How to convert MOV to MP4
- Choose your file. MOV, MKV, M4V, WebM or MPEG-TS.
- Leave the option unticked to copy the video with no quality loss, or tick it if a device cannot play H.265.
- Click Convert and download. The new MP4 is reopened and checked first.
When you need an MP4
- Sharing iPhone or Mac videosWindows PCs, Android phones, smart TVs and websites may handle MP4 more reliably than MOV.
- Uploading to websitesMany forms, course platforms and online shops accept only .mp4.
- Screen recordingsQuickTime on a Mac saves .mov files, which you can convert in seconds.
- MKV from OBSOBS recordings saved as MKV become an MP4 that editors can open, without a new encode.
Why this is so fast
Changing a container is like moving a letter into a different envelope. There is no need to decode and encode each frame, so even a long video is ready almost as fast as the device can read it. Sites that upload your file spend most of their time on the transfer.
Limitations
- Formats MP4 cannot carry, such as ProRes, must be re-encoded, which needs a browser that can decode them. Chrome usually cannot decode ProRes.
- AVI, WMV and FLV input is not supported yet.
- Only the main video and audio tracks are kept.
- Audio in a format MP4 cannot hold is converted to AAC.
Frequently asked questions
Is this MOV to MP4 converter really free?
Yes. It is 100% free, with no usage limits, no watermark, no account and no sign-up. There is no paid plan and no feature is locked.
Is my video uploaded?
No. Your video is opened and processed inside your browser and never leaves your device. The page only downloads its own code from this site. If you accept analytics cookies, Google Analytics receives anonymous usage data such as page views, never your video, its name or its contents.
Does converting MOV to MP4 lose quality?
Normally not. When the video inside the MOV is H.264 or H.265, it is copied into the MP4 as it is, so the picture is identical. Quality only changes if you tick “Convert to H.264”, or if the video uses a codec MP4 cannot hold, such as ProRes.
What is the difference between MOV and MP4?
Both are containers: boxes holding video and audio. MOV comes from Apple’s QuickTime and MP4 is the international standard based on it. That is why the contents can often be moved from one to the other unchanged.
My iPhone video still will not play after converting. Why?
iPhones often record in H.265 (HEVC), which some older devices and apps cannot play. Tick “Convert to H.264” for the widest compatibility. It re-encodes the video, so it takes longer.
Can it handle very large files?
Yes. Files over about 1 GB are written to your browser’s private disk storage instead of memory, if your browser supports it. In that case the MP4’s index goes at the end of the file, which is fine for playing and sharing but not ideal for web streaming.
Analytics: only if you accept cookies, the page loads Google Analytics (through Google Tag Manager) to count visits and see which tools are used. It never receives your videos, their names or their contents. You can change your choice at any time with “Cookie settings” at the bottom of the page.
