Markdown preview

Type Markdown on the left and see it rendered on the right as you go. When it looks right, copy the HTML.

It renders a safe subset: headings, bold, italic, code, links, lists, quotes and rules. Everything you type is escaped first, so nothing in the source can run in the preview.

A subset: headings, bold, italic, code, links, lists, quotes and rules. Enough for a readme, not a full engine.

Questions

Is what I paste sent anywhere?
No. Every tool in this kit runs in the page itself. There is no server here that receives what you paste, and you can check it in your browser's network tab: using a tool produces no request carrying your input at all.
Which Markdown does it support?
The common core: headings, bold and italic, inline code and fenced code blocks, links, unordered and ordered lists, blockquotes and horizontal rules. It is a subset for readmes and comments, not a full engine with tables and footnotes.
Is the preview safe?
Yes, by construction. Every character you type is HTML-escaped before anything else happens, and the renderer only ever emits a fixed set of tags. A script tag in your source shows up as text, not as a running script, and a javascript: link is left as plain text rather than made clickable.
Can I copy the HTML?
Yes. The Copy HTML button gives you exactly what the preview shows, ready to paste into a page. There is also a button to copy the Markdown back.
Does it support tables?
Not yet. Tables and other extended syntax are outside this subset. For a readme, a comment or a description, what is here covers it.
