En France, la transition vers le WebM est encouragée pour les plateformes de streaming et les services publics afin d'améliorer l'accessibilité et la souveraineté numérique, évitant ainsi la dépendance à des codecs propriétaires.
About HEVC to WEBM Conversion
Short answer: yes, you can convert HEVC to WEBM online for free, and quality is well preserved with the right settings. Just upload your .hevc file to CocoConvert, pick WEBM as the output, and click Convert. The whole process takes seconds.
Now for the details. HEVC is a widely used file format. WebM is Google's open media format based on VP8/VP9/AV1 codecs, optimised for web streaming. Converting between these two formats lets you convert between formats quickly.
Your HEVC file is decoded and re-encoded as WEBM. Converting HEVC to WEBM maintains high quality with CocoConvert's optimised encoder settings.
CocoConvert runs entirely online — no software to install, no account to create. Your files are encrypted during upload (TLS), processed on isolated servers in Germany, and permanently deleted after 24 hours. It works in Chrome, Safari, Firefox, Edge, and all mobile browsers.
