Markdown Editor & README Generator
Compose Markdown documents, generate professional GitHub profile READMEs, and download outputs instantly.
What is the Markdown Editor & README Generator?
Markdown is the standard plain-text formatting language for developer documentation, GitHub README files, blogs, and technical writing. This free online Markdown editor gives you a split-pane workspace — type Markdown on the left, see it rendered in real time on the right. Choose from 8 pre-built README templates (project docs, developer profiles, API references, CLI tools, and more) to scaffold professional documentation in seconds. Insert formatted tables with the table generator, apply toolbar shortcuts for bold, italic, headings, and code blocks, then export your finished document as clean HTML or a downloadable .md file. Everything runs client-side — your content never leaves your browser.
How to use the Markdown Editor & README Generator?
- Select a template from the 'README Templates' dropdown to kickstart your project profile, or type your own Markdown.
- Use the toolbar to quickly insert bolding, italics, code snippets, lists, or custom table structures.
- Type on the left and see the fully parsed preview render on the right in real-time.
- Click 'Export HTML' to download the raw HTML source code, or click 'Export MD' to download the standard Markdown file.
Frequently Asked Questions
Is this Markdown editor safe and private?
Yes. This editor runs entirely in your browser using JavaScript. Your content is never sent to any server — it stays on your device. Files are generated and downloaded locally, making it safe for private documentation, internal READMEs, and sensitive project notes.
What is Markdown?
Markdown is a lightweight markup language that uses plain-text formatting syntax (like # for headings, ** for bold, - for lists) to create structured documents. It is widely used for README files on GitHub, documentation sites, blogs, and technical writing because it is simple to read and write.
How do the README templates work?
Select a template from the dropdown (e.g., 'Developer Profile', 'API Documentation', 'Open Source Project'). The editor loads a pre-structured Markdown document with placeholder content, badges, and sections. Edit the text to match your project, then export as .md and commit it to your repository.
Can I export to PDF?
Yes. Click the 'Print / PDF' button. It opens your browser's print dialog with a clean stylesheet that hides the editor UI, giving you a document-ready print. Choose 'Save as PDF' in the print dialog to download a PDF file.
What Markdown syntax is supported?
The editor supports headings (H1–H6), bold, italic, inline code, fenced code blocks with syntax highlighting, blockquotes, ordered and unordered lists, tables, horizontal rules, images, and hyperlinks. It covers the most common Markdown features used in GitHub-flavoured documents.
How does the table generator work?
Click the table icon in the toolbar, specify the number of columns and rows, then click 'Insert'. The editor generates a properly formatted Markdown table with header row, separator row, and data rows — ready for you to fill in.
