How Markdown ↔ HTML works

Convert Markdown to HTML and HTML back to Markdown for docs, blogs, and content workflows. Runs locally in your browser.

  1. 1. Add input. Paste, type, or upload. Use a sample if you just want to see it work.
  2. 2. Run it. Processing happens in the browser.
  3. 3. Copy or download. Take the output and close the tab.

Is GitHub-flavored Markdown supported?
Markdown → HTML uses GFM via the marked parser. HTML → Markdown covers common tags.

ToolBay does not store your input. Close the tab and it is gone. More text tools.
