Who We Are
A-Z Super Utility is an independent, one-person project created to bring together the everyday online tools people search for most - all in a single, fast, ad-light website. Instead of visiting a different site for a BMI check, a loan EMI, a QR code, a JSON formatter, or the day's Thirukural, you can find them all here, organised A to Z.
Why We Built It
Most "free tool" websites are slow, cluttered with pop-ups, demand sign-ups, or quietly harvest the data you type in. We wanted the opposite: tools that load quickly, work on any phone or laptop, and respect your privacy. That principle shapes every page - the calculators and converters do their work directly in your browser, so the numbers and text you enter usually never leave your device.
What You'll Find
Our library spans 170+ tools across 18 categories, including:
- Finance - EMI, SIP, mortgage, income tax, GST, compound interest, and more.
- Health & Fitness - BMI, BMR, calorie, body-fat, pregnancy, and sleep calculators.
- Math & Calculators - percentages, fractions, statistics, quadratic equations, prime numbers.
- Developer & SEO - JSON tools, JWT decoder, regex tester, meta-tag and schema generators.
- Text & Image - counters, case converters, and image/PDF conversion and compression.
- Weather, World & Tamil - live weather, air quality, country facts, Thirukural, and Tamil tools.
- AI & Entertainment - an AI assistant, content helpers, trivia, and more.
Our Commitment to Privacy
We designed the site to collect as little as possible. Client-side tools process your input locally; preferences like your theme and favourites are stored only in your browser. Where a tool must call an external service (for example, weather or currency data), we send only the minimum query needed. You can read the full details in our Privacy Policy.
How the Site Is Supported
A-Z Super Utility is free to use. To cover hosting and development costs, we display a limited number of ads. This lets us keep every tool free and available without a paywall or subscription.
