pick a tool. give it your file.
it works on your device — and stays there.

the four promises

• free. every tool is free to use. no trial, no paywall, no card.
• runs on your device. the work happens in your browser, using what your browser already has.
• nothing leaves your computer. your file is not uploaded, stored, or sent anywhere.
• no account. nothing to sign up for, nothing to log in to, nothing tracked about you.

what you actually do

• 1 · find a tool. search for what you want in plain words (“make a pdf smaller”, “read this log”) — you don't need the exact name.
• 2 · give it your file. drop the file onto the page or pick it. it opens on your device, not a server.
• 3 · get your result. the tool shows the result on the same page. download it, or keep going with another tool.

don't take our word for it

every page has a small verify link in the bottom-right. open it to watch a live log of everything the page does. if your file were ever sent somewhere, it would show up there. it doesn't — that is the whole point.

you can also open your browser's own network panel and check for yourself. nothing here asks you to trust us; it asks you to look.
