MOV is Apple's container. Many MOV files already hold H.264 video and AAC audio, so they can be moved into an MP4 container in seconds without touching the picture.
This tool checks for that first. If the contents are not compatible, for example HEVC video from a newer iPhone, it re-encodes to H.264.
MOV to MP4: what to know
iPhone HEVC
Newer iPhones can record HEVC. YouTube accepts it, but some editors and older devices do not, so converting to H.264 is the compatible choice.
Colour and HDR
HDR footage may look flatter when converted to a standard MP4. If colour matters, upload the original to YouTube instead.
How to use
- Add your video. Drop a MOV, WebM, AVI, MKV, FLV or other video file into the tool.
- Choose a mode. Automatic tries a fast copy first. Choose always re-encode if you need the most compatible result.
- Convert. Press the button. A copy finishes in seconds, a re-encode takes about as long as a quarter to a full playing time depending on your device.
- Download the MP4. Preview it, then download. The original file is not changed.
Limits and good to know
- Files over about 500 MB can run out of browser memory on some devices.
- Re-encoding is slower than copying and uses more battery on a phone.
- A few rare codecs cannot be decoded in the browser. If a file fails, try another source file.
FAQ
Is copy mode really lossless?
Yes. The video and audio streams are copied into the new container as they are.
Why is the MP4 a different size?
A re-encode changes the size. A copy stays nearly the same.
Is this converter free?
Yes. There is no limit, no account and no watermark.
Is my video uploaded?
No. It is converted in your browser.
Will it reduce quality?
Copy mode does not. Re-encoding at the high setting is very close to the original.
