Convert MP4 to MOV without uploading it

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

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

When the video and audio codecs inside your MP4 file are already accepted by MOV, 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.

Useful for older Final Cut or QuickTime workflows that insist on the .mov extension.

How to convert MP4 to MOV

Drop the MP4 file. It is read straight from your disk. Nothing is uploaded, so there is no waiting and no file size cap.
Keep MOV 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 MP4 to MOV lose quality?

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

How long does MP4 to MOV 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 MP4 file never leaves your device, which is also why there is no watermark, no account and no size limit.

Can I convert several MP4 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.
