About This Converter
This tool runs entirely in your browser — no text is sent to any server. It uses a custom JavaScript parser that supports the most common Markdown constructs. For large or complex documents involving edge-case nesting, consider the HTML Formatter to clean up the output, or the HTML Entity Encoder if you need to display code samples safely.
When Should You Use Markdown?
Markdown is a lightweight markup language designed to be readable as plain text and easily converted to HTML. It is widely used in:
- README files on GitHub and GitLab
- Static site generators (Jekyll, 11ty, Hugo, etc.)
- Documentation systems (MkDocs, Docusaurus, Notion, etc.)
- Forum and comment systems (Reddit, Stack Overflow, etc.)
- Blog posts and CMS platforms that accept Markdown input
Frequently Asked Questions
Does the converter support all Markdown features?
It supports the most commonly used elements: headings, bold/italic/strikethrough, links, images, inline code, fenced code blocks, ordered/unordered lists, blockquotes, horizontal rules, and GFM-style tables. It does not support footnotes, definition lists, or complex nested list indentation beyond two levels.
Is my content safe?
Yes. Everything runs in your browser with no server communication. Your Markdown is never transmitted anywhere. The output HTML does not include any scripts — raw HTML tags in the Markdown source are escaped for safety.
Can I use the output HTML directly on a webpage?
Yes, the output is valid HTML fragment code that you can embed in any page. If you need it to look styled without adding your own CSS, consider wrapping the output in a container with a CSS reset or the prose class from Tailwind CSS Typography.
How is a Markdown table formatted?
Use pipes and dashes to define columns and the header separator row. For example:
| Name | Age |
|---
----|-----|
| Alice | 30 |
| Bob | 25 |
Alignment is set with colons: :--- (left), :---: (center),
---: (right).
