How much can GIF files be compressed?

Typically 20-60% depending on the animation complexity and color count. Simple animations with few colors see the best results.

Will the animation still work after compression?

Yes. The animation frames, timing, and loop count are all preserved. Only redundant data is removed.

Does it affect GIF quality?

GIF is limited to 256 colors regardless, so our optimizer focuses on reducing redundant frame data and improving compression without further reducing color count unless requested.

Is GIF still the best format for animations?

For web use, WebP animations and APNG are technically superior (smaller files, more colors). However GIF remains universally supported and widely used for social media.

Can I compress multiple GIFs at once?

Yes, batch processing is fully supported.

What's the best alternative to GIF?

WebP animations offer equivalent visual quality in significantly smaller files. Our GIF Maker can create WebP animations as well.

Are there file size limits?

No. Processing is local so there are no file size restrictions.
