MP4 to MOV Converter

Repackage an MP4 into a QuickTime .mov for Apple apps — fast and lossless. Runs on your device; nothing is uploaded.

Drop your file here, or click to choose Processed privately in your browser — nothing is uploaded

100% private. Your file is processed in your browser with ffmpeg (WebAssembly) and is never uploaded. Big or long files take longer and use more memory — for those, trim first.

How to Use the MP4 to MOV Converter

Three steps, all in your browser.

1

Load your MP4

Drag an .mp4 onto the box or click to choose one.

2

Convert to MOV

Click Convert. Because MP4 and MOV share the same H.264/AAC streams, the tool copies them straight across — fast and with no quality loss.

3

Download the MOV

Preview and download the .mov, ready for QuickTime, Final Cut, iMovie and Keynote.

Frequently Asked Questions

How do I convert MP4 to MOV?
Load your .mp4 file and click Convert. Because an MP4 usually already contains H.264 video and AAC audio — the same streams a MOV uses — the tool remuxes them into a QuickTime container without re-encoding, so it’s fast and lossless. Then preview and download the .mov.
Why convert MP4 to MOV?
Some Apple applications — QuickTime Player, Final Cut Pro, iMovie and Keynote — prefer or expect the .mov container. Converting lets an MP4 drop into those apps cleanly while keeping the exact same video and audio quality.
Does converting reduce quality?
No. This conversion is a remux: the video and audio are copied from the MP4 into the MOV container untouched, so there is no re-encoding and no generation loss. The picture and sound are identical to the source.
Is my file uploaded to a server?
No. The remux runs entirely in your browser with ffmpeg compiled to WebAssembly, so your video is never uploaded, stored or logged, and it works offline once the page has loaded.
What if my MP4 uses an unusual codec?
The fast copy works when the MP4 holds standard H.264/AAC, which is by far the most common case. If you have an unusual codec that a MOV can’t hold, convert it to a standard MP4 first, then to MOV.
