About uTooler
uTooler is a collection of free, fast online tools and browser games. No sign-up, and your data is not sent to our server.
What we do
We want the small everyday tasks to take seconds, without sign-up forms or clutter: working out a percentage, adding VAT, merging PDF files, compressing a photo, or taking a break with a game of solitaire.
How it works
Almost every tool on uTooler runs entirely in your browser. The numbers, text, images and PDF files you use never leave your device; the work happens on your own computer or phone. That keeps the tools fast, even on a slow connection. Exceptions are stated on the page itself (for example What Is My IP asks outside services to look up your address). See the privacy policy for details.
Our principles
- Free, no account: no tool asks you to sign up.
- Privacy: no cookies and no tracking scripts; your settings stay in your own browser.
- Accuracy: calculations use widely accepted formulas and sources (for example WHO categories for BMI and CDC percentiles for children). Each tool page explains how the result is worked out.
- Speed and accessibility: light pages, comfortable on phones, keyboard and screen reader friendly, with light and dark themes.
- Two languages: every tool is available in English and Turkish; use the language link at the top of the page to switch.
What you will find
Tools are grouped into six categories: Calculators (calculator, percentage, VAT, compound interest, age, BMI, calories and more), Converters (merge PDF, image compressor and converter, unit and time zone converter), Text (word counter, password and QR code generator), Device tests (webcam, mic and screen test, what is my IP), Random (decision wheel, random numbers, dice) and Games (solitaire, sudoku, minesweeper, chess, checkers, mahjong and more). New tools are added regularly.
