Summary: If you need to convert WebM to AVI free or online, look no further! In this post, we list 4 of the best ways to convert WebM to AVI effortlessly.
WebM is an open-source container format developed by Google. Video streams in WebM files are typically encoded using VP8, VP9, and AVI codecs. These codecs feature a high compression ratio and great quality, making WebM one of the best formats for video streaming. However, sadly, not all media players and platforms can read and handle WebM files.
- Safari on macOS Catalina (or earlier systems) does not support WebM files.
- Recent macOS systems support only WebM files that store VP8/VP9 video streams and Vorbis audio streams.
- Twitch, Utreon, Flicker, Veoh, and many social media & video platforms do not accept WebM files.
To make your WebM video playable or sharable on major platforms or devices, it's better to convert its format from WebM to AVI, the latter supports more video & audio codecs and is supported by most media players and social media platforms.
