Convert MOV to MP4 without uploading it

MOV is Apple’s QuickTime container, the default for iPhone recordings and Mac apps. MP4 is the most widely supported video container in the world, playable on every phone, browser, TV and editing app. Switch from one to the other on your own device: drop the file, click convert, download.

Why convert MOV to MP4? Because many Windows programs, Android phones and web players refuse it or need extra codecs, while it plays everywhere without extra software. MOV files usually contain H.264, HEVC or ProRes video with AAC or PCM audio; MP4 expects H.264 or HEVC video with AAC audio.

When the video and audio codecs inside your MOV file are already accepted by MP4, the conversion only rewrites the container. That is a remux: no quality is lost and even a multi-gigabyte file finishes in seconds. If a codec is not accepted, that stream is re-encoded on your device at a bitrate matched to the original.

iPhone videos are usually H.264 or HEVC inside a MOV, so this conversion is nearly always an instant remux.

How to convert MOV to MP4

Drop the MOV file. It is read straight from your disk. Nothing is uploaded, so there is no waiting and no file size cap.
Keep MP4 selected. Leave “maximum compatibility” on so the result plays everywhere, or turn it off to always copy the streams unchanged.
Convert and download. Preview the result and save it. The original file is untouched.

Questions people ask

Does converting MOV to MP4 lose quality?

Not when the codecs already fit: the video and audio data is copied byte for byte. Only streams that MP4 cannot hold are re-encoded, and then at a bitrate matched to the original.

How long does MOV to MP4 take?

A remux of a one-gigabyte file takes a few seconds on any recent laptop. Re-encoding runs at several times real-time speed on hardware encoders.

Is it really free with no upload?

Yes. The page is a static website and the conversion runs inside your browser using its built-in video engine. Your MOV file never leaves your device, which is also why there is no watermark, no account and no size limit.

Can I convert several MOV files?

One file at a time for now. After downloading, click “Start over with another file” and drop the next one. Batch conversion is on the roadmap.
