CompressGIF lets you shrink animated GIFs directly in your browser or through an API. The site offers a free, private compression tool that keeps the original animation intact while reducing file size. It works without adding watermarks and stores GIF files locally unless you use the cloud‑based API.

You can upload a GIF by dragging it onto the “Drop GIFs here” area, selecting a file from your device, or pasting an HTTPS image URL. After the upload, the tool shows a preview of the original and compressed animations side by side. Settings such as “Quality first,” “Size first,” and “Target size” let you choose how much compression to apply. “Quality first” keeps dimensions, frame timing, and looping unchanged, while “Size first” applies a stronger palette and lossy settings for a smaller file. “Target size” attempts to meet a specific upload limit, though it does not guarantee a fit.

If you need automated compression, the site offers a REST API and a cloud‑based MCP (machine‑learning client) service. A free API key provides 500 credits per calendar month, and the API does not require a payment card. The API and MCP run in the cloud, whereas the browser tool keeps files on your device. Examples on the site show compression from 5,938 bytes to 4,666 bytes (≈21 % saved) and from 393,536 bytes to 377,182 bytes (≈4 % saved), with settings like 256 colors and lossy level 0.

The interface provides several preset target sizes: 100 KB, 200 KB, 256 KB, 500 KB, 512 KB, 1 MB, 2 MB, 5 MB, and 10 MB. For users needing a customized limit, the Pro version allows input of any size in decimal kilobytes or megabytes. The tool also supports compressing GIFs for specific platforms such as Discord, Slack, Twitter, and Gmail, offering presets tuned to those sites' limits.
