When to convert WebM to MP4
Recordings made in a browser, and videos saved by some apps and websites, come out as WebM. Many video editors, phones and social sites don’t accept it, while MP4 works nearly everywhere.
Good to know
- Most WebM videos need their picture converted to become an MP4, so a long recording takes a little longer than a simple file-type change. We keep the quality as close as we can.
- The result page shows the original and converted lengths so you can check nothing was cut.
- Browser recordings can be big. If the MP4 is too large to share, compress it.
Common questions
Is the quality the same after converting?
Often yes. When the video already suits the new format, the picture and sound are copied as they are and nothing is lost. When the picture has to be made again, a little quality can be lost, and the result page tells you which applied.
Is my video uploaded?
No. The conversion happens on your own device, there is no account to create, and no watermark is added to the result.
