Hi, I'm Muhammad Usman.I build MDTool.
Software developer · Agentic AI, mobile & web development
I work on browser-based document processing and web tooling. I write every converter and every guide on this site, and the recommendations in the blog are based on the tools' documented behavior and hands-on testing.
MDTool is an independent, solo-maintained project. That's also why it can stay free: there is no team, no office, and no server infrastructure processing your files.
The tools
What MDTool is
A small set of single-purpose conversion tools. There is no account system, no saved-document history, and no paywall. Every tool is free to use without limits.

How conversion actually works
Your files stay on your device
Every conversion runs entirely in your browser using JavaScript. When you paste text or upload a file, it is parsed and rendered locally on your device. It is never transmitted to an MDTool server.
Verify it yourself
Open your browser's Network tab while converting, and you'll see no outbound request carrying your document content.

How MDTool is built and tested
Parsing, rendering, and file generation all happen on your device; there is no conversion server and no upload step. Each tool is built on well-established open-source libraries, none of which needs a server round-trip to do its job.

How it's built and tested
- These are the dependencies listed in the project's package.json, and the site's code and change history are public on GitHub.
- The guides are based on each tool's documented behavior and hands-on testing of the converters.
- The facts on this page are checked against the current code.
