# JustUse.me

> Free browser-based file tools. No uploads, no sign-up, no watermarks. Every tool runs in your browser — your files never touch a server.

JustUse.me is a privacy-first alternative to Smallpdf, iLovePDF, and TinyPNG. Unlike those services, files are processed entirely client-side using WebAssembly and Canvas APIs. Nothing is uploaded. There are 30 tools across PDF, image, text, and code categories. Free to use (3 times/day per tool), no account required.
