About this tool

Screen recordings and WebM downloads open here. WebM is a video container, not WebP.

Questions

What can I open in WebM Editor?
WebM Editor accepts WEBM. Older video containers such as AVI, WMV, FLV, MPEG and 3GP are decoded by the server encoder.
Does WebM Editor upload my file?
Browser-native formats stay in this tab. Formats the browser cannot write (AVI, WMV, HEVC, AMR and similar) go to our encoder and are deleted after the download.
How large can the file be?
Free: 500 MB and 8 exports a day. Plus (waitlist) raises the daily cap. A pasted public file URL is also accepted.
