You can also choose a lower resolution to compress a QuickTime video. For instance, you can save over half of the original file size by downscaling the resolution of a QuickTime video from 1920x1080P to 1280x720P.

If the original QuickTime file is lengthy, you can trim off unwanted segments to reduce the size without causing any perceivable quality loss.

Step 3. Save the Compressed QuickTime Video

Hit the RUN button and start compressing your QuickTime Video on Windows or Mac


Asides from specifying the desired size directly, you can customize the codec, bitrate, frame rate, GOP length, and more video encoding properties to make your video smaller while keeping the ideal picture quality.

How to Compress QuickTime Video Online

PS2PDF is a great piece of browser-based application that lets you compress QuickTime video online without downloading additional software to the computer or mastering any difficult terminologies.

Step 1. Open up this online QuickTime video compressor on your browser.

Step 2. Hit Add Files, and then you can choose Select From Local Disk, Select From Dropbox, or Select From Google Drive to import the QuickTime video file from your local drive, Dropbox, or Google Drive to the app. Depending on the network condition and the file size, PS2PDF might need minutes to hours to load up the file.

Step 3. Come over to the section of Output Quality and File Size. Move the slider left or right to adjust the compression ratio. In my case, I moved the slider to 50 to reduce my file (45.88MB) to half of its original size.

Step 4. Hit Compress Now to compress QuickTime video online with P2SPDF.

However, we'd steer you to VideoProc Converter AI as the online QuickTime video compressors are for the conversion of small videos only. To take PS2PDF as an example, it doesn't let you compress a QuickTime video with size exceeds 200MB. Ads on the compression page are also quite annoying.

Compress QuickTime Video Online and Mac

How to Compress QuickTime Video with QuickTime Player

QuickTime player is preinstalled on macOS computers which could be found in the Application folder. It’s not like the most other professional QuickTime video compressors in the market that enables you to fiddle with codec, bitrate, and a few more options to shrink the QuickTime video file size while retaining optimal picture quality. On QuickTime player, you can only compress the QuickTime video by exporting the original file in a lower resolution which will cause horrible quality loss unavoidably.

Step 1. Locate QuickTime player in the Application folder. Click it to open it up on your Mac machine.

Step 2. Come over to the top menu bar. Hit File to find the Import button. Click this to feed the original large QuickTime video file to QuickTime Player.

Step 3. Navigate to the menu bar and choose File again. Choose Export As from the drop-down menu of File.

Step 4. QuickTime player now offers 5 options (4K, 1080P, 720P, 480P, and audio only) for the export resolution. Select the one that is lower than the original resolution to start compressing QuickTime video for free.

Let's say my original QuickTime is in 1080P, then there I can select 720P and 480P as the export resolution.
