Markdown to HTML is clean, since every Markdown construct has an HTML equivalent. The reverse is lossy by nature — HTML can express things Markdown cannot, so inline styles, custom attributes, nested tables and arbitrary divs get simplified or dropped. Expect a faithful text structure rather than a byte-perfect round trip.
Standard CommonMark-style syntax plus the common extensions people expect — tables, fenced code blocks and strikethrough. Platform-specific additions like GitHub task lists or footnotes vary in support across renderers, so if output must match one platform exactly, check it there before publishing.
Usually to migrate content. Pulling posts out of a CMS, moving a site to a static generator, or getting web copy into a docs repo all work better in Markdown, which is readable, diffable in git, and free of presentational markup you would otherwise have to strip by hand.
Yes, Markdown ↔ HTML Converter is completely free. No signup, no account, and no watermark on outputs. A Pro tier is available for 100 AI ops/day and larger file sizes.
Markdown ↔ HTML Converter runs entirely in your browser. Your file is never uploaded — it is read, processed and saved locally, so it never reaches our servers or anyone else's. You can disconnect from the internet after the page loads and it still works.
Direction
Markdown → HTML: Powered by a spec-compliant Markdown parser, this produces standard HTML for headings, emphasis, lists, links, images, code blocks, blockquotes, and tables — ready to paste into a page or CMS.
HTML → Markdown: Turns common HTML back into readable Markdown: headings, bold/italic, links, images, inline and fenced code, lists, blockquotes, and rules. Very deeply nested or unusual markup may need a little manual cleanup.
Round-trip friendly: Use it to migrate content between systems, clean up messy HTML from a WYSIWYG editor, or prepare Markdown notes for a static site — without copy-pasting into an online editor that uploads your text.
Privacy: Everything runs on plain JavaScript in your browser. Your content never leaves the page and the tool works offline.
