Shortcuts
Why convert MOV to MP4?
MOV is Apple’s QuickTime container. Many iPhone videos also use HEVC (H.265), which some Windows PCs, older TVs and websites can’t play. Converting to MP4 with H.264 video and AAC audio makes the file play almost everywhere.
Frequently asked questions
Is my video uploaded?
No. ffmpeg runs in your browser tab and reads the file from your device. The page’s security policy doesn’t allow it to send data anywhere; the Privacy check lists every request.
Why is the first conversion slow to start?
The converter engine (32 MB) downloads once from this site. After that it’s cached by your browser.
Which formats can it read?
Almost anything FFmpeg supports: MP4, MOV, WebM, MKV, AVI, FLV, 3GP and more, including HEVC iPhone videos.
