Convert your MP4 videos to WebM format using our free online tool. WebM is an open-source video format optimized for the web that provides excellent compression and broad browser compatibility. No Signup Required.
The MP4 format was standardized in 2001 as part of the MPEG-4 standard, while WebM was introduced by Google in 2010 as an open-source, royalty-free alternative.
WebM uses VP8/VP9 video codecs and Vorbis/Opus audio codecs, providing excellent compression for web delivery.
While MP4 is widely compatible across devices, WebM offers better compression efficiency and is natively supported by most modern web browsers.
This makes WebM ideal for HTML5 video embedding and streaming applications where bandwidth efficiency matters.
Converting MP4 to WebM involves transcoding video and audio streams from MP4's H.264/AAC combination to WebM's VP8/VP9 and Vorbis/Opus codecs.
This process optimizes videos for web delivery by providing better compression at the expense of some quality and processing time.
WebM was specifically designed for web use, with a focus on balancing quality and file size, making it advantageous for streaming platforms.
All major browsers including Chrome, Firefox, Edge, and Opera support WebM natively, though Safari support is limited.
For web developers, WebM offers a free, open standard that reduces bandwidth costs while maintaining acceptable visual quality.
Pro Tip: Converting from MP4 to WebM is ideal when you need to optimize videos for web delivery, reduce bandwidth usage, or ensure compatibility with HTML5 video players.
