Convert Markdown to HTML — GFM-compatible rendering in your browser
Drop a .md or .markdown file below and get a clean HTML5 document back. Uses marked with GitHub-flavored Markdown support. Everything runs locally.
Your file is processed entirely in your browser. Nothing is uploaded.
Markdown is the writing format of developers, technical writers, and static-site authors. It is plain text with lightweight syntax for headings, bold, italic, lists, links, code blocks, and tables — readable in a text editor, parseable by a renderer, and diff-friendly in version control. But when you need to publish Markdown content to the web, view it styled, or share it with non-technical readers, you need it as HTML. The convention for Markdown rendering is GitHub-flavored Markdown (GFM), which adds useful extensions to the original spec: tables, fenced code blocks, strikethrough, task lists, and autolinks.
This converter uses marked, the canonical JavaScript Markdown parser, configured in GFM mode. It reads your .md file, parses it into a structured document tree, and emits clean semantic HTML. The output is wrapped in a complete HTML5 document with a minimal built-in stylesheet so it opens and looks good in any browser immediately. Nothing is uploaded, and marked is dynamically loaded so pages that do not use it stay lean.
How to convert Markdown to HTML in 4 steps
- 1
Select your Markdown file
Drop the .md or .markdown file into the dropzone or click to browse.
- 2
Let marked parse the content
The marked library tokenizes your Markdown, builds a document tree, and emits clean semantic HTML tags.
- 3
Get a full HTML5 document
The parsed HTML is wrapped in a <!doctype html> document with charset, viewport, and a small built-in stylesheet so it renders cleanly in any browser.
- 4
Download the HTML file
Save the .html to your device. Open in a browser to preview, publish it on a static site, or paste the body into any CMS.
Markdown vs HTML: writing versus rendering
Markdown is a writing format — it is the syntax you use when you want to produce structured content without the overhead of HTML tags. HTML is a rendering format — it is what browsers actually display. Converting Markdown to HTML is the build step that turns author-friendly syntax into browser-ready markup. Most static site generators, documentation tools, and README viewers do this internally. When you need to do it once, for a specific file, without setting up a whole build pipeline, a direct converter like this one is the fastest path. The output is standard HTML: you can publish it, style it further, embed it in a page, or just open it in a browser to read.
When should you convert Markdown to HTML?
Previewing a README before publishing
Sometimes you want to see how a README will render on GitHub or GitLab without pushing first. Converting locally gives you an instant preview.
Publishing a single article without a static-site generator
If you have one Markdown file you want on the web and no time to set up Hugo or Eleventy, converting to HTML and uploading the file works immediately.
Turning meeting notes into a shareable web page
Notes written in Markdown during a meeting can be converted and shared as a polished HTML document in seconds.
Feeding content into a CMS that accepts HTML
Many CMS editors accept pasted HTML but not Markdown. Converting gives you content you can drop directly into the editor.
Frequently asked questions
- Which Markdown dialect does it support?
- GitHub-flavored Markdown (GFM), which includes the original spec plus tables, fenced code blocks, strikethrough, task lists, autolinks, and a few other extensions. This is the same dialect you see rendered on GitHub and GitLab.
- Does it handle code blocks?
- Yes. Fenced code blocks (triple backticks) and indented code blocks are both parsed and rendered with <pre><code> tags. Syntax highlighting itself is not applied — for highlighted code, run the output through Prism or Highlight.js separately.
- Are tables supported?
- Yes, GFM-style tables with the pipe syntax are rendered as HTML <table> elements with proper <thead> and <tbody>. Basic alignment (left, right, center) declared via colons is preserved.
- Is the HTML styled?
- The output is wrapped in a full HTML document with a minimal built-in stylesheet: pleasant fonts, sensible margins, a light code background, and readable tables. If you want unstyled HTML, remove the <style> block from the output.
- Is my Markdown uploaded?
- No. The marked library loads dynamically into your browser and runs the parse locally. Your .md file is read locally and the HTML is produced locally. Nothing is ever uploaded or logged.
