Util Tools is a growing library of fast, free, browser-based utilities that solve the small everyday tasks people repeatedly search for: converting units, formatting code, calculating loan payments, generating QR codes, compressing files, checking SEO basics, and dozens more. Instead of installing software or signing up for yet another account, you open a page, get your answer, and move on.
Private by design
The large majority of these tools run entirely in your browser. When you format JSON, convert a measurement, or calculate a budget, the work happens on your own device and nothing you type is sent to a server. A handful of tools that genuinely need a backend, such as PDF conversion or live currency rates, process your request on our server and discard it afterward. We never sell your data, and ads never have access to what you enter into a tool.
What you will find here
Tools are organised into clear categories so you can find what you need quickly:
- Developer tools for encoding, formatting, validating, and generating.
- Calculators for finance, percentages, and everyday math, each showing its formula.
- Converters for units, data sizes, number bases, and time zones.
- SEO tools for meta tags, readability, sitemaps, robots.txt, and structured data.
- Document tools for PDFs, Word files, and images.
- Generators, health calculators, eCommerce tools, and productivity timers, with more added regularly.
Fast, free, and no signup
Every tool loads quickly, works without an account, and is free to use. The site is kept free by unobtrusive advertising, which means you get genuinely useful utilities with no subscription. Browse the categories above to get started, or jump straight to one of the popular tools.
