Optimize and download
Run the app, compare the result, and download the optimized GIF.
Common questions
Start with 128 colors. Simple graphics and icons often look the same with 32 colors or fewer. Photos and gradients need more colors to avoid visible bands.
Dithering mixes nearby colors in a small pattern to hide color bands. It makes gradients smoother, but it also makes the file larger. Choose None for the smallest file.
Some GIFs are already well optimized. Try fewer colors or no dithering. If the file is still larger, keep the original.
Platform basics
For this app, inputs and outputs are kept for up to 30 days. After that, they are deleted from our servers.
See the Privacy Policy and Terms. They explain what is stored, when it is deleted, and when third-party providers are involved.
If an app execution fails, the cost of that failed run is automatically refunded to your balance.
