Frequently asked questions

Is the rendered HTML safe?+

Yes. The Markdown is parsed to HTML and then run through DOMPurify, a well-established sanitization library, before it’s inserted into the page — script tags and other unsafe markup are stripped.

Which Markdown features are supported?+

Standard Markdown: headings, bold/italic, links, images, lists, blockquotes, code blocks and inline code, and tables.

Is my Markdown uploaded anywhere?+

No. Parsing, sanitizing and rendering all happen entirely in your browser — nothing is sent to a server.
