Frequently asked questions
Does converting MOV to MP4 lose quality?
No. MOV and MP4 are both QuickTime/MPEG-4 containers, so this tool rewraps the exact same video and audio streams into an MP4 without re-encoding — the result is identical in quality to your source. (If a MOV uses a codec MP4 can't hold, like ProRes, it falls back to a near-lossless re-encode and tells you.)
Do my files get uploaded to a server?
No. The conversion runs entirely in your browser — your video never leaves your device and nothing is stored anywhere.
Is there a file size limit?
The remux happens on your device, so the practical limit is your machine's memory. Because it doesn't re-encode, MOV to MP4 is fast and handles large clips well.
