Markdown Editor

About the Markdown Editor

Our Markdown editor is a free online tool that provides a live side-by-side editing and preview experience for writing Markdown documents. Markdown is a lightweight markup language widely used for documentation, README files, blog posts, technical writing, and note-taking. This editor lets you write Markdown on the left and instantly see the rendered HTML output on the right.

The editor includes a full-featured toolbar for quickly inserting common Markdown syntax such as headings, bold, italic, links, images, code blocks, lists, blockquotes, and horizontal rules. You do not need to memorize Markdown syntax to get started. Simply click the toolbar buttons to insert formatting at your cursor position, or type Markdown directly if you prefer.

Your document is never uploaded. Images you link from other websites are loaded from those sites for the preview. The editor supports real-time preview, character and word counting, clipboard copying for both Markdown and HTML output, and direct file download as a .md file.

How to Use the Markdown Editor

1. Start writing: The editor loads with sample content showing all supported Markdown features. Clear it to start fresh, or modify the sample to see how each syntax element works.
2. Use the toolbar: Click any toolbar button to insert the corresponding Markdown syntax at your cursor position. Select text first to wrap it with formatting like bold or italic.
3. Preview instantly: As you type, this basic parser updates a filtered preview. Target Markdown renderers can differ, so check formatting on the destination before publishing.
4. Check your stats: The character and word counts update live above the editor, helping you track document length for requirements or word limits.
5. Copy or download: Use the "MD" button to copy your raw Markdown, the "HTML" button to copy the rendered HTML, or the "Save" button to download your document as a .md file.

Supported Markdown Syntax

• Headings: Use # for H1, ## for H2, ### for H3, and #### for H4. Each heading level creates progressively smaller text with appropriate spacing.
• Bold and Italic: Wrap text in **double asterisks** or __double underscores__ for bold, and *single asterisks* or _single underscores_ for italic.
• Links: Create clickable links with [link text](URL) syntax. Links open in a new tab for convenience.
• Images: Embed images with  syntax. Images are displayed responsively with rounded corners.
• Code: Use backticks for inline code and triple backticks for multi-line code blocks. Code has a styled background; language-specific syntax highlighting is not provided.
• Lists: Start lines with - or * for unordered bullet lists, and 1. for ordered numbered lists.
• Blockquotes: Start a line with > to create a styled blockquote with a blue left border accent.
• Horizontal Rules: Use ---, ***, or ___ on a line by itself to create a visual separator between sections.
• Line Breaks: Use double newlines to create paragraph breaks, or single newlines within paragraphs for line breaks.

Use Cases

• README Files: Draft README.md files with this basic preview, then confirm rendering on GitHub. This parser does not implement the complete GFM specification.
• Technical Documentation: Create documentation for APIs, libraries, and software projects with proper formatting, code blocks, and structured headings.
• Blog Posts: Draft blog content in Markdown format, preview the layout, then copy the HTML to paste into your content management system.
• Note-Taking: Use Markdown for structured notes during meetings, lectures, or research. Download notes as .md files for organized storage.
• Email Formatting: Write content in Markdown and copy filtered HTML source text. Use an HTML-aware editor or import workflow; a rich-text editor may paste source as plain text.
• Learning Markdown: Use the toolbar buttons and quick reference to learn Markdown syntax interactively with instant visual feedback.
• Content Migration: Convert Markdown content to HTML for embedding in websites, wikis, and knowledge base systems.

Frequently Asked Questions

Tips & Best Practices

• Use headings for structure: Organize your documents with a clear heading hierarchy. Start with H1 for the title, H2 for major sections, and H3 for subsections.
• Preview as you write: Keep the preview panel visible to catch formatting issues early and ensure your document looks exactly how you intend.
• Select text before formatting: Highlight text in the editor before clicking a toolbar button to wrap the selected text with the chosen formatting.
• Use code blocks for technical content: Wrap code snippets, commands, and configuration examples in code blocks to preserve formatting and improve readability.
• Save frequently: Use the download button to save your work as a .md file. Markdown files are plain text and can be opened in any text editor.
• Learn Markdown syntax: Use the toolbar or type Markdown syntax directly, such as ** for bold and * for italic. This source editor does not define dedicated formatting keyboard shortcuts.
