how to convert mov to mp4
Drop your MOV file
Drag your MOV file into the drop zone above, or click the box to pick a file from your computer or phone. The browser reads the file directly — nothing uploads.
Click Convert
The page runs ffmpeg.wasm on your device to decode the QuickTime Movie and encode it as MPEG-4 Part 14. Most conversions finish in a few seconds; large or codec-heavy files (RAW, video) can take longer.
Download the MP4 file
When the conversion finishes, the MP4 file is ready to download. Save it anywhere on your device.
FAQ
common questions
Why convert MOV to MP4?
MOV is Apple's QuickTime container; MP4 is the universal video format. iPhones, iPads, and Mac cameras produce MOV by default, but many non-Apple platforms — older Windows tools, Android-only apps, some upload portals, smart TVs — don't play MOV natively. MP4 plays on essentially every device and platform without complaint.
Will the video quality stay the same?
Very close. MOV and MP4 are similar containers (both descend from the QuickTime spec), often holding the same H.264 video codec. The converter re-wraps the codec stream into MP4's container without re-encoding when codecs are compatible — that's lossless. When codecs differ (e.g. MOV with ProRes), the converter re-encodes to H.264 for MP4 compatibility, which adds a small generational loss but stays visually faithful.
Will the file size change?
Slightly. MOV and MP4 use similar container overhead, so the size is nearly identical when re-muxing. Re-encoding from ProRes (a high-bitrate Apple codec) to H.264 typically produces much smaller files — ProRes is uncompressed-style and yields huge files; H.264 in MP4 compresses heavily. Casual MOV from iPhone (already H.264) stays similar size.
Will audio survive correctly?
Yes. iPhone MOV files typically use AAC audio, which transfers directly to MP4 without re-encoding (lossless re-mux). MOVs from professional editing tools may use Linear PCM or other codecs that get re-encoded to AAC for MP4 compatibility.
What about HDR, Dolby Vision, ProRes Log footage?
Advanced metadata (HDR colour tags, Dolby Vision, Apple Log curves) may not round-trip cleanly when re-encoding. Re-muxing without re-encoding preserves these; transcoding to a different codec usually flattens them. For professional video workflows, keep the original MOV — converting to MP4 is best for sharing the visible result, not for archival or further colour grading.
