FastAiZip - Local-first file compression for people and agents

I built FastAiZip around a simple frustration: compressing a file should not feel heavier than the file itself. Most of the time, I just wanted to make an image or GIF smaller before uploading it somewhere. But the usual flow was slow, messy, and often meant sending the file to someone else's server first. That never felt great, especially for screenshots, product assets, or anything unpublished. So FastAiZip started as a local-first way to compress files directly in the browser. Over time, the idea became bigger: not just a small image tool, but the beginning of an intelligent file compression platform. Right now FastAiZip supports JPG, PNG, WebP, and GIF. Static images and animated GIFs use separate workflows because they are different problems and should be handled that way. I also made it usable for browser agents, so local compression can be triggered from a page without building an extra upload API around it. Still early, but the direction is clear: faster compression, less friction, and more control over where your files go. If you try it, I would really love to hear what kinds of files you compress most often, and what you want FastAiZip to support next.
