Hi Product Hunt! 👋 I built CompressFast because I was tired of uploading client design files to cloud tools just to shrink them. TinyPNG needs upload, Squoosh can't batch, everything else wants a subscription. So I made the tool I wanted: 🛡️ **100% local** — open DevTools Network panel, zero image data ever leaves your browser. Disconnect your internet, it still works. 🎯 **AVIF output** — 50% smaller than JPEG at same quality. Few online tools support AVIF encoding. 💰 **$24.99 lifetime** — not a subscription. Buy once, own it forever. ⚡ **30 images free per batch**, 500 for Pro. Drag-to-reorder, bulk ZIP download, Ctrl+V paste. Resize, rotate, strip EXIF — all in the browser. Everything runs on Canvas API + Web Workers + WASM in the browser sandbox. No servers touch your images. Would love your feedback — especially on the AVIF output quality!

Ran a batch of jpegs through it and the AVIF output was noticeably smaller without obvious quality loss. Love that it all stays in the browser, no upload waiting around.

The local-only approach with zero accounts needed is a really thoughtful call, especially for anyone dealing with sensitive images. Nice that AVIF is in the output lineup too.
