About the converter
Markdown to HTML Converter is a free public utility built by Carlos Crespo under CSolutions. It pairs a browser interface with an open-source Python CLI and library, so the same parser that renders this page's preview is available to run on your own machine.
Why it exists
Markdown is convenient for writing: plain text, easy to version, easy to read even unrendered. But websites, content management systems, and documentation platforms often need HTML, and the handoff between the two is usually opaque: paste into some black-box tool and hope. This converter makes that step visible. You can see the exact HTML your Markdown produces, inspect it before you use it, and choose whether you need a small fragment or a complete standalone document.
Who built it, and why
CSolutions builds small, focused web tools and client sites. This converter started as an internal utility for moving Markdown notes and AI-drafted content into real pages, and was cleaned up, hardened, and released publicly because the same problem is common enough to be worth sharing. It is maintained alongside CSolutions' other public work; see carloscrespo.info for the rest.
Who this is for
- Bloggers and writers moving Markdown from a note-taking app or an AI drafting tool into a CMS that expects HTML.
- Students and researchers turning Markdown notes or writeups into a single shareable HTML file, with no account or software install required.
- Developers who need a quick, escaped HTML fragment for documentation, a README preview, or a component, without pulling in a Markdown library for a one-off task.
- Small businesses producing a one-off styled page, email body, or handout from Markdown, without standing up a full site build for it.
How it's built
The parser and converter are a zero-runtime-dependency Python package: no third-party Markdown library, so the exact escaping and URL-scheme rules are visible in one place rather than inherited from an external dependency. The web interface sends Markdown to that same code running as a small serverless API, renders the result in a sandboxed preview, and never intentionally stores what you submit. See Privacy for the full data-handling picture.
