MOV to MP4 Converter
Convert an iPhone/QuickTime MOV video to universally-playable MP4, free and entirely in your browser. No upload, no watermark.
What is MOV?
MOV is Apple’s QuickTime container format, produced by default when you record video on an iPhone, iPad, or Mac. It typically uses H.264 or HEVC (H.265) video with AAC audio — technically similar to MP4, but wrapped differently.
Why convert MOV to MP4?
MP4 is the format every platform, device, and player supports without conversion — Windows Media Player, most Android phones, YouTube, and nearly every video editor default to it. Converting MOV to MP4 avoids the classic "this file won’t open" problem when sharing an iPhone video with a Windows or Android user.
How to convert MOV to MP4
- Drop your MOV file. Drag and drop a MOV file, or click to browse. First use loads the ffmpeg.wasm engine (~31 MB, cached in your browser after).
- Confirm output is MP4. This page pre-selects MP4 as the output format — change it in the format picker if you’d rather export something else.
- Set quality and convert. Pick a quality or bitrate preset, then click Convert. Processing runs locally on your device and typically finishes in well under a minute for short files.
- Download. Click Download to save your MP4 file. Nothing was ever uploaded to a server.
Your file never leaves your browser — conversion runs locally via ffmpeg.wasm, not on a server.
