Compress GIF Online

Animation with large flat areas and little motion: pixels that do not change stay transparent, and similar colors extend one compression string. Photos, noise and fine dithering shrink less. Quick mode shows how small this file can get while its measured quality stays high.

With strong compression, yes, and the tool says so: the badge above the result shows the quality measured by SSIMULACRA 2 on frames at their original resolution, from no visible loss to heavy loss. Compare the original and the result with the slider before downloading.

At a very small target size, a smaller frame often looks better than a full-size frame with heavy loss. The encoder compares both by measurement and reduces the frame only when that scores higher, and the page says so next to the result. To keep the frame size no matter what, turn on “Keep frame size”.

Use Platform mode and pick Discord (20 MB, the limit without Nitro) or Discord Emoji (256 KB). The tool picks settings that fit the limit.

Yes — drop several GIF files to switch to batch mode. All files are compressed with the same settings; each result can be downloaded on its own, or all of them together as a ZIP archive.

From a few seconds to several minutes. In Target Size, Platform and Quick modes the encoder really encodes several versions of the file, so the time grows with frame size and frame count; on a phone it takes longer than on a computer.
