~/edit-light-export-full

Or edit a lightweight stand-in, and swap back at the end.

Proxy editing gives you ProRes smoothness without ProRes file sizes. You cut with small, low-resolution copies; when you export, the editor quietly switches to your original full-quality footage.

~/rewrap-or-transcode

What each route does to your file.

Rewrapping moves the same video into a new box. ProRes rebuilds every frame. Here's how that plays out, point by point.

Frequently Asked Questions

Is converting MP4 to MOV free?

Yes, MP4 to MOV conversion is completely free with no signup, no watermark, and no usage limit. Convert as many files as you need.

Are my files uploaded to a server?

No. The MP4 to MOV converter runs in your browser when your file is supported there, so the file stays on your device for that workflow, reducing server exposure for that workflow. Confirm the processing mode before using sensitive content.

How long does MP4 to MOV conversion take?

Most MP4 to MOV conversions finish in under a minute. Expect a longer wait for a bigger file. It runs on your own device either way, with no account step in front of it.

Will the conversion reduce file quality?

It depends on the pair. Lossless gives you the same thing back, byte for byte. Lossy makes the file smaller and costs you something, though whether you can actually see or hear it is another question.

Does this work on mobile devices?

Yes. The MP4 to MOV converter works on phones, tablets, and desktops in any modern browser including Chrome, Safari, Firefox, and Edge.
