Why Convert HTML to Markdown?
HTML is designed for web-page structure and presentation, with markup for layout, styling, and interactivity. Markdown is a much simpler plain-text format, useful for documentation, README files, Git repositories, notes, knowledge bases, static sites, content migration, and text-based AI workflows.
When you convert HTML to Markdown, you keep the meaningful structure of a document — headings, lists, links, tables, emphasis — while dropping the presentation layer that doesn't belong in a plain-text file.
How to Convert HTML to Markdown
Step 1
Paste HTML or upload a file
Paste HTML source directly, or upload a local .html or .htm file from your device.
Step 2
Convert the HTML
MarkForge converts the HTML structure — headings, paragraphs, lists, links, and tables — into Markdown locally in your browser.
Step 3
Review the generated Markdown
Check the result in the Markdown or Preview tab, and edit it directly if needed.
Step 4
Copy or download the result
Copy the Markdown or download it as a .md file.
Paste HTML or Upload an HTML File
MarkForge accepts HTML two ways. You can paste HTML source directly into the text box, or upload a local .html or .htm file from your device — both use the same conversion pipeline.
Conversion happens entirely in your browser. MarkForge converts the HTML content you provide — the structure of your pasted source or uploaded file — into Markdown, and displays the result as editable plain text that you can copy or download.
Markdown files commonly use the .md extension, so converting HTML to Markdown also gives you an HTML-to-MD workflow — paste or upload HTML, then download a ready-to-use .md file.
What HTML Formatting Is Preserved?
MarkForge preserves headings, paragraphs, bold and italic text, ordered and unordered lists (including nested lists), links, blockquotes, inline and fenced code, simple tables, and basic images.
CSS styling, fonts, page layout, JavaScript, interactive widgets, and complex visual design do not have a direct Markdown equivalent and are not recreated. MarkForge focuses on preserving useful document structure rather than exact visual appearance.
HTML Files vs Webpages
MarkForge converts HTML source that you paste or upload. MarkForge does not currently fetch arbitrary webpage URLs.
If you want to convert content from a webpage, you can view its page source (or save the page as HTML) and provide that HTML source to MarkForge yourself. MarkForge does not scrape or remotely retrieve webpages on your behalf.
Safe Browser-Based HTML Conversion
MarkForge treats HTML you paste or upload as content to convert, not as a live webpage to run. The HTML is parsed into a detached, in-memory document that is never inserted into the page you're viewing, so scripts in the source are never executed.
Before conversion, MarkForge removes script, iframe, embed, object, and form elements, strips inline event-handler attributes (such as onclick), and restricts links that use unsafe schemes like javascript:. Remote images referenced in the HTML are not fetched by the converter — safe image URLs are preserved as Markdown references, and embedded data-URI images are replaced with a short text placeholder instead of a large inline string.
The output is plain-text Markdown shown in an editable panel, not rendered HTML, so nothing from your source HTML runs in your browser as part of conversion or preview.
HTML to Markdown for AI Workflows
HTML often contains presentation markup, scripts, and webpage-specific elements, while Markdown provides lightweight text structure that can be easier to inspect and prepare for text-based AI and LLM workflows.
After converting HTML to Markdown, you can clean up the output with the Markdown Cleaner, preview it with the Markdown Previewer, split long documents into sections with the Markdown Chunker, or check token counts with the AI Token Counter before using the text in an AI workflow.
Private by Design
HTML conversion happens locally in your browser. Pasted HTML, uploaded files, and generated Markdown are not sent to a MarkForge conversion server.

Frequently Asked Questions
What is HTML?
HTML (HyperText Markup Language) is the markup language used to structure content on web pages, using elements such as headings, paragraphs, links, lists, and tables.
What is Markdown?
Markdown is a lightweight plain-text formatting system. It uses simple characters to represent structure such as headings, lists, links, emphasis, tables, and code, while remaining easy to read as plain text.
How do I convert HTML to Markdown?
Paste HTML source into the text area, or upload an .html or .htm file, then click Convert to Markdown. The generated Markdown appears in an editable panel that you can review, copy, or download.
Does MarkForge upload my HTML?
No. HTML conversion happens locally in your browser. Pasted HTML, uploaded files, and generated Markdown are not sent to a MarkForge conversion server.
Can I upload an HTML file?
Yes. MarkForge accepts .html and .htm files up to 5 MB, processed entirely in your browser.
Can MarkForge convert an entire webpage by URL?
Not currently. MarkForge converts HTML source that you paste or upload — it does not fetch or scrape webpages by URL. You can provide the page's HTML source yourself if you want to convert it.
Are HTML tables converted to Markdown?
Yes. Simple HTML tables are converted into GitHub-flavored Markdown pipe tables when the Preserve Tables setting is on.
What happens to CSS and JavaScript?
CSS and JavaScript are removed before conversion. They are not represented in the generated Markdown, and no JavaScript from your HTML is ever executed.
Are images preserved?
Normal image references with safe URLs (such as https links or relative paths) are converted into standard Markdown image syntax when the Preserve Images setting is on. Images are not fetched or embedded — only the reference is preserved. Embedded data-URI images are replaced with a short "Image omitted" placeholder instead of a large base64 string.
Can I edit the Markdown before downloading it?
Yes. The generated Markdown is editable inside MarkForge. The Copy Markdown and Download .md actions use the current edited version.
Can I use the Markdown with ChatGPT, Claude, GitHub, Obsidian, or other tools?
Yes. Markdown is plain text, so you can use MarkForge output anywhere Markdown or plain text is accepted, including AI chat tools, GitHub repositories, and note-taking apps like Obsidian.
Is the HTML to Markdown converter free?
Yes. The HTML to Markdown converter is free to use and does not require an account.
