Mediabunny is a pure TypeScript, zero-dependency library for reading, writing, and converting video and audio files (MP4, WebM, MP3, WAV, OGG, HLS) directly in the browser, built on the WebCodecs API. It provides lazy, frame-accurate reading, fine-grained muxing/demuxing control, and a high-level conversion API for transcoding, trimming, resizing, and more.

Use cases

• convert video files to mp4 or webm in the browser
• extract metadata like duration and resolution from a media file
• read individual video frames from an mp4 with frame-accurate timing
• trim or compress a video client-side without uploading to a server
• mux canvas recordings into a video file
• resize, crop, or rotate video in a web app
• resample or downmix audio tracks in the browser
• build a browser-based video editor

When to choose

• you need client-side media processing without a server or FFmpeg
• you want fine-grained control over muxing, demuxing, and track timing
• bundle size matters and you want tree-shakable, zero-dependency code
• you need to handle large files efficiently via lazy reading or streaming output

When to avoid

• you need server-side or native media processing outside the browser
• you require codecs or container formats not supported by WebCodecs
• you need a full-featured CLI like FFmpeg with its broad codec ecosystem
