Summary: Are you looking for free WebM editors to open WebM files, edit it, or create WebM file from other video formats? We have tested and gathered up 12 WebM editors for you.
WebM is initially designed for Web videos with its high compression ratio. The VP8 and VP9 codec makes it possible to create videos that are smaller in size and good in quality, making online video sharing easier. However, not every platform or editor add the support for this format in time.
No matter you are trying to deal with PS5 4K HDR WebM files, solve importing errors in DaVinci Resolve, look for VP9 support besides VP8, you will find the following WebM editors handy in specific scenarios.
Part 1. Best WebM Editors for Quick Editing
If you don't have any editing skill, and are terrified by those multi-track video editing software with complex UI, don't worry. The following WebM video editors support instant editing with a simple interface.
- You have a WebM video, and want to open it without error, or edit it (trim, crop, split, etc).
- You have a video of other formats, and are looking for a lightweight video editor to create WebM videos (and export quickly in a few minutes).
- You want to edit WebM video, preserve alpha channels, make GIF memes, etc.
For the above scenarios and beyond, you will find VideoProc Converter one of the best WebM editors to use on Windows and Mac. You can simply dump the video into the software, and drag the knob to cut the video, trim off unwanted sections, and merge the remaining parts together.
Without any editing skills or knowledge, you can easily crop, rotate, flip videos, change volume, add subtitles, or even edit the WebM into GIF for meme sharing. Since WebM is initially designed for Web videos with smaller size and support of transparency, VideoProc Converter will keep these merits of WebM formats.
WebM videos are usually encoded with VP8 or VP9, and VideoProc Converter supports both codecs. You can edit any WebM video in VideoProc Converter without error – or make WebM videos from MP4, MOV, MKV, M4V source files.
Editing WebM files is one tiny aspect that VideoProc Converter performs well. Check its highlighted features:

Pricing: Free for 5-minute videos (enough for short video shooters). Paid license starts at $25.95 with coupon "BLACKFRIDAY".

VLC is a media player with hidden editing functions. Following some tricks and going deep inside the menu, you can unlock VLC's ability as a WebM video editor. Though not as complete as other tools in this post, basic editing such as cropping, trimming, rotating and splicing are supported in VLC.
For detailed steps with pictures, you can follow this tutorial to edit videos in VLC. Cropping video involves multiple steps – the gist is to find the video scaling filter – you can refer to a separate guide here.
After editing WebM files, you can save them as WebM, or change them to MKV, MP4 in VLC. One thing to notice is, some filter settings will be applied next time when you are using VLC as media player. For instance, when you crop a video with VLC, the cropping frame will also take effect when you are merely playing back the video. For this concern, you need to reset the parameters back to default.
Supported OS: Windows, macOS, Linux
Pricing: Free, open-source.
Note: According to VLC Wiki, the VP8 with Vorbis is the default codecs for WebM files in VLC media player. You won't be able to edit VP9 WebM files with VLC.

This free WebM video editor is actually a video transcoder, mainly designed to convert videos. Still, it is built in with simple editing tools to crop, merge and trim videos.
The busy interface of Avidemux can be daunting with jargon. But once you get the hang of it, Avidemux can be quite handy to edit WebM, MP4, MOV and some other video formats.
Most of Avidemux's editing is done with parameter settings. Instead of use a graphic interface, users need to go deep inside settings to toggle certain features. For instance, if you want to change the brightness of WebM video, you need to navigate to Video > Filters > Video Filter manager > Colors.
Supported OS: Windows, macOS, Linux
Pricing: Free, open source.
Note: Some users from the Avidemux forum report failure of open WebM VP9/Opus file. The support for WebM encoded with VP8 works better in Avidemux.

Part 3. Best WebM Editors Online

ClipChamp is a popular online WebM editor. Microsoft acquired it on Sep. 7 2021 and also released a desktop version, making it a nice choice as Windows 11 video editor. The online editor of ClipChamp supports import WebM without any problem, and it can also keep the alpha channel of WebM. You can use WebM files as overlays, such as animated logos and motion graphics in ClipChamp.
The deal breaker is, ClipChamp only supports export to MP4, up to 1080p. There is no WebM format for the export. If you are trying to create WebM, you are out of luck with ClipChamp.
ClipChamp online editor integrates closely with social media and helps you to directly share edited videos to TikTok, YouTube, Pinterest, LinkedIn, or save to Google Drive, Dropbox, and OneDrive.

The notable missing is the 21:9 widescreen aspect ratio, if you are aiming for filmic displays. Flixier even has a recording feature to capture the screen and webcam, which is rarely seen in other online editors.
Flixier has a decent library of stock audio, overlays, transitions, shapes, and titles. The motion graphics are trendy designs, with social media Call-to-action animations. If you are a content creator, you will find them handy to ask the audience subscribe, like and share your channel.
Compared to ClipChamp, the drawback is Flixier has a limitation on render time, once you run out of the render time, you cannot create more videos until the credit refreshes in the next month. A watermark will be added at the end of the video.
As with ClipChamp, Flixier can edit WebM files, but it will export WebM into MP4. If you want to create WebM files from other formats, skip this editor.
