Convert WebM to MP4

Screen recordings and videos from the browser are often WebM. Many phones, messengers and video editors handle MP4 better.

How it works

  1. Open your WebM file.
  2. Keep "For all devices" selected. Use the yellow handles if you only want part of it.
  3. Click "Convert to MP4".

Questions and answers

How long does it take?

WebM usually contains VP8 or VP9 video. For "For all devices", Cutwisp re-encodes it to H.264. Depending on the length and your computer, that takes a few seconds to a few minutes.

Why is the MP4 file larger or smaller than the WebM file?

H.264 often needs a bit more space than VP9 for the same quality. Depending on the content, the file can grow or shrink.

Is my file uploaded?

No. Cutwisp processes the file inside your browser. It is never sent to a server.

Does it cost anything? Is there a watermark?

Cutwisp is free, and it doesn't add a watermark.
