How to use Compress GIF
- Choose an animated GIF from your device.
- Choose a color limit or remove comments without changing the image data. Compare the before and after preview; download the smaller result.
- Select Apply and preview, then download the result.
Frames are processed one at a time, so long GIFs are fine. Very large frame dimensions can still exceed the local memory limit, and Reverse keeps every frame in memory at once; resize or shorten the source if needed.
Frames are re-encoded. File size may change. If a composed frame exceeds the GIF color limit, its colors are reduced; the result reports when that happens.
Frequently asked questions
- Is the compression lossless?
- It depends on the method. Remove comments only rebuilds the file without comment blocks and leaves the image data identical, so it is genuinely lossless. Reduce colors re-encodes with a smaller palette and is not lossless.
- How much smaller will my GIF get?
- There is no guaranteed reduction, and any tool promising a specific size is guessing. Already optimised GIFs may barely shrink. The result shows the original and new sizes so you can judge before downloading.
- Which color count should I choose?
- 64 is a reasonable starting point. Flat graphics and screen recordings survive aggressive reduction well; photographs and smooth gradients show banding much sooner. Compare the previews before downloading.
- Why did the tool say re-encoding did not improve the size?
- GIF already compresses its palette data, so a re-encode can come out larger than the original. When that happens the smaller original image data is kept instead, so you never end up with a bigger file.
- Is my GIF uploaded to a server?
- No. Compression runs entirely in your browser.
