About Tools
Small instruments, built with care
Tools is a bench of more than 200 everyday utilities for numbers, files, code and text. Each one opens in a second, does one job well and keeps your data on your own device.
01Why we built it
Most online utilities ask you to upload a file, wait for a server and scroll past ads to get a simple answer. We wanted a bench where the instrument is ready the moment you open it and nothing leaves your computer. Tools is made by bob.am in Armenia. The interface is written in English, Russian and Armenian from the start, so every instrument, hint and error speaks your language.

03What we care about
Your data stays with you
Calculations, conversions and file processing run in your browser. We never see the text you paste or the files you drop. The only exception, the API client, is clearly marked.
No sign-up wall
Every instrument works without an account. An optional account only syncs favorites, sets and flows between devices, never the values you enter.
Honest tools
Errors are shown instead of guessed, progress bars follow real work, and each tool says plainly what it does and what it does not do.
