MOV to MP4 Converter — Free, Online, No Upload
MOV files often refuse to play on Android, Windows, and old browsers. Converting to MP4 (H.264 + AAC) makes them play everywhere — and this converter does it in your browser without uploading the file.

Why use this MOV to MP4 Converter?
- iPhone MOV exports often fail to play on Windows and Android — MP4 fixes that.
- H.264 + AAC pipeline: the same combo Final Cut and Premiere export.
- Default CRF 23 is visually lossless for most footage.
- No upload — your unreleased footage never leaves your device.
How to use it
Drop your MOV into the converter
iPhone, Mac screen recordings, and DSLR exports all work. HEVC inside MOV also gets transcoded automatically.
Pick MP4 as the output format
The converter handles audio + video re-encoding to H.264 + AAC.
Download the MP4
Result plays natively in Chrome, Safari, Edge, Firefox, every Android phone, and every Smart TV.
What to watch out for
| Sometimes it is just a rewrap | A MOV that already contains H.264 can become an MP4 without re-encoding at all, which is instant and lossless. ProRes and HEVC cannot, and have to be encoded. |
|---|---|
| ProRes files grow then shrink | Converting ProRes to H.264 typically cuts the size by an order of magnitude. That is expected — ProRes is an editing format, not a delivery one. |
| Rotation is stored, not baked | iPhone MOV records orientation as a flag. If the converted file plays sideways, the flag was dropped; re-export with rotation applied. |
FAQ
Why does my MOV not play on my friend's Android?
Android lacks system-level decoders for some MOV/HEVC variants and Apple-specific atoms. Re-encoding to standard H.264 MP4 fixes that universally.
Will the conversion preserve audio?
Yes — audio is decoded from the source and re-encoded to AAC at 192 kbps by default.
Does this run in my browser?
Yes — the tool uses FFmpeg compiled to WebAssembly. Your file never uploads to a server, never leaves your device, and there is no signup or watermark.
