Markdown to HTML Converter
Supports common elements (headings, bold/italic, links, code, ordered/unordered lists, blockquotes) in both directions — automatically escapes any HTML tags found inside Markdown input to prevent code injection, and runs entirely in your browser with nothing ever uploaded to a server.
The text is processed entirely on your device and is never sent to any server.
Supports common elements (headings, bold/italic, links, code, lists, blockquotes) — not the full Markdown or HTML specification.

What this tool does
Converts between Markdown and HTML in both directions, so content can move between a system that writes Markdown and one that expects HTML.
When to use it
- Content written in Markdown that a platform needs as HTML.
- HTML you want as Markdown for a repository or documentation.
- Moving articles between two different content systems.
How to use it
- Choose the direction: "Markdown to HTML" or "HTML to Markdown".
- Paste your text into the field.
- Click "Convert" and copy the "Result".
A practical example
Input
Markdown with a heading, a list and a link, converting to HTML.
Output
HTML with a heading tag, a list and an anchor, carrying the same content.
Limitations
- Supported: headings, bold and italic, links, inline and fenced code, ordered and unordered lists, blockquotes, horizontal rules and paragraphs — not the full CommonMark specification: tables, nested lists and footnotes are not covered.
- HTML to Markdown loses anything Markdown has no equivalent for, such as styles, attributes and complex elements.
- A round trip may not reproduce the original text exactly.
Privacy and processing
Both the Markdown and the HTML are processed locally; neither is sent anywhere.
Technical notes
- The converter is written inside this project rather than taken from a library, to keep the output predictable and avoid adding weight or unaudited dependencies for the sake of rare cases.
Frequently Asked Questions
No — it supports common elements only (headings, bold/italic, links, code, lists, blockquotes), not advanced features like tables or nested lists.
