CompressGIF
Compress GIFs in your browser while keeping the animation — the official page states it's free and watermark-free — with a REST API and MCP for automation.
About CompressGIF
CompressGIF is an online GIF compression tool. The browser version runs locally in your browser, and the official page states it adds no watermark, making it suitable for shrinking GIFs to a target size for platforms like Discord. Beyond the browser tool, it also offers a REST API and an MCP interface, so compression jobs can be triggered from scripts or by AI clients. The free plan handles a small number of files at a time; Pro adds higher batch limits, a higher per-file limit, custom target sizes, and ZIP download; Developer is aimed at API usage and provides monthly credits.

Pros
- The browser version runs locally in the browser, and the official page states it adds no watermark
- Offers a REST API and MCP, so compression jobs can be scripted or initiated by AI clients
- Multiple target size presets are available on the free plan, no payment required
Cons
- The free browser tool allows at most 3 files per batch and 10 MB per file, and files can only be downloaded one at a time
- The free API provides 500 credits per month, and once the shared free compute budget is exhausted, new jobs are paused until the next month
- Unused Developer plan credits do not roll over to the next month
- The cloud API imposes additional input limits: no side longer than 4096 pixels, at most 1,000 frames, and width × height × frames not exceeding 50,000,000 — short but large animations may hit these limits first
