame rate can bring you a true-to-life and smooth viewing experience when watching sports shows, video games, action movies, and other videos with fast motion content.

However, suppose your videos are about landscapes, yoga courses, photo slideshows, and other relatively static images, turning to a low frame rate is a nice idea. When the given other parameters are the same, here's the difference in file size:

Video 15FPS 24FPS 30FPS 60FPS 120FPS

1080P H.264 1hour

23.3GB

37.28GB

46.60GB

93.20GB

186.40GB

720P H.264 1hour

13.94GB

22.31GB

27.89GB

55.78GB

111.55GB

4. Lower the Bit Rate

Best examples of a video compressor that allows you to define the bitrate: VideoProc Converter, Handbrake, Shotcut.

The video bitrate in MB (Megabits) is the number of bits that are processed in a second. When other parameters of the video are the same, a higher bit rate equals a larger size and a higher quality.

For instance, an uncompressed 2minutes, 23.976fps, 1920x1080P, 35Mbps video takes storage space of 518.4MBs. The same clip of video with a bitrate of 12Mbps costs you only 172.8Mpbs of storage space.

The good part is the large consumption in space doesn't trade you with the same grade of optimization in visual experience. It's very difficult for our eyes to notice the difference between a 12Mbps and a 35Mbps HD video. Below is the recommended video bitrate for videos in different resolutions that you can take as a reference.

Resolution Bitrate of video in standard frame rate Bitrate of video in high frame rate

2160 4K video

35-45Mbps

53-68Mbps

1080P HD video

8Mbps

12Mbps

720P HD video

5Mbps

7.5Mbps

5. Downgrade the Resolutions

The best video compressor that allows you to downgrade the resolution without losing quality: VideoProc Converter.

A video with a higher resolution gets more pixels to show the details of the picture, and that is why people now like 4K UHD and 1080P videos. However, it's hard for our eyes to notice the difference when you are watching a 1080P video or 720P video on a smartphone, so is the same when watching 4K videos and 1080P videos on an HD TV or computer.

Thus you can simply downgrade the resolution from 4K to 1080P and 720P, or shrink 1080P to 720P to compress the video. From our test, VideoProc Converter is the best compassion program as it has fast response and retains over 99% of the original quality.

6. Remove the Audio Track

The fastest video compressor can shrink your video by removing the audio track in one click: VideoProc Converter.

This sounds like a weird method. But it definitely makes sense, especially when you compress a video for sharing on social media like Facebook, Linkedin, Twitter, and Instagram as 80% of people in those platforms now watch videos without sound. And you know what? 2 minutes of 32bit, 384 KHz, WAV video might come with a size larger than 350Mbs. So why not simply remove the sound from your video file.
