HTML to Markdown
Convert common document structure into Markdown you can revise.
Runs in your browser. Nothing is uploaded.
Make HTML easier to edit as Markdown
HTML to Markdown turns common HTML documents into Markdown text. Paste markup into the input area, load the sample, or drop an HTML file, then press Convert. The result stays as plain text in the output editor so you can review the exact headings, links, lists, and code blocks before copying it into a README, issue, note, or content repository.
The converter uses Turndown in the browser. It handles headings, paragraphs, emphasis, strong text, links, ordered and unordered lists, block quotes, inline code, fenced code blocks, and ordinary tables as a practical starting point. Markdown has fewer layout controls than HTML, so a visual match is not the goal. The goal is readable source that preserves the document's main structure.
Expect a content conversion, not a pixel copy
HTML can contain CSS classes, inline styles, responsive layout rules, embedded media, and custom elements that have no direct Markdown equivalent. Those details may be omitted or simplified. Review images and links, especially when the source contains relative URLs. A table may need manual cleanup when cells contain complex markup or multiple paragraphs. If you need to normalize the original markup first, use HTML Formatter.
This is a focused converter rather than a full content management system. It does not publish a page, fetch remote assets, or preview the result in a sandbox. It does not run scripts from the input. For the reverse workflow, use Markdown to HTML and inspect the HTML text before placing it into a template. Text Diff can help compare an original and revised conversion.
Review before using converted Markdown
Markdown parsers differ in their handling of raw HTML, tables, line breaks, and extensions. The output is compatible with common GitHub-flavoured Markdown conventions, but the final repository or publishing system still decides how it will render. Check heading levels, list nesting, link destinations, code language labels, and any raw HTML that remains. The output can be copied or downloaded as converted.md.
Private, local conversion
Turndown reads the pasted text or local file in your browser. The page does not send the HTML to an API and TheDevTab does not receive your document. Browser downloads create a local file through an object URL, which is revoked after the download starts. Keep reviewing content for secrets and personal data before sharing the Markdown. JSON users can also work locally with JSON Formatter or JSON to YAML.
FAQ
Will converting HTML fetch assets or upload the markup?
Turndown receives only the markup string in your browser, so it does not fetch images, stylesheets, or linked pages. The HTML is never uploaded, and asset URLs are copied into the Markdown as references.
What HTML elements convert well?
Headings, paragraphs, links, emphasis, lists, block quotes, inline code, and fenced code blocks usually convert into readable Markdown. Complex layout, custom elements, and table presentation need a review after conversion.
Will CSS styles be preserved?
No. Markdown does not represent most CSS layout and style rules, so classes, inline styles, and complex presentation are not carried over as equivalent Markdown. The document's text and supported structure are converted separately from its visual styling.
What happens to links and images?
Links and images are represented as Markdown references using their existing destination URLs and image attributes where Turndown supports them. The converter does not verify or download those destinations.
Is the result guaranteed to look identical?
No. The output preserves supported document structure rather than pixels or CSS layout. Markdown renderers can also differ in tables, line breaks, raw HTML, and extensions.
How do I convert the Markdown back to HTML?
Use Markdown to HTML for the reverse direction, then inspect the generated HTML text. The two conversions are practical text transforms and do not restore styling or structure that Markdown cannot express.
