About this tool
Shrinking a GIF is the most effective way to cut its file size: halving the width cuts the pixels per frame by 75%. This tool decodes every frame of the animation, scales it with a high-quality filter, and re-encodes the result with the original timing and looping intact.
Common targets: 320 px wide for chat apps and forum avatars, 480 px for social posts, 128 px or smaller for emoji-style stickers. Enlarging is possible but will look soft, since GIFs are usually low-resolution to begin with.

Questions
How much smaller will the file be?
Roughly proportional to the pixel count: resizing from 640 px to 320 px wide typically cuts the size by 70-75%.
Can I set an exact height?
Height is derived from the width to keep the proportions. Cropping to a different aspect ratio is planned.
