Frequently Asked Questions
What Markdown syntax is supported?
The previewer supports GitHub Flavored Markdown (GFM): headings (#–######), bold (**text**), italic (*text*), strikethrough (~~text~~), inline code (`code`), fenced code blocks (```), links ([text](url)), images, ordered and unordered lists, blockquotes, horizontal rules (---), and tables.
What is GitHub Flavored Markdown?
GitHub Flavored Markdown (GFM) is a widely used Markdown dialect that adds tables, task lists, strikethrough, and fenced code blocks to the original Markdown spec. It is the format used by GitHub READMEs, GitLab, Notion, and many other platforms.
Can I copy the generated HTML?
Yes — click the "Copy HTML" button above the preview panel to copy the raw HTML output to your clipboard. This is useful when you need the rendered HTML for use in a CMS or email template.
Does the preview update in real time?
Yes. The preview re-renders as you type with no need to click a button. Rendering is synchronous and instant for typical document sizes.
Is my content stored anywhere?
No. All rendering happens locally in your browser. Text up to 2,000 characters is saved to the URL hash so you can share a link to your Markdown, but nothing is sent to any server.
