About the MOV to MP4 Converter

The ByteTools MOV to MP4 Converter turns Apple QuickTime MOV files into standard MP4 videos. MOV is what iPhones and Macs record by default, but it can be awkward to share on Windows, Android and many websites — converting to MP4 makes the same footage play smoothly everywhere.

It is ideal for anyone moving iPhone or camera recordings onto other devices, editors or social platforms. The video is re-encoded with H.264 and the audio with AAC, giving you a compact MP4 that keeps your original picture and sound.

All processing happens locally in your browser with a WebAssembly build of ffmpeg. Your MOV file never leaves your device — no uploads, no server and no account — so your recordings stay private and the tool works offline once it has loaded.

Frequently asked questions

How do I convert a MOV file to MP4?

Drop your MOV onto this tool and click Convert to MP4. It re-encodes the QuickTime video to H.264 and AAC audio, then lets you preview and download a universally compatible MP4 — all in your browser.

Why should I convert iPhone MOV videos to MP4?

MOV files from iPhones and Macs do not always play well on Windows, Android or older devices and some websites reject them. MP4 with H.264 is supported almost everywhere, so converting makes sharing and editing far easier.

Will converting MOV to MP4 reduce the quality?

The re-encode uses a high-quality default setting (CRF 23), so most people cannot tell the difference from the original. You get a smaller, more compatible file with visual quality very close to the source.

Is my video uploaded anywhere?

No. The conversion runs entirely on your device using WebAssembly, so your MOV file is never uploaded to a server. Private videos and personal recordings stay completely on your own computer.

Why does a long video take so long to convert?

In-browser encoding uses your own CPU instead of a remote server, so it is quick for short clips but slower for long or high-resolution videos. For large files, use a modern desktop browser and expect it to take a while.
