What HTML to Markdown Converter does, with a checked example

HTML to Markdown Converter handles both sides of a publishing handoff. Paste HTML to turn headings, paragraphs, emphasis, links, lists, quotations, and code markup into Markdown, or switch direction to turn Markdown into HTML. The generated text and live preview update with the source, making it possible to compare syntax with rendered structure before copying. The common surprise is that conversion is not a lossless round trip. Markdown has no general notation for every HTML element, attribute, class, inline style, or layout, so presentation-specific information may not survive.

Worked example

A concrete input and expected output from the current implementation.

Input

<p>Hello, reader.</p>

Expected output

Hello, reader.

In HTML-to-Markdown mode, the paragraph tags supply block structure but do not appear in Markdown. With one plain paragraph, the visible text is therefore the complete result.

How the result is produced

HTML to Markdown

The HTML-to-Markdown direction interprets tags as structure. Paragraphs become Markdown blocks; headings, emphasis, links, lists, quotations, and code use their corresponding Markdown forms when one exists. Text content is preserved as content rather than copied with its surrounding tags. Since HTML can express structures and attributes outside Markdown's model, the converted text should be reviewed wherever the source depends on styling, custom elements, or metadata.

Markdown to HTML and preview

The Markdown-to-HTML direction interprets Markdown punctuation and block layout, then produces HTML elements for the recognized structure. The live preview lets you inspect the rendered result while editing either source direction. Processing stays in the browser, so the pasted HTML or Markdown is not uploaded. The preview reflects this converter's interpretation; it does not promise the same rendering on a site with different CSS or Markdown rules.

Good uses

Convert a CMS article fragment containing headings, links, and lists into Markdown for a repository README or a Markdown-based publishing system.
Generate HTML from a small Markdown announcement and inspect its live rendering before placing the generated markup in an email or page template.
Strip ordinary paragraph and emphasis tags from copied HTML so editors can review the same content as compact, version-control-friendly Markdown.

Limits and checks

HTML classes, ids, data attributes, inline styles, scripts, forms, and layout containers do not all have Markdown equivalents. A readable conversion may still omit source information needed by the original page.
Markdown has dialects. Tables, task lists, strikethrough, automatic links, and raw HTML can be recognized differently elsewhere, even when this tool's preview looks correct.
Generated HTML is a conversion result, not proof that pasted content is safe to publish. Review untrusted links, embedded HTML, and any markup before inserting the output into a website.

Common questions

Will it preserve my CSS classes and inline styles?

No, not in a general HTML-to-Markdown conversion. Markdown can describe common document structure but does not encode arbitrary CSS declarations, classes, ids, data attributes, or interactive behavior. If those details matter, retain the original HTML and compare it with the converted Markdown. Treat the output as a content-oriented representation, not as a backup of the source markup.

Can I convert HTML to Markdown and back without changes?

No. Even when the visible content remains equivalent, the return trip can use different tags, whitespace, escaping, or Markdown marker choices. Information with no Markdown representation may already have been lost on the first conversion. Use the preview to check structure and appearance, but compare source and output directly if exact attributes or HTML serialization matter.
