Convert WebM to MP4
WebM is efficient and common on the web, but plenty of phones, editors and social platforms still expect MP4. This transcodes a WebM to an H.264 MP4 with WebCodecs right in your browser, so the file is never uploaded and there is no cap on size or count.
Runs entirely in your browser — your file is never uploaded.

Frequently asked questions
Does converting change the video quality?
It re-encodes to H.264, which involves a small quality trade-off like any re-compression, but at the default settings it is visually close to the source. The upside is a file that plays everywhere MP4 is expected.
Is the video uploaded?
No. The transcode runs with WebCodecs on your own 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.
