How Convertidor HTML a Markdown Works
An HTML to Markdown Converter is a content migration utility used to reverse-engineer web markup into plain text. This tool is essential for technical writers, developers, and content strategists moving blogs from WordPress to Hugo/Gatsby, extracting documentation from wikis, and cleaning up rich-text copy.
The conversion engine handles the transformation through a DOM-walking pipeline (Turndown Service):
- Sanitization: The tool loads your HTML into a secure, inert DOM element.
- Traversal: It walks through every node in the tree.
- Pattern Matching:
- Heading:
<h1 id="title">Hello</h1>-># Hello - Emphasis:
<em>World</em>->*World* - Code:
<pre>var x = 1</pre>->var x = 1
- Heading:
- Cleaning: It removes specific "junk" tags (
<script>,<style>,<meta>) that don't belong in a Markdown document.
The History of Markdown
Writing for the web, without the tags.
- Origin (2004): John Gruber and Aaron Swartz created Markdown so writers could create HTML without writing tags.
- The Reverse Need: As Markdown became the standard for Documentation (GitHub, StackOverflow, Discord), people needed a way to get old HTML content into this new format.
- Turndown: The specific algorithm used (formerly "to-markdown") is the industry standard for this reverse conversion.
Technical Comparison: Verbosity
