About Toolzmint
Toolzmint is a free collection of browser-based utility tools for developers, writers, and anyone who needs to get a small task done quickly, without installing software or creating an account.
Who builds Toolzmint
Toolzmint is an independent project built and maintained by Dhanunjaya Lakshmi G., a full-stack JavaScript developer (React, Next.js, Node.js) based in Hyderabad, India. I started it in March 2026 and write the code, the tool guides, and the blog posts myself.
The site is not run by a company or a content team. When you send a message through the contact page, it comes straight to me.
You can find me on GitHub, and the source code for Toolzmint is public, so you can see exactly how every tool works.
Why I built it
Many small tasks, like formatting JSON, decoding a JWT, removing line breaks from copied text, or generating a UUID, send you to websites full of pop-ups, sign-up walls, or tools that upload your input to a server. I wanted one clean place where these tasks take a few seconds and your data stays on your device.
What you will find here
Toolzmint currently has 34 tools covering text editing, developer utilities, generators, encoders, converters, and calculators. They include a word counter, line break remover, JSON formatter, UUID generator, regex tester, password generator, and image resizer. You can browse all of them on the tools page.
The blog explains the ideas behind the tools, such as what a UUID is, how Base64 and URL encoding work, and how to write regular expressions.
Privacy by design
Every tool runs entirely in your browser. The text, files, and images you enter are processed on your device and are never sent to a Toolzmint server. That matters for things like JWT tokens, hashes, and passwords, which should never be pasted into a site that uploads them. Read the privacy policy for details.
How the site is built
Toolzmint is built with Next.js, React, and Tailwind CSS. Every page is generated ahead of time so it loads fast, and each tool works without a server. It supports light and dark themes and works on phones as well as desktops.
How Toolzmint stays free
All tools are free to use, with no account and no usage limits. To cover hosting and development, Toolzmint may show a small number of ads, placed so they never get in the way of using a tool.
Suggest a tool
New tools are added and existing ones improved regularly. If there is a tool you need, or something does not work the way you expect, let me know.
