About WebM
WebM is an open, royalty-free video format developed by Google and based on the Matroska container. It holds VP8, VP9 or AV1 video with Vorbis or Opus audio.
It is made for the web: all major browsers play it in the HTML video element, and it is common for screen recordings and short clips.
WebM allows only its own small set of codecs, so H.264 video or AAC audio has to be re-encoded to fit.
Convert WebM to AVI online free, no account required — AVI is Microsoft's older Windows video container.
Change WebM to AVI without losing quality — convert WebM to AVI free in your browser.
Why can't I upload my WebM video to Instagram or TikTok? Social apps almost always demand MP4, so a WebM made for the web needs converting before it will upload.
About AVI
AVI (Audio Video Interleave) is a container format Microsoft introduced in 1992 for video on Windows.
Older cameras, Windows software and video collections from the 1990s and 2000s.
AVI predates modern codecs and has no native support for features such as variable frame rate, so it is rarely used for new video.
Why convert video to AVI today? Mainly for older Windows software and DVD-era players that accept nothing else.
