Hey Product Hunt! 👋
I built PureTools because I got tired of uploading sensitive files to random websites just to compress a PDF or trim a video. Every tool I found either uploaded your files to a server, added a watermark, or required an account.
So I built 54 utilities that run entirely in your browser:
→ Video/audio via FFmpeg.wasm
→ PDFs via pdf-lib
→ Passwords via Web Crypto API
Zero server-side processing. Files never leave your tab. The service worker caches everything so it works completely offline after the first visit.
Would love your feedback — what tool is missing? 🧐
