How to Compress GIF File Size
Vizua is a free online GIF compressor that runs entirely in your browser. Unlike cloud-based services, your files are never uploaded to any server — everything is processed locally using advanced compression algorithms.
To compress a GIF, drop your file into the area above and adjust the color palette size. Our engine re-encodes the GIF with an optimized color table, achieving 20-60% smaller file sizes while preserving visual quality.
Why Compress GIF Files?
- Faster page loads — compressed GIFs load faster on websites and improve Core Web Vitals scores
- Share anywhere — messaging apps, forums, and social platforms often have file size limits for GIFs
- Save storage — reduce the size of your GIF collection without deleting files
- Lower bandwidth — smaller GIFs mean less data transfer for mobile users and your hosting bill
How GIF Compression Works
GIF files use a 256-color palette per frame. Our compressor analyzes each frame and builds an optimized palette with fewer colors, then re-encodes using LZW compression. Reducing from 256 to 128 colors typically saves 30-40% with almost no visible difference on most animations.
Browser processing
Every GIF you compress stays on your device. The selected file or entered content is processed in the browser and is not sent to our image-processing server. Vizua may still make network requests for site features and required assets.
