What Markdown features are supported?

We support all standard Markdown syntax: headers (# ## ###), bold/italic (**bold** *italic*), lists (ordered and unordered), links ([text](url)), images (![alt](url)), code blocks (```language```), inline code (`code`), blockquotes (>), and horizontal rules (---). GitHub Flavored Markdown extensions like tables and strikethrough are also supported.

Can I export the HTML with custom styling?

The exported HTML includes basic styling. For custom CSS, edit the HTML file after export or use desktop Markdown editors that support custom themes. The HTML structure is clean and semantic, making it easy to add your own styles.

Does it support math equations or diagrams?

No, we support standard Markdown only. For math equations (LaTeX) or Mermaid diagrams, use specialized Markdown editors like Typora, Mark Text, or VS Code with extensions. These features require additional rendering libraries.

Can I save my Markdown files?

The tool doesn't have built-in file saving. You can copy your Markdown text and save it manually, or export the HTML and save that. For persistent file management, use desktop Markdown editors or version control systems like Git.

What's the maximum file size I can edit?

The practical limit is about 1MB of text (roughly 20,000 lines), limited by browser memory. For best performance, keep files under 500KB. Very large files may cause browser slowdowns. For larger files, use desktop editors like VS Code.

When to Use This Tool

Use this when:

You're writing README files for GitHub projects and want to preview formatting
You're creating blog posts in Markdown and need to see how they'll render
You're writing documentation and want to verify Markdown syntax is correct
You need to convert Markdown to HTML for websites or emails
You're learning Markdown and want to see how syntax translates to formatted output
You're preparing content for platforms that support Markdown (GitHub, Reddit, etc.)
You want to preview Markdown before committing to version control

Don't use this if:

You need advanced Markdown features like math equations or Mermaid diagrams (use specialized Markdown editors)
You require collaborative editing or version control integration (use VS Code with Markdown extensions)
You need to edit very large Markdown files (10,000+ lines) that may cause browser slowdowns
You require custom CSS styling or advanced HTML export options (use desktop Markdown editors)
You need to work with multiple Markdown files simultaneously (use desktop editors)

What is a Markdown Preview Tool?

A Markdown preview tool lets you write Markdown syntax and see the rendered HTML output in real time. Our editor processes everything in your browser — your documents are never sent to any server.

Markdown is the standard lightweight markup language used for README files on GitHub, documentation sites, blog posts, technical writing, and note-taking. Being able to preview rendered output while writing ensures your formatting, links, images, code blocks, and tables appear exactly as intended before publishing.

This tool is essential for developers writing README files and documentation, technical writers creating guides and tutorials, bloggers drafting posts in Markdown format, students writing formatted notes, and anyone who uses Markdown regularly and wants a quick preview without setting up a local environment.

Compared to IDE extensions (which require specific editor setup), dedicated Markdown editors like Typora (which are paid), or online editors that may store your content, PureXio's preview tool is free, private, and accessible from any browser. It supports GitHub Flavored Markdown (GFM) including tables, task lists, strikethrough, and syntax-highlighted code blocks.

The editor features a split-pane view with synchronized scrolling — write on the left, see the rendered output on the right in real time. It includes a toolbar for common formatting shortcuts and supports exporting the rendered content.

Best for: writing and previewing Markdown in real time. Supports GitHub Flavored Markdown, code highlighting, tables. Split-pane editor. Fully private.

How to Use Markdown Preview

Type or paste your Markdown content in the left editor panel

See live preview of formatted output in the right panel as you type

Export to HTML or copy the formatted content for use in your projects

Common Use Cases

Write and preview README.md files for GitHub repos (50-200 lines) with proper formatting

Create blog posts in Markdown and export to HTML for websites (1000-3000 words)

Write technical documentation and preview how it will render (10-50 pages)

Convert Markdown notes to HTML for email or website publishing (500-1500 words)

Learn Markdown syntax by typing and seeing real-time preview (practice with 20-50 lines)

Preview Markdown content before posting to Reddit, GitHub, or forums (check formatting for 100-500 word posts)

Format Markdown files for documentation sites like GitBook or Docusaurus (convert 5-20 page docs)

Limitations & Constraints

Maximum file size: ~1MB text (browser memory limit). For larger files, use desktop editors.

No math equation support (LaTeX). Use specialized Markdown editors for mathematical content.

No Mermaid diagram support. Use desktop editors with diagram extensions.

No file saving or version control. Copy content manually or use desktop editors.

No collaborative editing. For team collaboration, use VS Code with Live Share or online Markdown editors.

Troubleshooting

Markdown syntax isn't rendering correctly

Solution: Check for common syntax errors: missing spaces after # for headers, proper list indentation, closed code blocks (```), and proper link/image syntax. Some Markdown flavors have different rules—ensure you're using standard Markdown syntax. Prevention: Learn standard Markdown syntax. Use a Markdown cheat sheet for reference.

Preview panel is blank or not updating

Solution: Refresh the page and try again. Check browser console for JavaScript errors. Ensure your Markdown syntax is valid. Very large files may cause rendering delays—wait a few seconds. Try with a smaller Markdown sample to verify the tool works. Prevention: Keep files under 500KB for reliable rendering.

Exported HTML doesn't look right in my website

Solution: The exported HTML includes basic styling. You may need to add custom CSS to match your website's design. The HTML structure is semantic and clean—add your own stylesheet. Some Markdown features may render differently in different contexts. Prevention: Test exported HTML in your target environment. Add custom CSS as needed.

Code blocks aren't syntax highlighted

Solution: Syntax highlighting requires specifying the language after the opening ``` (e.g., ```javascript, ```python). Without a language specified, code blocks render as plain text. Use language identifiers for proper highlighting. Prevention: Always specify the programming language in code blocks for better readability.

Tables or other GitHub Flavored Markdown features don't work

Solution: We support GitHub Flavored Markdown including tables. Ensure table syntax is correct: pipes (|) for columns, dashes (---) for header separator, proper alignment. Some advanced GFM features may not be supported. Check the Markdown syntax guide. Prevention: Use standard Markdown syntax when possible. Test GFM features before relying on them.
