Optimize GIF shrinks an animated GIF's file size — entirely in your browser. Unlike most online GIF compressors, this one never uploads your file: the GIF is decoded locally, then re-encoded with two size levers you control. Reduce the colours per frame (from 256 down to as few as 8) to cut palette size, and optionally drop frames — keeping every 2nd, 3rd or 4th frame — to cut the frame count. Dropped frames' display time is folded into the frames that remain, so the GIF still runs for the same total duration, just in coarser steps. The result preview shows the new file size and the exact percentage saved. There is no watermark and no sign-up, and your GIF never leaves your device — the privacy-first alternative to ezgif and other upload-based optimizers.

Frequently Asked Questions
How do I make a GIF smaller?
Upload your GIF, lower the colours per frame (try 64 or 32), and optionally reduce the frames by keeping every 2nd or 3rd frame. Click Optimize GIF and the result panel shows the new size and the percentage saved — all computed in your browser.
What makes a GIF file smaller — colours or frames?
Both. Fewer colours per frame means a smaller palette and better compression per frame, while dropping frames removes whole frames of data. Reducing colours usually keeps motion smooth; dropping frames trades smoothness for the biggest savings. Combine them to hit your target size.
Will dropping frames make my GIF play faster?
No. When a frame is dropped, its display time is added to the frame before it, so the animation still runs for the same total duration — it simply updates less often. The playback speed stays the same, only the smoothness changes.
Is my GIF uploaded to a server?
Never. Decoding, re-quantising and re-encoding all happen locally with JavaScript in your browser. Your GIF is not uploaded, there is no sign-up, and the tool keeps working offline once the page has loaded.
