GitHub-flavored Markdown via marked
How the markdown to html converter works
Conversion uses marked, one of the standard Markdown parsers in the JavaScript ecosystem, with GitHub-flavored extensions, tables, fenced code blocks and autolinks behave the way GitHub renders them. The output is an HTML fragment ready to paste into a page, CMS field or email template. Each construct maps to its semantic tag: # heading becomes <h1>, ## becomes <h2>, **bold** becomes <strong>, a - list becomes <ul><li>, a numbered list becomes <ol>, and [text](url) becomes an <a href>. A blank line separates paragraphs into <p> elements, so leaving lines unseparated merges them into one paragraph.
The output is a fragment by design, no <html> or <body> wrapper, because the common destinations (CMS bodies, email builders, static-site partials) want exactly that. If pasting into an email tool, remember most of them strip <style>; inline styling has to come from the destination side.
Frequently asked questions
Which Markdown flavor is supported?
GitHub-flavored Markdown via marked: standard CommonMark plus tables, fenced code blocks, strikethrough and autolinks, matching what GitHub, GitLab and most docs tools render.
Why is there no <html> or <head> in the output?
Deliberately, a fragment pastes cleanly into CMS fields, templates and partials. Wrap it yourself only when creating a standalone file.
Is the HTML sanitized?
Raw HTML inside your Markdown passes through, per Markdown spec. Only convert trusted input if the output will be rendered on a site, the same rule as any Markdown pipeline.
Do code blocks keep their language?
Fenced blocks emit <code class="language-x">, highlight.js/Prism pick that up on the destination page for syntax coloring.
Why did two lines of text merge into one paragraph?
Markdown treats a single line break as a soft wrap, not a new paragraph. It needs a blank line between blocks. To force a line break inside a paragraph without a blank line, end the first line with two trailing spaces, which marked converts to a <br>.
Is the conversion reversible?
Broadly yes, the HTML-to-Markdown tool goes the other way, but it is not guaranteed byte-for-byte, because HTML can express structure and attributes Markdown has no syntax for. Headings, lists, links and emphasis round-trip reliably; heavily styled HTML does not.
Is my content uploaded?
No, parsing is local; drafts stay on your machine.
