What is Markdown to HTML Converter?
Markdown to HTML Converter takes text written in Markdown , a lightweight plain-text formatting syntax , and converts it to the equivalent valid HTML. Markdown was created by John Gruber in 2004 as a way to write structured content (headings, lists, bold, links, code) using simple punctuation, with the expectation that it would be converted to HTML for publishing.
Today, Markdown is the standard format for README files (GitHub), documentation (Notion, Confluence), blog posts (Ghost, Jekyll, Hugo), static site generators, and developer-focused content management systems. The conversion from Markdown to HTML is a standard step in nearly every modern content publishing pipeline.
This tool handles the complete CommonMark Markdown specification including: headings (# H1 through ###### H6), bold (**text**) and italic (*text*), ordered and unordered lists, links ([text](url)), images (), inline and fenced code blocks with syntax highlighting, blockquotes, horizontal rules, and GitHub Flavored Markdown tables.

A technical writer exports Markdown content from a notes app to HTML for pasting into a CMS or email newsletter builder.
A blogger writes in Markdown for speed and uses the converter to review the final HTML before publishing to a platform that accepts raw HTML.

Markdown to HTML Converter FAQs
Quick answers about the workflow, privacy, and where this tool fits in a broader job.
What Markdown flavors does this support?
This converter follows the CommonMark specification, which is the most widely adopted Markdown standard. It also supports GitHub Flavored Markdown (GFM) extensions including tables, task lists, and strikethrough.
Can I convert HTML back to Markdown?
This tool converts Markdown to HTML. For the reverse , HTML to Markdown , you would need a dedicated HTML-to-Markdown tool, which handles the reverse parsing step.
Does the converter support syntax highlighting for code blocks?
The converter outputs the HTML structure for fenced code blocks with the language class (e.g., class='language-javascript'). Actual syntax highlighting requires a JavaScript library like Prism.js or highlight.js applied to the rendered HTML.
Why does my Markdown look different in different apps?
Markdown has several flavors (CommonMark, GFM, MultiMarkdown) that support different extensions. A table or task list written in GitHub Flavored Markdown may not render in a basic CommonMark parser.
How do I add a table in Markdown?
Use pipes and hyphens: | Header 1 | Header 2 | on one line, then | --- | --- | on the next, then data rows below. This converter will render the Markdown table as an HTML <table> element.
