Most "free" PDF tools upload your files to a server first. We don't. PDF Toolbox runs entirely in your browser using WebAssembly. Your contracts, resumes, and tax documents never touch a server. 20+ tools, zero signup, open the site and start using immediately. Built this because I was tired of uploading sensitive documents to random servers just to merge a few pages. Happy to answer any questions!

Hey Product Hunters! 👋

I'm sunshey, the solo builder behind sotool.

I started this because I got tired of uploading sensitive PDFs to random servers. Every time I needed to merge a contract or compress a resume, I had to trust a company I'd never heard of with my data.

So I built sotool — a PDF toolkit that runs entirely in your browser. Your files never touch a server. Everything is processed locally with JavaScript.

20+ tools, completely free, no signup.

Happy to answer any questions!
