Frequently Asked Questions

How to open a WEBM file?

Chrome, Firefox, Edge, and Android open WebM natively. Safari plays WebM starting macOS 14 with AV1 hardware decoders. Older editors may require transcoding to ProRes or H.264 MP4.

What is a WEBM file?

WebM is a royalty‑free container designed by Google for the open web. It packages the Matroska profile with VP8/VP9/AV1 video and Vorbis/Opus audio, optimised for low overhead and HTML5 streaming. Announced at Google I/O 2010, WebM combined Matroska’s flexibility with On2’s newly open‑sourced VP8 codec. YouTube began offering WebM downloads the same year. Support grew as browsers added VP9 hardware decoding and will expand again with AV1.
