How to Convert Markdown to HTML (and Back Again)

Markdown and HTML both show up constantly in the same workflows — a README that needs to become a web page, HTML copied from somewhere that needs to turn into clean Markdown for a wiki, a note that needs previewing before it's committed anywhere. Needing to go one direction today and the other tomorrow is normal, which is why a one-way converter is only ever half useful.

Both Directions, One Tool

QR Ivify's Markdown ⇄ HTML Converter converts either way, with the result updating live as you type. Going from Markdown, you can toggle between a rendered preview and the raw HTML source. Going from HTML, you get clean Markdown out, ready to paste into a README or wiki.

Step by Step

1. Choose a direction — Markdown → HTML or HTML → Markdown.
2. Type or paste your source into the left box.
3. The converted result updates live on the right — toggle between a rendered preview and the raw HTML source for the Markdown → HTML direction.
4. Copy the result or download it as a file.

GitHub-Flavored Markdown, Both Ways

Tables, strikethrough, task lists, and autolinks all convert correctly in both directions — not just the basics. That matters for anything coming from or going to GitHub, since plain Markdown parsers often drop these.

Any HTML involved — whether typed directly or produced from Markdown — is sanitized before it's ever rendered or converted, so pasting in HTML from an untrusted source is safe: script tags and event handlers are stripped before anything happens with it.

Frequently Asked Questions

Does this upload my content anywhere? No. Conversion happens entirely in your browser using marked and turndown — nothing is sent to a server.

Does this support GitHub-flavored Markdown? Yes — tables, strikethrough, task lists, and autolinks all convert correctly in both directions.

Is the preview safe if I paste in HTML from an untrusted source? Yes — all HTML (whether typed directly or produced from Markdown) is sanitized with DOMPurify before it's ever rendered or converted, so script tags and event handlers can't execute.

Will converting back and forth give me my exact original text back? The structure and formatting round-trip correctly, but not necessarily byte-for-byte — things like exact whitespace or list-marker style can come out slightly different.
