Convert MOV to MP4
Free, private MOV to MP4 conversion - processed entirely in your browser, nothing is uploaded.
iPhones and Macs record video as MOV, Apple's QuickTime container, and Windows PCs, Android phones, and many websites handle it poorly or not at all. Re-encoding to MP4 with H.264 video and AAC audio produces the single most compatible video file that exists - it plays in every browser, every phone, and every editing app. The conversion runs entirely in your browser, so the video never leaves your device.

Frequently asked questions
Does converting MOV to MP4 lose quality?
Slightly, because the video is re-encoded. This tool uses H.264 at CRF 23, a quality level where the difference is invisible for screen recordings, phone clips, and social media footage. The original file on your device is never modified.
Why won't my MOV file play on Windows?
MOV is a QuickTime container, and Windows Media Player supports only some of the codecs Apple puts inside it - newer iPhones use HEVC, which many Windows machines cannot decode without a paid extension. Converting to MP4/H.264 sidesteps the codec problem entirely.
Is there a file size limit?
The free plan handles videos up to 50MB; Pro raises that to 2GB. Because processing happens in your browser's memory, very large files also depend on your device's available RAM.
