Questions & answers
Good to know
Common questions about size, privacy, and cost.
How do I convert MOV to MP4 without losing quality?
This tool remuxes, it rewraps the existing video and audio streams into an MP4 container without re-encoding. The picture and sound are bit-for-bit identical, just in a .mp4 instead of a .mov, and it takes seconds. Everything runs in your browser.
Why can't QuickTime make an MP4?
macOS QuickTime Player only exports .mov. iPhone clips are already H.264 or HEVC video with AAC audio, exactly what an MP4 holds, so all that's needed is a container change, which is what this does.
Is anything uploaded?
No. The remux happens entirely in your browser, your video never leaves your device and nothing is sent to a server.
Which files work?
iPhone .mov and most .mov/.mkv/.m4v with H.264 or HEVC video and AAC audio. Files using unusual codecs would need a full re-encode, which this fast remux tool does not do.
Is there a size limit?
No fixed limit, but the video is processed in memory locally, so very large files can be slow or run out of memory on low-spec devices.
Does it cost anything?
No, it is completely free, no signup.
