Use MP4 to WEBM - free
Frequently asked questions
Why convert to WEBM instead of keeping MP4?
WEBM is an open, royalty-free format built for the web and often produces smaller files than MP4 at comparable quality, which helps a website load faster.
Do all browsers support WEBM?
Yes, all modern browsers (Chrome, Firefox, Safari, Edge) support WEBM playback natively.
Does this take longer than a simple format swap?
Yes. WEBM uses different codecs than MP4, so this is a full re-encode rather than a fast container remux.
