Type a task into the search or open a drawer. Every instrument starts instantly, with no sign-up.

Text and files are processed right in your browser. Nothing is uploaded, even for large files.

Star instruments, save sets and chain text tools into flows. An account syncs them if you want.
About
Tools gathers more than 200 small instruments in one place: calculators, unit and file converters, developer utilities and text helpers. Each one opens instantly and does its work in your browser, so what you type or drop stays on your device.
Everything runs in the browser
Calculations, encodings, image compression and file conversion happen on your device. Nothing you enter is uploaded, and the tools keep working on a slow connection once the page has loaded.
No account needed
Every tool is free and works without registration. Favorites and recent tools are kept in this browser; an optional account syncs them between devices without storing the values you enter.
English, Russian and Armenian
The whole interface, every tool description and every hint is available in three languages. Switch the language at any moment and the page stays where you are.
Frequently asked questions
Are these tools free?
Yes. Every tool is free to use without limits or registration.
Is my data sent to a server?
No. Almost every tool works entirely in your browser. The only exception is the API client, which sends the request you build, and it is clearly marked.
Do I need to install anything?
No. The tools work in any modern browser on a computer or phone. You can also install the site as an app for quicker access.
