Free online tools
Five free online tools that run entirely in your browser. No login, no email wall, nothing uploaded — and every label, result and unit is translated into all 12 languages.
All tools
Unit & Measurement Converter
Convert length, weight, temperature, speed, area and volume between metric and imperial units — and see the same value in every other unit at the same time, so you can pick the one you actually wanted.
Text Toolkit
Count words and characters, change case, build a clean URL slug, remove duplicate lines and tidy up whitespace. Paste the text in and everything happens on your device — nothing is uploaded.
Password & Passphrase Generator
Generate a strong random password or a memorable passphrase, with an honest strength reading in bits of entropy rather than a coloured bar. Generated in your browser with cryptographic randomness.
QR Code Generator
Turn a link, a piece of text, a wifi network or a contact card into a QR code and download it as a PNG. Generated in your browser, so the address you encode never reaches our server.
Date & Age Calculator
Work out the days between two dates, your exact age in years, months and days, the number of working days in a period, or the date a given number of days from now.
These tools are for information and everyday convenience. They are not financial, legal or medical advice, and a result here should not be the only basis for a decision that matters.
