About the Markdown to HTML Converter
This Markdown to HTML converter turns Markdown text into standard HTML, showing a live rendered preview alongside the raw HTML output so you can check the result looks right before copying it. It supports GitHub-flavoured Markdown extensions — tables, strikethrough, task lists and automatic linking of bare URLs — and runs entirely in your browser, so nothing you write is uploaded anywhere.
How to use the Markdown to HTML Converter
- 1
Type or paste your Markdown into the input box; a starter example is there to replace.
- 2
Toggle GitHub-flavoured Markdown on or off depending on which extensions your target platform supports.
- 3
Check the rendered preview to confirm headings, lists and links look right.
- 4
Copy or download the HTML output from the code panel underneath.
What people use it for
Preparing content for a CMS
Many content management systems accept raw HTML but not Markdown directly. Write in Markdown for speed, then convert to HTML for the final paste.
Checking a README before committing
See exactly how a README.md will render before pushing it, catching a malformed table or a broken link early.
Converting notes for email or a wiki
Turn a Markdown draft into HTML that pastes cleanly into an email client or a wiki editor that expects formatted HTML rather than Markdown syntax.
What GitHub-flavoured Markdown adds
Standard Markdown, as originally specified, covers headings, emphasis, lists, links and code blocks. GitHub-flavoured Markdown, universally referred to as GFM, layers on pipe-delimited tables, strikethrough text using double tildes, automatic linking of any bare URL without needing bracket syntax, and task list checkboxes written as a hyphen followed by an empty or checked bracket. GFM is now the de facto standard well beyond GitHub itself, used by GitLab, most static site generators and the majority of developer documentation tools, which is why it is the default here.
Why single line breaks disappear by default
The original Markdown specification treats a single line break within a paragraph as insignificant, collapsing it to a single space, and only starts a genuinely new paragraph after a blank line. This surprises people used to word processors, where every Enter key press starts a new visual line. Turning on 'Treat single line breaks as br' switches to the behaviour some chat platforms and comment systems use instead, preserving every line break exactly as typed, at the cost of no longer matching how most Markdown files and READMEs are conventionally written.
Tips
- Leave a genuinely blank line between paragraphs — a line that only looks blank but contains trailing spaces will not start a new paragraph in some renderers.
- Fenced code blocks, three backticks on their own line, survive conversion more reliably than indented code blocks.
- If pasted HTML looks broken in the preview, check for an unclosed link or an unmatched formatting character such as a stray underscore.
