Free tools
Small tools that do one thing well
Things built to solve a real problem, then cleaned up enough to share. They are free, they need no account, and they run entirely inside your browser.
Multi-PDF Viewer
Read many PDFs on one page
Open several PDFs side by side instead of hunting through a tab for each one. Lay them out one, two or three across, drag to reorder, and collapse the ones you're done with — useful for comparing quotes, invoices, or drafts.
Open the tool ↗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.
Open the tool ↗Your files never leave your device
These tools have no server to upload anything to. Your file is opened by your own browser, and the page holds no cookies and runs no analytics. If you want to check rather than take our word for it: load a tool, turn off your wifi, and it still works.
