Convert MOV to MP4 is JavaScript that your browser has already downloaded, and it does the whole job on your own machine. On a normal site, a 5 GB video means 5 GB uploaded, a wait in somebody's queue, and 480 MB downloaded again. Here it means 0 bytes up and 0 bytes down.
- No upload
- No file size limit
- Works offline once loaded

How to use Convert MOV to MP4
- 1. Upload the MOV video and review the analysis. Drop or browse for the .mov file you want to convert. Files up to 5 GB work: the video is read in small chunks rather than loaded whole, and it never leaves your device. The tool instantly analyzes the recording and shows its duration, resolution, frame rate, codec and bitrate.
- 2. Press Convert to MP4. The tool first tries a lossless remux, which repackages the existing video and audio streams into an MP4 container without touching a single frame. That path finishes in seconds with identical quality. If the MOV uses a codec that MP4 cannot carry, the tool automatically re-encodes it to H.264 video and AAC audio instead, with a progress bar as it works.
- 3. Preview and download the MP4. Play the converted video right on the page to confirm it looks and sounds correct, check the reported input and output sizes, then download the .mp4 file. The name stays the same, only the extension changes.
When to use Convert MOV to MP4
Convert MOV to MP4 repackages QuickTime videos into the universally supported MP4 format, entirely in your browser without uploading anything to a server. Most MOV files convert losslessly in seconds, and the rest are re-encoded automatically. Use it whenever a .mov file refuses to play, upload or attach somewhere.
- Sharing iPhone videos with Windows and Android users. iPhones record .mov files that Windows Media Player and many Android apps reject; converting to MP4 makes the same footage play everywhere without any quality loss.
- Uploading footage to sites that only accept MP4. Course platforms, CMS uploaders and some social networks refuse QuickTime files outright; a quick remux to MP4 gets the identical video past the file-type check.
- Editing MOV clips in MP4-only software. Budget and web-based video editors often import MP4 but choke on MOV; converting first lets you cut and arrange the clips without hunting for codec packs.
- Converting private footage without uploading it. Online converters send your video to their servers and often cap free files at a few hundred megabytes; this tool converts multi-gigabyte recordings locally, so nothing ever leaves your machine.
