Free browser tools
Small tools that do one thing well
Every tool here runs entirely inside your browser. Nothing you open is uploaded, stored on a server, or tracked — load a page, turn off your wifi, and it still works.
Multi-PDF Viewer
Read many PDFs on one page
Open several PDFs side by side instead of hunting through a tab for each one. Arrange them one, two or three across, drag to reorder, and collapse the ones you are done with. Everything happens in your browser — nothing is uploaded.
Password Generator
Pick which symbols are allowed
Generate a password, a passphrase or something pronounceable, using your browser's own cryptographic randomness. Choose exactly which special characters may appear, so what you get is accepted by the site you are signing up to instead of rejected on submit.
Why these are free
They started as things built to solve a real problem, then cleaned up enough to share. If you want something similar built properly — for your team, your shop, or your own workflow — that is what Wuthering Studios does for a living.
