Tips for Writing Better Markdown

Use blank lines between blocks — Separate headings, paragraphs, lists, and code blocks with blank lines. This prevents accidental formatting merges and makes your Markdown source more readable.
Preview heading hierarchy — Use a single H1 per document for the title, then H2 for sections, H3 for subsections. This creates a logical document structure that is easier to navigate and better for SEO.
Escape special characters — If you need to display raw Markdown characters like asterisks or backticks, escape them with a backslash to prevent them from being interpreted as formatting syntax.
Use reference-style links for readability — Instead of inline URLs, define references at the bottom of your document. This keeps the main text clean and makes links easier to manage and update.

Frequently Asked Questions

What Markdown syntax is supported?

We support CommonMark and GitHub Flavored Markdown, including headings, bold, italic, links, images, lists (ordered and unordered), tables, code blocks with syntax highlighting, blockquotes, horizontal rules, and more. Check the preview pane to see how your syntax renders.

Is my Markdown data sent to a server?

No. All Markdown parsing and HTML rendering happens locally in your browser using JavaScript. Your content never leaves your device, ensuring complete privacy and security for your documents.

Can I export the rendered HTML?

Yes! Click the "Copy HTML" button to copy the rendered HTML code to your clipboard. You can then paste it into any HTML editor, content management system, or website. The HTML includes inline styles for basic formatting.

Does this support syntax highlighting for code blocks?

Basic code blocks are supported with monospace font and background styling. While this tool doesn't include full syntax highlighting libraries, you can wrap your code in triple backticks with a language identifier (e.g., ```javascript) and it will display properly in a code block.

Can I use this for previewing README files?

Absolutely! This tool is perfect for previewing GitHub README files, documentation, blog posts, and any Markdown content. Copy your README content here, see how it looks, then copy the HTML for use elsewhere or paste the Markdown back.

Is this tool free to use?

Yes, the Markdown preview tool is completely free to use with no registration required. There's no limit on the amount of text you can preview or how many times you can use it. Works on any modern browser.

What is the difference between Markdown and HTML?

Markdown is a lightweight markup language designed to be easy to read and write in its raw form. It uses simple syntax like asterisks for bold and hashes for headings. HTML is a more comprehensive markup language with extensive tags and attributes for complex page layouts. Markdown compiles down to HTML, making it a great authoring format. Most content management systems and documentation platforms support Markdown because it strikes a good balance between simplicity and expressiveness for content creation.

Can I add custom CSS to my Markdown output?

This preview tool applies basic styling for readability, but the rendered HTML output can be styled with your own CSS when used on your website. The tool generates semantic HTML with standard tags like h1, h2, p, ul, ol, pre, code, blockquote, and table. You can target these elements with custom CSS rules on your site to match your design system. When copying the HTML output, you can wrap it in a container div and apply your own stylesheets to customize the appearance.

Do I need to create an account to use this tool?

No. All our tools are free to use and work directly in your browser without registration or sign-in. Just open the page and start using the tool.

Does this tool work on mobile devices?

Yes. The tool is fully responsive and works on any modern browser on iPhone, iPad, Android phones and tablets. The interface adapts to your screen size automatically.
