What is JustUse.me?
JustUse.me is a free, privacy-first online toolbox with 122 browser-based tools for everyday file tasks. Every tool runs entirely in your browser using WebAssembly and Canvas APIs — your files are never uploaded to any server. No account required, no watermarks, no hidden fees.
Why choose JustUse.me over other online tools?
Most online file tools like Smallpdf, iLovePDF, and TinyPNG upload your files to their servers for processing. JustUse.me is different: all processing happens client-side in your browser. This means faster results (no upload/download wait), true privacy (files never leave your device), and zero risk of data leaks.
