About SlimGIF

SlimGIF is an independent GIF compression website made and maintained by the SlimGIF site operator. It helps you reduce GIF size, compare the original and result, and download a GIF processed in your own browser.

What this site does

The tool uses Gifsicle 1.92 as WebAssembly in a browser worker, with the gifsicle-wasm-browser wrapper. It can optimize GIF frames, reduce colors, apply optional lossy compression, and resize dimensions. Smaller output is not guaranteed. It processes one GIF at a time.

Open-source components

The engine and wrapper have separate licenses. Their license texts and source archives are available through the links below.
