How to Convert Markdown to HTML

Method 1: Use an online Markdown to HTML converter

The fastest way to convert Markdown to HTML is an online converter. Paste Markdown into the editor above, and the HTML output generates instantly with a live preview, ready to copy or download. No installation is required.

An online converter suits one-off conversions and non-technical users. The converter runs in the browser, so Markdown is never uploaded to a server.

Method 2: Convert Markdown to HTML in JavaScript

In JavaScript, convert Markdown to HTML with the marked library. Call marked.parse() with a Markdown string and it returns an HTML string. The markdown-it library is an equally capable alternative.

import { marked } from 'marked';
const html = marked.parse('# Hello');

<h1>Hello</h1>

Method 3: Convert Markdown to HTML in Python

In Python, convert Markdown to HTML with the markdown package. Call markdown.markdown() with a Markdown string to return HTML. Install it first with pip install markdown.

import markdown
html = markdown.markdown('# Hello')

<h1>Hello</h1>

Method 4: Convert Markdown to HTML with Pandoc

Pandoc converts Markdown to HTML from the command line. Run pandoc input.md -o output.html to produce an HTML file. Pandoc handles large documents and supports many input and output formats.

pandoc input.md -o output.html

Method 5: Convert Markdown to HTML in a code editor

Code editors convert Markdown to HTML through extensions. In VS Code, the built-in Markdown preview renders HTML, and an extension exports it. This suits developers already editing Markdown files.

Frequently Asked Questions

What is the fastest way to convert Markdown to HTML?

An online converter is the fastest method. Paste Markdown and the HTML generates instantly with no installation. For repeated or automated conversions, a library such as marked (JavaScript) or markdown (Python) is faster.

How do I convert Markdown to HTML programmatically?

Use a parsing library: marked or markdown-it in JavaScript, markdown or markdown2 in Python, or Parsedown in PHP. Each accepts a Markdown string and returns an HTML string in a single function call.

How do I convert a Markdown file to HTML on the command line?

Use Pandoc: run pandoc input.md -o output.html. Pandoc reads the Markdown file and writes a complete HTML file, and supports GitHub Flavoured Markdown with the -f gfm flag.

Does converting Markdown to HTML preserve all formatting?

Yes. Conversion preserves headings, emphasis, lists, links, images, tables, and code blocks. GitHub Flavoured Markdown features such as task lists and strikethrough are preserved when the converter enables GFM.
