This is an improvement over the existing WebGL interfaces, which were designed for drawing images but could only be repurposed for other kinds of computations with great effort. It provides modern features such as 'GPU compute' as well as lower overhead access to GPU hardware and better, more predictable performance. The WebGPU API is the successor to the WebGL and WebGL2 graphics APIs for the Web. For more information, see Video processing with WebCodecs. This feature has also completed its origin trial in Chrome 93 and is now available by default. The WebCodecs API eliminates these deficiencies by giving programmers a way to use media components that are already present in the browser. A low-level codec API would better support emerging applications, such as latency-sensitive game streaming, client-side effects or transcoding, and polyfillable media container support, without the increased network and CPU cost of JavaScript or WebAssembly codec implementations.

WebCodecsĮxisting media APIs ( HTMLMediaElement, Media Source Extensions, WebAudio, MediaRecorder, and WebRTC) are high-level and narrowly-focused.

Unless otherwise noted, changes described below apply to the newest Chrome beta channel release for Android, Chrome OS, Linux, macOS, and Windows.
