How to Convert HTML to Markdown

What this HTML to Markdown converter does

HTML to Markdown conversion is useful when you have HTML content and need a Markdown-style text version for editing, documentation, or another text workflow. The converter applies built-in text transformations to selected tags, attributes, entities, and whitespace patterns. It is pattern-based, so the result depends on how closely the supplied HTML matches the supported forms.

Step-by-step instructions

1. Enter or paste the HTML code into the text input. The input is optional; if you leave it empty or omit it, the conversion completes successfully with an empty result.

2. Start the conversion using the page control. No separate formatting choices are required for the built-in transformations.

3. Review the converted text. Heading elements from <h1> through <h6> become Markdown heading prefixes while their inner text is preserved. Links with single- or double-quoted href attributes become Markdown links. Images with double-quoted src attributes become Markdown images; the matched form uses alternative text when it appears after the src attribute, and otherwise produces empty alternative text.

4. Check inline and block content. Bare strong, b, em, and i elements can become Markdown emphasis markers. An exact bare <pre><code>...</code></pre> structure can become a fenced code block, and matching bare code elements can become inline code. Certain list, blockquote, paragraph, line-break, horizontal-rule, and block-container patterns also receive Markdown-style transformations.

5. Read through the output and correct anything that did not convert as expected. Remaining matching tag syntax is removed after supported transformations, while text enclosed by those tags is preserved. Selected named entities and decimal numeric character references are decoded during conversion.

How to interpret the result

Treat the output as Markdown-style text produced from recognized patterns, not as a guaranteed representation of every HTML structure. Attributes, nesting, or tag arrangements that differ from the supported patterns may not receive their intended transformation. Script and style blocks are removed when they match the converter's case-insensitive opening and closing block patterns, but unmatched or unterminated blocks are not guaranteed to be removed.

Whitespace is normalized at the outer level: runs of four or more newline characters are reduced to three, and leading and trailing whitespace is stripped. Decimal references in the digit-only form &#digits; are sent for character conversion. Malformed forms can remain unchanged, while a digit-only value outside the valid character range can cause conversion to raise. Review the result when the HTML contains unusual attributes, nested structures, or numeric references.

Worked example

A documentation editor has a short HTML heading and emphasized note that need a Markdown-style version.

Enter <h2>Release notes</h2><p><strong>Updated</strong></p> and run the conversion.

The result contains a Markdown heading for the heading element and Markdown emphasis markers around the strong text.

Limitations

• This is a pattern-based converter, not a complete HTML parser. HTML variations that do not match supported attributes or structures may not convert as expected, even though remaining matching tag syntax is removed.
• Unmatched script or style blocks are not guaranteed to be removed, and an out-of-range digit-only decimal reference can cause conversion to raise.

Common errors

• A complex HTML element remains partly unchanged because its attributes, nesting, or tag structure does not match a supported pattern. Compare it with the recognized form, simplify the markup where practical, and review the converted text instead of assuming every variation will be transformed.

FAQ

What happens if I leave the HTML input empty?

Yes, when the input is omitted or empty, the operation completes successfully and returns an empty converted text result.

Will every HTML element convert perfectly to Markdown?

Not necessarily. The converter handles selected patterns, and variations in attributes, nesting, or tag structure may not match. Review and edit the output when the source uses unusual HTML.

How are decimal HTML character references handled?

A digit-only decimal reference in the form &#digits; is passed to character conversion. A malformed reference may remain unchanged, while a value outside the valid character range can cause conversion to raise.
