Simple tools that just work.
UtilTools is a growing collection of fast, free and practical online utilities for calculations, writing, conversions, data formatting, QR codes, dates, time and everyday tasks.
Built for speed
UtilTools is designed to help you get an answer quickly without digging through clutter, popups or unnecessary steps.
Useful by default
Each page is built around a real task: calculate something, convert something, count something, format something or create something.
Privacy-aware
Where possible, tools run directly in your browser so the values, text or data you enter can be processed locally on your device.
Why UtilTools exists
Many online tools are more complicated than they need to be. They can be slow, overloaded with distractions, or wrapped in unnecessary signup forms when all you wanted was a quick answer.
UtilTools was created with a simpler idea: make small, useful tools that are easy to understand, quick to use and helpful enough to bookmark.
What you can use UtilTools for
The site includes tools for percentage calculations, tips, discounts, dates, time, unit conversions, text counting, JSON formatting, Base64 encoding, URL encoding, QR code generation, password generation and more.
Some tools are built for everyday life. Others are for writing, finance, math or developer workflows. The common thread is the same: each tool should solve one clear problem without getting in your way.
Our principles
Keep tools simple
A tool should be easy to understand within seconds. The interface should explain itself.
Make pages genuinely useful
A good tool page should not only give the answer, but also explain formulas, examples and common mistakes.
Avoid unnecessary barriers
UtilTools does not require an account for ordinary tool use. The goal is fast access, not friction.
Prefer local processing
Many tools run in the browser, which keeps them fast and avoids sending input to a server when it is not needed.
What you will find here
A note on accuracy
UtilTools is designed for practical everyday use. The calculators and converters aim to be clear and useful, but results should always be checked carefully for high-stakes decisions involving legal, medical, financial or technical consequences.
When precision matters, verify the result with official sources, professional advice or the relevant standard. A handy online tool is great. A mission-critical single source of truth? Not quite. Even calculators deserve a second opinion now and then.
Guides, not just tools
Some UtilTools pages include longer guides explaining concepts such as percentages, unit conversion, tipping culture and common calculation mistakes. The goal is to make the tools useful even when you want to understand the “why” behind the result.
