About GifSmaller

GifSmaller makes animated GIFs small enough for the places you want to share them: Discord emoji, chat apps, social posts, docs and email.

It runs gifsicle, a widely used open-source GIF optimizer, compiled to WebAssembly. Compression happens on your own device, so your GIFs are never uploaded to a server.

How it works

When you choose a target size, GifSmaller first optimizes the GIF losslessly. If it is still too large, it searches for the gentlest lossy setting that fits, and only reduces dimensions when nothing else is enough.

Everything — previews, compression and the .zip download — is done locally in the browser tab.
