Why WEBM?
WEBM is an open, royalty-free video format designed for the web. Using VP9 video and Opus audio, it often gives good quality at modest file sizes, which helps pages load faster and is supported by all modern browsers.
To keep conversions quick, output is limited to 720p: larger videos are scaled down and we tell you when that happens. VP9 encoding takes longer than MP4, so you'll see a real progress bar while it works.
