The Complete Guide to HTML & Markdown Conversion

Writing content for the web has changed dramatically. HTML is the language of browsers, but it is verbose and hard for humans to read and edit. Markdown is the opposite: designed to be written and read as plain text, then compiled to HTML on demand.

When Should You Convert HTML to Markdown?

  • Migrating a CMS: Moving content from an HTML-based platform (like legacy WordPress pages) to a Markdown-based one (Ghost, Astro, Hugo) requires converting HTML to Markdown first.
  • Writing documentation: GitHub READMEs, GitBook docs, and most developer wikis use Markdown. Converting your HTML source makes it immediately portable.
  • Version control: Markdown diffs cleanly in Git. Raw HTML diffs are a mess. Storing content as Markdown makes collaborative editing far easier.

GitHub Flavored Markdown (GFM) Support

This tool uses the Turndown library with the GFM plugin, giving you support for:

  • Fenced code blocks (```language)
  • HTML tables -> GFM pipe tables (| col | col |)
  • Strikethrough (~~text~~)
  • Nested lists, blockquotes, and inline code

When Should You Convert Markdown to HTML?

Switch the tool to Markdown -> HTML mode when you need to paste formatted content into a raw HTML email template, a legacy system that only accepts HTML, or when you want to preview how your Markdown will render.
