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
