Compress GIF images online.

Why GIF files are so large — and how to fix it.

The GIF format was created by CompuServe in 1987 — long before animated web graphics were a concern. It uses LZW compression and is limited to 256 colours per frame, which means photographic content looks grainy and banded. Worse, each frame stores the full image data, so longer animations balloon in size. A 5-second, 480p animated GIF at 15 FPS typically weighs 5-15 MB depending on colour complexity.

Our compressor gives you three strategies for GIF files. First, palette optimization — reduce the number of colours used in each frame to shrink the LZW-compressed data. Second, frame reduction — drop every other frame to halve the file size at the cost of smoothness. Third and most effective: convert the animation to WebP or AVIF, which use inter-frame compression (only storing the pixels that change between frames) and achieve 60-90% file size reduction with better colour quality.

When to keep GIF vs. convert to modern formats

Keep GIF format when compatibility is critical — some social media platforms, email clients, and legacy content management systems only support animated GIFs. Convert to WebP or AVIF when you control the delivery pipeline: modern websites, app assets, and performance-sensitive projects benefit enormously from the size reduction. WebP animation is supported by 97%+ of browsers and is the most practical replacement for animated GIFs on the web today.

For static GIFs (single-frame images that use the GIF palette), conversion to PNG or JPEG is almost always better. PNG preserves sharp edges and solid colours without the 256-colour limit. JPEG offers smaller files for GIF screenshots that contain photographic elements. Our compressor handles all of these conversions seamlessly.

Batch processing multiple GIFs

If you maintain a library of animated GIFs — for social media, email newsletters, or product demos — drop the entire folder into our batch compressor. All files process in parallel with consistent settings. The ZIP download keeps your organized folder structure intact. For individual format-specific compression, see our JPEG, PNG, WebP, and AVIF compressors.
