Convert M4V to MP4
M4V is Apple’s MP4 variant, and while the two are nearly identical, some players and editors balk at the .m4v extension or its packaging. This transcodes an M4V to a standard H.264 MP4 with WebCodecs in your browser, so it plays everywhere MP4 is expected — and the file is never uploaded.

常見問題
Isn’t M4V basically MP4 already?
Almost — they share the same container, but M4V can carry Apple-specific packaging that trips up some players and editors, and converting to a plain MP4 removes that friction. One limit: M4V files with FairPlay DRM (older iTunes purchases) can’t be converted, because the media is encrypted.
Is the video uploaded?
No. The transcode runs with WebCodecs on your device, so the video never leaves the browser — no account, no quota, no size limit. Chrome, Edge and Firefox work best; Safari’s video encoding is more limited.
