About Markdown to HTML conversion

Markdown is a lightweight plain-text syntax for headings, bold, links, and lists - readable as-is, but not something a browser can render directly. Converting to HTML interprets that syntax and outputs the equivalent markup: # headings become <h1>-<h3>, **bold** becomes <strong>, and so on.

This is the standard bridge between writing in Markdown (READMEs, docs, notes) and publishing that content anywhere HTML is expected - a CMS, a static site, or an email template.

Common use cases

  • Publishing README or documentation files as web pages
  • Converting notes written in Markdown for a static site generator
  • Preparing Markdown content for a CMS that expects HTML
  • Rendering changelogs or release notes for the web
