Convert Markdown to HTML

Why convert Markdown to HTML?

Markdown is pleasant to write, but browsers, email editors and many CMS fields only understand HTML. Converting turns each piece of Markdown syntax into the matching tag: # Title becomes <h1>, a line starting with - becomes a list item, [text](url) becomes a link, and so on.

This tool uses marked with GitHub-Flavored Markdown, so it supports the extras people use every day: tables, task lists with checkboxes, ~~strikethrough~~ and URLs that turn into links automatically. You can choose to treat single line breaks as <br>, the way GitHub comments do, instead of joining them into one paragraph as standard Markdown does.

The output can be an HTML fragment, ready to paste into a CMS, a template or an email, or a complete HTML document with basic styles that you can open directly in a browser. A rendered preview appears next to the code so you can check the result. The preview is sanitized with DOMPurify, so scripts in the Markdown do not run.

Because the HTML is generated by a standard GitHub-Flavored Markdown parser, it is predictable: plain semantic tags without classes or inline styles, which you can style with your own CSS or paste into any editor that accepts HTML. The conversion happens in your browser and your text is not uploaded. You get one free try per tool: one file or one pasted text. After that you can still re-process the same text with different options, but new input needs ToolStudio Pro, which gives unlimited use of every tool, several files at once downloaded together in a ZIP, and no ads. You can cancel anytime.

What people use it for

• Publishing a README or documentation page as a web page.
• Pasting formatted content into a CMS or email editor that only accepts HTML.
• Turning notes from Obsidian or another Markdown editor into a shareable page.
• Generating HTML tables from Markdown tables.
• Checking how a Markdown file will render before committing it.

Fragment or full document?

A fragment contains only the converted content (<h1>, <p>, <ul>...) and is what you want when the HTML goes inside an existing page, template or editor. A complete document adds <!doctype html>, <head> with a title and basic styles, and <body>, so it can be saved as an .html file and opened on its own.
