Ghostscript + QPDFHOW TO CONVERT HTML → MD
Upload your HTML
Drop the document onto the uploader. We transfer over HTTPS and keep the file in an isolated processing container.
Render with LibreOffice
LibreOffice opens the HTML headlessly and writes it as MD with styles, tables and images mapped across.
Download the MD
The MD is ready to download; typography, pagination and embedded assets match what you saw in the source.
HTML was designed to describe how a document looks inside a browser: it carries presentation attributes, inline CSS, JavaScript blocks, navigation menus, footers, cookie banners, and comment nodes that have nothing to do with the document's actual text. Markdown was designed for exactly the opposite purpose: a plain-text source that a human can read without rendering, that compiles back to clean HTML when needed. The conversion from HTML to Markdown is therefore a deliberate stripping operation. You start with a full document object model and you ask: what is the semantic content here, and what is the wrapping noise? A developer who maintains documentation in a CMS, a technical writer who pulled a web page through wget, or an author who wants to store content in a Git repository will all reach for this conversion for the same underlying reason: they need the text to outlive the renderer and become editable without a browser.
Why convert HTML to MD
The dominant real-world driver is moving web content into a static-site generator, a Git-backed wiki, or a documentation platform such as MkDocs, Docusaurus, or GitHub Wikis, all of which expect Markdown source files. A secondary driver is LLM pipelines: language models perform noticeably better on Markdown-structured text than on raw HTML because the token sequence is shorter and semantically denser. A third case is portability — Markdown files open meaningfully in any text editor, travel well through email and Slack, and do not depend on a browser engine to be human-readable.

HTML vs MD — Strengths and limitations
What each format does best, and where it falls short.
HTML Strengths
- Universal — every browser, OS, email client, and document reader displays HTML.
- Plain text, human-readable, grep-able, and diffable in git.
- Flexible — pages render even with broken or partial markup (error-tolerant parser).
- Carries structure, styling (CSS), and behavior (JavaScript) in one file.
- Accessibility-friendly when written with semantic tags and ARIA attributes.
Limitations
- Error tolerance allows sloppy markup to hide real bugs.
- Rendering depends on browser engine — pixel-perfect cross-browser output is an art form.
- Security-sensitive — unsafe HTML can execute scripts or leak data (XSS vulnerabilities).
MD Strengths
- Readable as plain text even before rendering — fits in version control beautifully.
- Dead-simple: 90% of needs covered in 10 minutes of learning.
- Converts trivially to HTML, PDF, EPUB, and DOCX via Pandoc.
- Every modern IDE, note-taking app, and developer tool renders it natively.
- Lightweight — a typical Markdown file is kilobytes, not megabytes.
Limitations
- No formal authoritative spec — CommonMark, GFM, and MultiMarkdown differ on edge cases.
- Tables and complex layouts are clunky; footnotes and math require extensions.
- Links to images stay external — no embedded media unless you base64-inline.
Quality & Compatibility
Lossless elements: block-level structure (headings h1–h6 map to # through ######), bold and italic spans, ordered and unordered lists, blockquotes, fenced code blocks (pre/code), hyperlinks (href and link text both preserved), and image references (src and alt text). Elements lost without replacement: inline CSS, class and id attributes, HTML comments, data-* attributes, colspan/rowspan in tables (Markdown tables have no merged-cell syntax, so complex tables flatten or break), form elements, iframes, and embedded scripts. Tables convert only if they are simple grids; anything with multi-row headers or merged cells requires manual post-editing. Non-semantic wrappers such as div and span are silently dropped. Character encoding is normalised to UTF-8; HTML entities such as &, <, and — are decoded to their Unicode equivalents.
Tips for Best Results
- Audit your tables before converting: any HTML table that uses colspan, rowspan, or thead with multiple rows will not survive as valid Markdown and will need manual restructuring after the conversion.
- If your HTML includes a full page shell — doctype, head, nav, footer, script tags — run the conversion on the main content element only rather than the whole file; the converter will otherwise include sidebar and navigation text as body content in the Markdown output.
- Code blocks inside pre tags are preserved correctly only when the original HTML uses both pre and code together as pre followed by code; a pre tag without an inner code tag may be treated as preformatted text and indented with four spaces instead of being wrapped in triple backticks, which can break syntax highlighting in downstream renderers.
Frequently Asked Questions
Yes, as long as the fonts are standard (system fonts or common office fonts like Arial, Calibri, Times, Helvetica). Custom corporate fonts survive if they are embedded in the source document; otherwise the conversion substitutes the closest available match, which can shift line breaks by a character or two.
Yes. Inline images are embedded into the MD at full resolution, editable tables become native MD tables, and hyperlinks keep their URLs. Complex features unique to HTML — macros, form fields, track-changes — are mapped where an equivalent exists in MD and flattened into static content otherwise.
All uploads go over TLS, files are processed in isolated containers and both the source and the output are deleted within two hours. No account is required, file contents are never indexed or used for training, and the paid plan adds a signable data-processing agreement for regulated workflows.
HTML Document
Source formatHTML is the standard markup language for web pages. As a conversion target or source, it carries text content with structural and formatting information that can be extracted or repurposed.
Markdown
Target formatMarkdown is a lightweight markup language that uses plain text formatting syntax. It is widely used in software development, technical documentation, and content management systems.

Common Use Cases
Share across platforms
Send MD files to anyone without worrying about whether they have the right software for HTML.
Embed in documents
Drop MD output into Word, Google Docs, PowerPoint, Notion or a website without conversion warnings.
Optimize size
MD often produces smaller files than HTML for web, email and storage.
Archive & future-proof
Store in a widely-supported format that will still open on future operating systems without legacy plugins.
