What is WebM and why use it?

WebM is an open video format from Google designed for the web. It offers excellent compression, is royalty-free, and works natively in all modern browsers.

Can I play WebM on my phone or TV?

WebM plays natively on Android but has limited iOS/TV support. Convert WebM to MP4 for universal playback on all devices.

Should I use VP9 or AV1 codec?

VP9 has broader compatibility. AV1 offers 30% better compression but slower encoding. Use VP9 for general use, AV1 for maximum efficiency on supporting platforms.

How does WebM compare to MP4 for websites?

WebM typically produces 20-30% smaller files than H.264 MP4 at similar quality. This makes it ideal for reducing bandwidth costs and improving page load times.
