Frequently Asked Questions

The optimizer re-encodes your GIF with fewer colors and optimized encoding. Reducing the color palette from 256 to 64 or 32 colors can dramatically reduce file size while maintaining visual quality.

The animation timing and frames are preserved. Only the color palette and encoding are changed. Your GIF will play exactly as before, just with a smaller file size.

64 colors offers a good balance. 32 colors gives smaller files but may show banding in gradients. 128 colors is nearly indistinguishable from the original for most GIFs.

No. All optimization happens locally in your browser using JavaScript. Your files never leave your device, ensuring complete privacy.

GIF is inherently inefficient for photographic content. For photos or complex images, consider converting to WebP or reducing dimensions. GIF works best for simple graphics and animations.

Yes. Both original and optimized GIFs are shown side-by-side so you can compare quality before downloading the optimized version.

Transparency is preserved during optimization. If your GIF has transparent areas, they will remain transparent in the optimized output.

Typically 30-70% reduction depending on the original GIF and settings. Simple graphics see larger reductions; complex animations see smaller gains.

Yes. Reducing dimensions is the most effective way to reduce file size. A 50% size reduction can result in 75% smaller file size.

Yes, but large GIFs may be slow to process on mobile. For best performance, use a desktop browser with adequate memory.
