How to use it

  1. 1Drop a MOV, WEBM, AVI or other video onto the box, or click to choose a file.
  2. 2Click Convert to MP4 — the in-browser engine re-encodes it to a standard H.264 MP4.
  3. 3Play back the result and download your MP4.

MP4 is the format that just works. Whether you are dropping a clip into a video editor, posting to a social feed, embedding it in a slide deck, or sending it to a teammate, MP4 with H.264 video is the safest bet for compatibility. A file that came off your phone as a MOV, out of a screen recorder as a WEBM, or out of an old camera as an AVI can choke on the very player or platform you need it for — and converting to MP4 fixes that.

This tool does exactly that. Your video is processed entirely inside your browser using an in-browser video engine — there is no upload, no server, no watermark, and no account. The file you drop in stays on your machine the whole time, which makes it safe for confidential demos, client work, and anything you would rather not hand to a random website.

It accepts MOV, WEBM, AVI, MKV, MP4 and most other common video formats, and outputs a standard MP4 encoded with H.264 video and AAC audio — the combination that plays on virtually every device, browser, editor, and platform. The conversion re-encodes the file with sensible quality settings so the result stays sharp without ballooning in size.

Because everything runs locally, there are no upload waits and no file-size limits beyond what your own machine can handle. Drop in a clip, click convert, and download an MP4 that goes wherever you need it.

FAQ

Is this tool free?
Yes — completely free, with no sign-up, no watermark, and no limits. It runs entirely in your browser.
Is my video uploaded anywhere?
No. Everything happens locally in your browser. The video is never sent to a server — it stays on your device the entire time.
Which formats can I convert from?
It accepts MOV, WEBM, AVI, MKV, MP4 and most other common video formats. Just drop the file in and convert.
What does the output file look like?
You get a standard MP4 with H.264 video and AAC audio — the format that plays everywhere and imports cleanly into editors and social platforms.
Why does the first run take a moment?
The first time you use it, your browser downloads the in-browser video engine (about 30 MB) once. After that it is cached, so later conversions start instantly.
