Frequently Asked Questions
What Markdown syntax is supported?
Headers (H1-H6), bold, italic, links, images, ordered and unordered lists, fenced code blocks, inline code, blockquotes, horizontal rules and paragraphs.
Is my text stored or uploaded anywhere?
No. All rendering happens locally in your browser. Your text never leaves your device.
Can I copy the generated HTML?
Yes. Click the "Copy HTML" button in the toolbar to copy the rendered HTML markup to your clipboard.
How do I switch between side-by-side and stacked layout?
Use the "Side by Side" and "Stacked" buttons in the toolbar above the editor. Stacked layout places the preview below the editor, which can be useful on smaller screens.
Does this support GitHub-flavored Markdown?
This tool supports core Markdown syntax including fenced code blocks. Advanced GFM features like tables or task lists are not included.
