VP8 is an open and royalty-free video compression format released by On2 Technologies in 2008.

Initially released as a proprietary successor to On2's previous VP7 format, VP8 was released as an open and royalty-free format in May 2010 after Google acquired On2 Technologies. Google provided an irrevocable patent promise on its patents for implementing the VP8 format, and released a specification of the format under the Creative Commons Attribution 3.0 license.[1] That same year, Google also released libvpx, the reference implementation of VP8, under the revised BSD license.[2]

Opera, Firefox, Chrome, Pale Moon, and Chromium support playing VP8 video in HTML video tag.[3] Internet Explorer officially supports VP8 if the user has the DirectShow filter installed.[4][5] According to Google, VP8 is mainly used in connection with WebRTC and as a format for short looped animations, as a replacement for the Graphics Interchange Format (GIF).[6]

VP8 can be multiplexed into the Matroska-based container format WebM along with Vorbis and Opus audio. The image format WebP is based on VP8's intra-frame coding. VP8's direct successor, VP9, and the royalty-free AV1 codec from the Alliance for Open Media are based on VP8.[7]
