What happens to your MP4

H.264/HEVC + AAC streams are copied into a QuickTime container in seconds. Choose ProRes Proxy if you need an editing-friendly intermediate (the file gets much larger).

Tip: MP4 and MOV share the same ISO base media file structure, so plain MP4 to MOV is nearly always a lossless remux.

How to convert MP4 to MOV

  1. Drop your MP4 file on the box above, or tap it to pick one. The engine (about 31 MB) loads once per visit.
  2. The converter reads the file's streams and shows which codecs are inside.
  3. Keep the defaults, or pick a quality and resolution.
  4. Press the button, wait for the progress bar, then download your MOV.

Questions

Is MOV better quality than MP4?

No. Both are containers; quality depends on the codec inside. The same H.264 stream looks identical in either.

Can I get ProRes?

Yes, ProRes 422 Proxy is available under the MOV options. Expect files several times larger than H.264.

Is my MP4 file uploaded?

No. The MP4 is read from your device by FFmpeg running as WebAssembly in the page, and the MOV is written back to your device. No server ever receives it.

Is there a size limit for MP4 to MOV?

We set none. The practical limit is browser memory: roughly 2 GB of output on a computer, and much less on phones.
