Frequently Asked Questions
What is GFM (GitHub Flavored Markdown)?
GFM is GitHub's extended Markdown format. Beyond standard Markdown, it supports tables, task lists (checkboxes), strikethrough, autolinks, and more. This tool uses the same parsing rules GitHub applies to README files.
What's the difference in line break handling?
'All newlines → <br>' converts every line break in the input to a <br> tag. 'GFM standard' only creates line breaks when lines end with 2 or more spaces or a backslash. Choose according to your use case.
What is HTML sanitization?
A security feature that removes potentially dangerous HTML tags and attributes. It prevents XSS (Cross-Site Scripting) attacks. Keep it enabled by default; only disable for trusted content.
Is code block syntax highlighting supported?
Code blocks are converted to <pre><code> tags with language classes. Syntax highlighting requires additional CSS or JavaScript library integration.
Is my input data sent to a server?
No. Markdown parsing and HTML generation are handled locally by the marked library running in your browser. Your content is never transmitted externally.
