Why convert WebM to AVI?
Both WebM and AVI use lossy compression, so the conversion mainly changes compatibility, not quality. The main reason to convert WebM to AVI is compatibility: AVI plays back smoothly in browsers and on mobile without a codec pack, while WebM doesn't always. If you're sharing a file with someone else, sending it to a tool that expects a specific format, or archiving it for the long term, AVI is usually the safer target.
