How do I reduce a GIF file size?

Upload your GIF, lower the Max Colors to 64-128, optionally reduce the frame rate, and click Process. This typically reduces file size by 50-90%.

What does Max Colors do?

GIFs can use up to 256 colors per frame. Reducing this to 128 or 64 significantly shrinks file size with minimal visible quality loss. For simple graphics, even 16-32 colors can work well.

What is the Lossy Level?

It controls dithering aggressiveness. Higher values produce smaller files but introduce more visual artifacts. Start at 0 (lossless dithering) and increase only if you need maximum compression.

Will the animation still work?

Yes, the compressed GIF plays back exactly like the original — just with optimized colors and optionally fewer frames for a smaller file size.
