How to Compress MOV Files Online
Pick the file size and format
Choose a quality mode or target file size. Export as MP4 for general compatibility, or save the finished video as MOV.
Compress and download
Wait for the finished file-size check, then download your video.
Compress MOV Videos from iPhone and Mac
MOV files can use H.264, HEVC/H.265, or professional formats such as ProRes. H.264 is widely supported. HEVC support can vary between browsers, so the tool checks your file first and explains clearly if it cannot be processed.
Compress MOV to MP4 or Keep MOV
Choose MP4 for a widely compatible file that is easy to share. Choose MOV if you need the finished video to use the .mov file type. Both options create a new H.264 video for sharing; they do not retain HDR, transparency, or professional editing data from the original.
Reduce MOV File Size Online
Use Balanced for a general-purpose export or Smaller File for stronger compression. For sharing limits, choose Target file size. The tool checks the finished file against your chosen limit and explains what to change if it cannot meet it.
Choose the right MOV compression settings
Start with Balanced when you want a smaller file without spending time on settings. It is the sensible choice for most clips headed to cloud storage, a website, or a chat. Use Smaller File when the upload limit matters more than fine detail. If a service gives you a hard limit, enter that number in Target file size instead of guessing.
Lowering Max video height is usually the next useful lever. A 720p export is often easier to share than a full-resolution recording, especially for a short phone video. Keep audio on for a recording, tutorial, or conversation; turn it off only when the sound is not part of the clip.
A practical order to try
- 1. Balanced: a good first export when there is no fixed upload limit.
- 2. Target file size: use this for a stated size limit, then reduce the height if the target is too aggressive.
- 3. Smaller File: choose it when a share link, email attachment, or chat app still rejects the result.
iPhone MOV, HEVC, and compression problems
An iPhone MOV file may use H.264 or HEVC/H.265 video. H.264 works in most places. HEVC is more efficient, so changing it to H.264 can make a video easier to share without making it much smaller. The tool checks the file first and explains if your browser cannot process it.
ProRes, HDR color, transparency, and editing data need different handling. This compressor is for making a shareable H.264 video, not for keeping an editing master. Keep the original if you may want to edit, grade, or export the footage again.

Need a file that a service will accept?
Compression works best when the video contains only the part you need. Trim the clip before exporting to remove unused seconds. For a video where sound is not needed, remove the audio track. If the destination is Discord, use the Discord Video Compressor to work from its upload limits.

Choose a MOV file, select a quality option or target size, then compress and download it.
Can I compress MOV files from an iPhone?
Yes. iPhone MOV files may use H.264 or HEVC/H.265. The tool checks whether your browser can process the file before compression starts.
Does Keep MOV preserve HEVC or HDR?

Can I set an exact file size?
Choose Target file size. The tool aims for the size you enter and checks the finished file before it is ready to download. Very small targets may not be possible for every video.
Are my MOV videos uploaded to a server?
No. Processing happens locally in your browser, so your video is not uploaded to our servers.
