Why Convert MP4 to WebM?
WebM is an open, royalty-free format developed by Google specifically for web video delivery. Unlike MP4 which uses patented H.264/H.265 codecs that require licensing fees, WebM uses the free VP9 or AV1 codecs, making it the ideal choice for commercial websites and web apps.
VP9 and AV1 codecs inside WebM deliver comparable or better visual quality than MP4 at significantly smaller file sizes. This reduces your hosting bandwidth costs, improves page load times, and provides a smoother streaming experience for your website visitors.
