How to shrink a GIF (especially animated ones)

1. Upload the GIF

   Drop a `.gif` file into the "Image" field. Static GIFs and animated GIFs both work; for animated, the frame count, durations, and loop count are preserved.

2. Press Run

   Result returns `bytesIn`, `bytesOut`, `savedPercent`, and the optimised file. Savings come from re-quantising the palette, de-duplicating identical frames, and tighter LZW encoding — not by dropping frames or changing dimensions.

3. Realistic expectations

   Modern GIFs are usually already saved at small palettes (32-128 colours). Re-compression rarely saves more than 5–15%. For dramatic reductions, convert the GIF to MP4/WebM/WebP — those modern codecs are routinely 5–20× smaller for animation.

4. When to keep GIF

   GIF is still the safest format for autoplay in email and forum posts where MP4 wouldn't render. For a website embedding, replace with `<video>` autoplay muted loop — better quality, 10× smaller, and most browsers handle it without buttons.
