Markdown to HTML Converter
Transform Markdown into HTML with live preview
What This Tool Does
This Markdown to HTML converter transforms Markdown-formatted text into clean HTML code. It processes common Markdown syntax including headers, lists, links, bold and italic text, code blocks, and blockquotes.
The conversion runs in your browser. When you paste Markdown or upload a file, it processes the content locally without sending anything to a server. You can view both the HTML source code and a styled preview of how the content will appear.
Who Needs This
Content writers who draft articles in Markdown need to convert their work to HTML for publishing on websites or content management systems. This tool generates clean HTML without extra markup.
Web developers building static sites or documentation often write content in Markdown for simplicity, then convert it to HTML for deployment. The tool handles the conversion quickly during the development process.
Technical writers creating README files, documentation, or blog posts in Markdown can use this to preview how their content will look when rendered and export HTML for various platforms.

Supported Markdown Syntax
The converter handles standard Markdown formatting:
Headers: Use # for h1, ## for h2, up to ###### for h6. Headers must have a space after the hash symbols.
Emphasis: Wrap text in single asterisks or underscores for *italic* and double asterisks or underscores for **bold**. Combine them for ***bold italic***.
Lists: Start lines with asterisks, hyphens, or plus signs for unordered lists. Use numbers followed by periods for ordered lists. Indent with spaces for nested lists.
Links: Format links as [text](url). The text appears as the clickable link, and url is the destination.
Code: Wrap inline code in single backticks. Create code blocks by wrapping text in triple backticks on separate lines.
Blockquotes: Start lines with > to create blockquotes. Great for quotes or callout sections.
Horizontal Rules: Create dividing lines with three or more hyphens, asterisks, or underscores on a line.
Limitations
This converter implements basic Markdown syntax. It doesn't support extended Markdown features like tables, task lists, footnotes, or GitHub-flavored Markdown extensions.
The tool uses regex-based parsing, which works well for standard Markdown but may not handle complex nested structures or edge cases as robustly as full Markdown parsers like CommonMark implementations.
HTML tags in your Markdown will be escaped for safety. If you need to include raw HTML, you'll need to unescape it manually after conversion.
Privacy and Security
This converter operates entirely within your browser using JavaScript. When you upload a Markdown file or paste content, nothing is transmitted to any server. The file is read and processed locally on your device.
This matters when working with unpublished articles, confidential documentation, or proprietary content. Since conversion is client-side, there's no risk of exposing your content through network transmission.
The tool doesn't store your Markdown or HTML in browser cache or local storage. When you close the tab, all content is cleared from memory.
Common Questions
Markdown is a lightweight text format that's easier to read and write than HTML. It uses simple syntax like # for headers and ** for bold. HTML is the standard markup language for web pages. Markdown gets converted to HTML for display in browsers.
This tool supports basic Markdown syntax including headers, lists, links, emphasis, code blocks, and blockquotes. It doesn't support extended features like tables, footnotes, or task lists which are part of GitHub-flavored Markdown.
No. All conversion happens in your browser. The file is read locally on your device and never sent anywhere.
This tool only converts Markdown to HTML. Converting HTML back to Markdown is a different process that requires a separate tool because HTML can represent structures that don't have Markdown equivalents.
The converter generates semantic HTML structure without inline styles or CSS classes. You need to add your own CSS styling to the HTML, either with external stylesheets or by wrapping the output in styled HTML.
You can upload .md, .markdown, and .txt files. The tool reads them as plain text, so any file containing Markdown-formatted text will work regardless of the extension.
