What this site is

OnlineMiniTools brings 2,400+ small tools into one catalog so you can finish a task and move on. Every tool is free to use, and none of them require an account or a subscription. The catalog is organized by category, with search and related-tool links to help you find the right utility quickly.

Who runs it

OnlineMiniTools is an independent project created and maintained by Prajwal, a software developer. The person who builds the tools also writes the guides, maintains the site, and answers support email.

For questions, corrections, or partnership requests, email [email protected] or use the contact form.

How tools are chosen and built

Many tools start as a visitor request, while others come from common search queries and everyday tasks. Each tool is built around a single job, tested on its main workflow, and published with a short guide where one helps. New tools are added regularly, and existing tools are updated when behavior or browser support changes.

How the site stays free

OnlineMiniTools is ad-supported. Advertising helps cover hosting, domain, and development costs. Ads never gate access to a tool, and there is no paid tier or credit system. If an ad ever interferes with a tool, report it through the contact form and we will look into it.

Privacy and accuracy

Whenever a tool can run in the browser, it does. That keeps your input on your device instead of sending it to a server. Tools that need a server are described as such on their pages. For details about analytics, advertising, and cookies, see the Privacy Policy.

We test tools before publishing, but no calculator or converter is a substitute for professional advice. Verify critical results independently and read the Disclaimer for the limits of what the site can promise.

Corrections and feedback

If a tool gives a wrong result, a page has an error, or a guide needs an update, email [email protected] or use the contact form. Include the tool name and, when possible, the input you used so the issue can be reproduced.
