Converts Markdown to the HTML a renderer would produce, with GitHub Flavored Markdown enabled by default — tables, task lists, strikethrough and autolinking all work. Useful when you need to paste formatted content into a system that only accepts HTML, or to check exactly what markup your Markdown becomes.
How it works
- Conversion runs in your browser on marked, a CommonMark-compliant parser.
- GFM adds tables, task lists, strikethrough and autolinks; CommonMark mode turns them off.
- Output is returned as HTML source text, not rendered, so you can inspect and copy it.
Where your data goes
Nowhere. This tool runs entirely in your browser: the text you paste is processed by the page and is never transmitted to a server or written to a log.
When a run costs points, a one-line summary is saved to your own history so you can find it again. The summary records the shape of the run — sizes, counts, the values you looked up — never the content you pasted.
What it costs
Free up to 50.0 KB per run without an account. Past that, a run costs 1 points and is saved to your history.
Points come from signing up, checking in daily, commenting and completing your profile.

- Is the output safe to insert into a page?
- Not on its own. Markdown permits raw HTML, so anything a user wrote passes straight through. Sanitize the output server-side before rendering anything you did not write yourself.
- Why does my line break disappear?
- CommonMark treats a single newline as a space. Use a blank line for a new paragraph, two trailing spaces for a hard break, or turn on the line-break option to make every newline a <br>.
- What is the difference between GFM and CommonMark?
- CommonMark is the strict specification. GFM adds the extensions GitHub uses. If your target renders on GitHub, GitLab or most documentation tools, GFM is the right choice.
The open-source behind it
This tool runs on markedjs/marked, released under MIT. If you need the same behaviour inside your own program, that is the library to reach for.
