About toolpermarket

toolpermarket is a growing collection of free online utilities, built to do one job each, quickly, and get out of your way.

What we believe

Most "free online tool" sites are slow, buried in pop-ups, and quietly upload whatever you paste into them. We wanted the opposite: small, focused tools that load fast and respect your data. Every tool on this site is a single page that does a single thing, so the URL you land on is exactly the tool you need.

Our principles

• Runs in your browser. The overwhelming majority of our tools process your input locally with JavaScript. Your text, numbers, and images are handled on your device and are not sent to a server.
• No account required. Nothing to sign up for, nothing to install. Open a tool and use it.
• One tool, one page. Each utility is self-contained, with a short how-to and an FAQ so you can get the result and understand it.
• Fast and lightweight. Minimal design, no heavy frameworks, no auto-playing anything.

What you will find

The library is organized into categories that grow over time:

• Calculators — everyday math and health: age, BMI, percentage, tip, loan, dates, and more.
• Converters — length, weight, temperature, data size, speed, and number bases.

How we keep it free

toolpermarket is free to use. To keep every tool open to everyone without paywalls or sign-ups, we plan to support the site with advertising in the future. When ads are enabled, we will keep them unobtrusive and out of the way of the tool you came to use. For details on how advertising will affect data and cookies, see our Privacy Policy.
