Markdown to HTML: Copy a Fragment or Download a Page

Markdown needs to be rendered before a browser can display it as a structured document. The Markdown to HTML converter produces HTML from source text in your browser. You can copy the content markup or download a complete page.

Those outputs serve different purposes: a content fragment fits inside an existing CMS or web page, while a complete document has its own page structure and styles. Choose the output that your destination accepts, then check the published result.

Convert a document

1. Open the Markdown to HTML tool.
2. Paste your source or select a .md, .markdown, or .txt file.
3. Switch between the preview and HTML code to compare the content with its markup.
4. Use Copy HTML for the content fragment, or download the HTML file for a complete page.
5. Open the saved file or paste the fragment into a draft at the destination and inspect it.

The converter reads and parses the source locally. It does not submit your Markdown to a server conversion endpoint. Remote images and external page dependencies can still make network requests.

A small before-and-after example

## Review status

Keep the **source file**.

- Read the draft
- Check the links

[Project](https://example.com/project)

The content markup includes this structure:

<h2>Review status</h2>
<p>Keep the <strong>source file</strong>.</p>
<ul>
<li>Read the draft</li>
<li>Check the links</li>
</ul>
<p><a href="https://example.com/project">Project</a></p>

Whitespace and generated heading IDs can vary. The useful check is that the document contains actual headings, paragraphs, lists, and links rather than a picture of them.

Fragment versus complete page

Output	Contains	Best use
Copied HTML	The converted content markup	A CMS field or an existing page body
Downloaded HTML	A document wrapper, content, and default styles	Opening as a separate page or adapting for publishing
Original Markdown	The editable source	Ongoing writing and version control

A fragment relies on the destination's styles. The downloaded page supplies a default layout, but its external resources still need to be available. For example, the current page includes a KaTeX stylesheet link for math. A downloaded file is therefore not guaranteed to be fully self-contained or to reproduce every feature offline.

HTML for email has additional layout and CSS restrictions. A web page export is not automatically an email template; test any content you adapt in the email clients your audience uses.

What this converter supports

Common headings, emphasis, paragraphs, links, lists, and GFM pipe tables become corresponding HTML elements. Math is rendered through KaTeX. In this tool, Mermaid remains a code block; it does not include the diagram-rendering step used by the Markdown viewer.

Raw HTML from user input is removed. That means tags such as <ins>, <u>, and <br> may not survive as formatting. The underline guide explains the compatibility issue. Use Markdown's own emphasis and line-break syntax where possible.

Exporting also does not copy your local image folder. A relative URL is kept relative to the resulting page's location. If ./images/chart.png is missing there, the image cannot load. Keep the exported page and its assets in the expected structure or update the links before publishing.

Check the destination

Heading hierarchy. Place the converted content at a level that fits the surrounding page. If the CMS already supplies a page title, starting the fragment with ## can be more appropriate than adding another top-level title.

Styles. A CMS can restyle tables, code, and quotations. A correct markup fragment does not guarantee an identical visual result after it is embedded.

Allowed content. Platforms can remove elements, attributes, or external styles. Equations may need additional configuration at the destination. Inspect the final page rather than relying on the converter preview alone.

Links and images. Click each important link and load the page from its final URL. Relative links that work on one path can break on another. Remote images contact their hosts and may be restricted by permissions or network policy.

Literal syntax. Put examples of Markdown or HTML inside code spans or code blocks. This prevents tutorial examples from being interpreted as document structure.

Keep the original

HTML is useful for publishing, while Markdown is often easier to revise. Save both when the output will need maintenance. If you start from an HTML page instead, use HTML to Markdown, then review the converted text: custom layout and styles do not have a direct Markdown equivalent.

For the website's separate network and data practices, read the privacy policy. Browser-side conversion describes where the source is processed; it does not imply that the page and all embedded resources operate without a connection.
