A pure JavaScript library that encodes HTML5 canvas content (single frames or animations) into GIF images, ported from the ActionScript as3gif GIFEncoder. It runs entirely client-side using LZW encoding and NeuQuant color quantization.
Use cases
- export html5 canvas animation as gif
- create animated gif in browser from canvas frames
- save canvas drawing as gif image
- record canvas animation client-side without server
- convert canvas image data to gif in javascript
When to choose
- you need client-side GIF generation from canvas with no server dependency
- you want a small dependency-free JavaScript GIF encoder
- you're capturing canvas animations frame by frame in the browser
When to avoid
- you need modern maintained tooling or active support
- you need GIF decoding rather than encoding
- you need high-performance or WebP/video output formats
