How to: Compress GIF
- Upload one or more animated GIFs.
- Choose colours, size, frame dropping and lossy compression.
- Download the smaller GIF.
GIFs are the universal animation format, but they get large quickly, and chat apps, forums, email and documentation sites often reject big files. This compressor rebuilds your GIF with fewer colours, smaller dimensions, fewer frames or a lossy pass that reuses pixels between frames – four simple levers to make it fit.
Common uses
- Get GIFs under upload limits on Discord, Slack, forums and email.
- Speed up pages and README files that contain animations.
- Shrink screen-recording GIFs for bug reports and tutorials.
- Reduce reaction GIFs and stickers for messaging apps.
Tips for best results
- Start with 128 colours and the lossy option – most GIFs look the same.
- Reduce size to 75% for screen recordings with large empty areas.
- Drop frames only for long or high-frame-rate GIFs.
- For very long clips, convert to MP4 instead with GIF to MP4.
Why GIFs are so big
GIF stores each frame using up to 256 colours and compresses only by repeating patterns, with no motion prediction like modern video codecs. Noisy pixels or dithering that change from frame to frame break those patterns. The lossy option replaces pixels that barely changed with the previous frame's colour, creating long identical runs that compress well.
Private and offline
Decoding and encoding happen in your browser, so even GIFs of private screens are never uploaded.

Frequently asked questions
How much smaller will my GIF be
Results vary. Reducing to 64 colours and 75% size often halves the file; dropping every second frame can halve it again. The result panel shows the size before and after so you can try other settings.
Will the animation speed change if I drop frames
No. When frames are dropped, the delays of the removed frames are added to the remaining ones, so the animation keeps its original timing – it just looks a little less smooth.
