Why Use a GIF Compressor? (Reduce GIF File Size & Bandwidth)
An animated GIF contains a continuous sequence of image frames. This free online GIF compressor uses a specialized GIF-aware encoder to reduce animated GIF file size while keeping animations smooth and vivid. Choose compression settings based on your target file size and destination, such as Discord emojis, Slack reactions, or website banners.
How GIF Compression Works (LZW Encoding, Color Palettes & Frames)
The tool uses a local GIF encoder with lossy optimization and optional dimension scaling. GIF's LZW coding is lossless; the lossy optimization can change image detail before encoding. Compare frame detail and playback in the preview.
Compare playing previews side-by-side to inspect gradients and fast movement. Image processing occurs locally in your browser with no image uploads for compression. Download the result after checking its size and appearance.
How to Compress an Animated GIF Online in 4 Steps
- 1Choose one GIF and wait for its frame information to load.
- 2Start with Balanced, then compare the playing previews.
- 3If the result is too large, try a smaller scale or stronger level and inspect it again.
- 4Download the result only after checking its actual size and animation.
Example: reduce animation dimensions
At 50% scale, a 640 × 480 GIF becomes 320 × 240. This reduces pixels per frame from 307,200 to 76,800; it does not promise a matching 75% reduction in file bytes. Check the actual encoder result.
A GIF upload still fails
Check the current destination’s permitted format, byte limit and pixel dimensions. A file can meet one requirement and fail another. Avoid repeatedly uploading a file before inspecting those rules.
Key Benefits
- Animated output with per-file frame information
- Named compression levels and scale choices
- Playing input/output previews
- Local processing and output-size comparison
