gif.js is a JavaScript GIF encoding library that runs entirely in the browser. It uses typed arrays and web workers to render GIF frames in the background for fast, non-blocking encoding.
Use cases
- create animated GIFs from canvas elements in the browser
- convert image frames to a GIF client-side without a server
- encode GIFs from video frames in a web app
- generate GIF animations with dithering and transparency
- render GIFs off the main thread using web workers
When to choose
- you need client-side GIF generation in a browser without server round-trips
- you want fast, non-blocking encoding via web workers
- you need control over frame delay, transparency, dithering, and repeat settings
When to avoid
- you need to encode GIFs in Node.js or another non-browser environment
- you need modern video formats like WebM or MP4 instead of GIF
- you need a heavily maintained library with frequent updates
