Convert MOV to MP4 Online — Free

iPhone and Mac record video as MOV (QuickTime), which most Windows players and web uploads choke on. ReFile rewraps to MP4 in seconds — usually without re-encoding, so there's no quality loss.

No signup to try
Sandboxed processing
Files deleted in 24 h

What this does

Default: stream-copy to MP4 (no quality loss, fastest)
Compress for upload — 'MP4 under 50MB' or 'for WhatsApp'
Resize — '720p MP4' or '1080p MP4 at 30fps'

How it works

1
Upload your MOV
Drop it above, or click to pick from your device. We validate the format immediately — no spinning on a file we can't process.
2
Run the conversion
The recipe runs in an isolated cloud sandbox — same as every other ReFile job. No AI guessing involved; it's a hand-written command that does one thing.
3
Download the MP4
Result lands in seconds. Files auto-delete from our servers after 24 hours; signed download URLs expire in the same window.

Frequently asked

Will the conversion lose quality?: Not if the source codecs (H.264/HEVC for video, AAC for audio) are already MP4-compatible — in that case ReFile stream-copies, which is bit-identical. If you ask for a smaller file or a different resolution, it re-encodes once.
Does it work with HEVC / H.265 MOV files from iPhone?: Yes. HEVC is a valid MP4 codec, so the rewrap is lossless. If you need broader compatibility (older devices), ask ReFile to 'transcode to H.264'.
What's the file size limit?: 100 MB on Free, 250 MB on Student, 500 MB on Pro, 2 GB on Power.
