Compress and optimise GIF files using Gifsicle — reduce file size while keeping the animation intact, entirely in your browser using WebAssembly.
Frequently asked questions
- How much can Swirl reduce GIF file size?
- Typically 20–60% depending on the GIF content and how it was originally created. GIFs with repetitive areas compress the most.
- What method does Swirl use to optimise?
- Gifsicle, the standard open-source GIF optimiser, compiled to WebAssembly so it runs entirely in your browser.
- Will optimisation affect quality?
- At maximum compression, very subtle quality changes may be visible. The default setting balances size and quality well for most GIFs.
- Can I optimise an animated GIF without breaking the animation?
- Yes — Swirl preserves all frames and timing while removing redundant pixel data between frames.
- My GIF is already small — should I still optimise?
- If it is under 200 KB, optimising will have minimal benefit. Reducing dimensions or frame count will have more impact at that size.
