Compress GIF Under a Target Size Online

Quick Answers
- The engine is a WASM build of gifsicle — the same engine desktop GIF tools have relied on for years, with three levers: lossless optimization (-O3), palette reduction (128/64 colors is usually invisible), and frame-rate reduction.
- GIF uses 256-color indexed color plus LZW, and routinely runs an order of magnitude larger than MP4 for the same content: an already-optimized GIF has almost no headroom at its original size — resize, cut colors, or drop frames to actually shrink it.
- Output is never larger than the original (an original-file guard returns your file unchanged when it can't be compressed); results stay GIF, which is typically larger than WebP/MP4 at the same dimensions.
- Everything runs in your browser — free, no watermark, no sign-up, nothing uploaded.
How to Reduce GIF File Size
- 1
Upload your GIF file
- 2
Choose the frame rate, output width, and color count
- 3
Click Compress, then download the smaller GIF
Common Uses
- Get GIFs under a platform's size limit
- Shrink GIFs so they send easily over chat apps
- Produce smaller placeholder or thumbnail animations for the web
Things to Keep in Mind
- Compression is lossy — cutting colors or frame rate too far visibly degrades the image
- GIFs with very few frames gain little from frame-rate reduction
- Output stays GIF, which is typically larger than equivalent WebP/MP4
How to Choose a GIF Compressor
- vs. ezgif and other online tools: nothing is uploaded — private and secure
- vs. the Image Compressor: this page is purpose-built for GIFs, with frame-rate and palette controls
- The animation is preserved — your GIF won't collapse into a still image
Why GIFs Don't Compress Much
- GIF file size comes from three 1980s constraints: every frame is stored in full (no modern inter-frame prediction), a 256-color ceiling, and LZW compression. A GIF that's already well optimized has very little left to squeeze.
- The effective levers are all subtraction: drop the frame rate (half the frames, roughly half the size), shrink the dimensions (pixels fall off quadratically), reduce the color count (smaller palette, cheaper indexes).
- For the same content, WebP or MP4 typically runs 1/5 to 1/10 the size of GIF. GIF's one irreplaceable advantage is that it displays everywhere, with no player required.
GIF Compression FAQ
Will compression remove the animation?
No. Frame rate and color count go down, but the animation keeps playing continuously.
How do I make a GIF under 2MB or another target size?
Enter a target size in KB, then adjust the output width or frame-dropping ratio if the first pass still misses the goal. Lowering both dimensions and frame rate is the most reliable way to get a large GIF under a fixed limit.
Why is my GIF still big after compressing?
GIF is a 256-color format with limited headroom. If you need it much smaller, convert to WebP or MP4 instead.
How low should I set the color count?
128 colors is visually safe for most GIFs; 64 works when you need aggressive shrinkage, but gradients may shift in color.
Is my GIF uploaded anywhere?
No. Compression runs locally in your browser via FFmpeg WASM — your file never leaves your device.
Can I hit a specific file size?
Lower the frame rate, dimensions, and color count step by step to shrink significantly — try a few combinations and compare.
