Compress GIF
Smaller GIF, same loop: palette and dimension compression that keeps every frame moving — done on your device, never uploaded.

GIFs balloon for a reason: the format stores every frame with an ancient 256-color palette scheme, so a few seconds of animation can outweigh a full minute of MP4. When a GIF misses an upload limit — a Discord emote or sticker cap, a forum attachment, a README that takes forever to load — the honest levers are fewer colors and smaller dimensions. This tool pulls both, re-quantizing the palette with the same two-pass technique professionals use, and the animation comes through intact: every frame, same timing, same loop.
A truth most GIF compressors bury: if the destination accepts video, converting the GIF to MP4 or WebM shrinks it 5–10× further than any GIF-to-GIF compression ever can — modern codecs simply beat a 1989-era format. Compress here when it must stay a GIF; convert when it doesn't. Both run entirely in your browser.

Frequently asked questions
Does the animation survive compression?
Yes — that is the point of this tool. Frames, timing, and looping carry through; what changes is the color palette (re-quantized with a quality-preserving two-pass method) and, at stronger settings, the pixel dimensions.
How much smaller will my GIF get?
Typically 30–70% depending on the preset and the source. GIFs with large flat areas compress best; noisy video-derived GIFs compress least. If the result would come out larger than your original, the original is returned untouched — this tool never grows a file.
Why does the compressed GIF have slightly different colors?
GIF stores at most 256 colors per frame, and compression reduces that further, remapping each frame to an optimized shared palette with dithering. On most animations the difference is hard to spot; on photographic GIFs it shows as subtle grain.
Would converting to MP4 be smaller than compressing the GIF?
Almost always — usually 5–10× smaller at better quality, because modern video codecs are four decades ahead of GIF. If your platform accepts video files, use the GIF to MP4 converter instead; compress as GIF only when the destination truly requires the .gif format.
Is my file uploaded to a server?
No. ConvertUno runs entirely in your browser on your own device. Your file never leaves your computer or phone — there is no upload at all.
Is it really free, with no watermark?
Yes. Processing happens on your device, so serving you costs us almost nothing — no watermark, no account, no file-size limit, no daily quota.
