Frequently Asked Questions
What is Markdown?
Markdown is a lightweight markup language that converts plain text to HTML. It uses simple symbols like # for headings, ** for bold, and - for lists. It is widely used for README files, documentation, and blog posts.
What Markdown features are supported?
This editor supports: headings (# to ######), bold (**text**), italic (*text*), strikethrough (~~text~~), inline code (`code`), code blocks (```), unordered lists (- or *), ordered lists (1.), links ([text](url)), images (), blockquotes (>), horizontal rules (---), and tables.
Can I export my Markdown as HTML?
Yes. Click "Copy HTML" to copy the rendered HTML to your clipboard, or "Copy Markdown" to copy the raw Markdown source.
Is my content saved?
No. Content exists only in your browser during your session. Refresh the page and it is gone. For persistent editing, copy your Markdown to a text file.
Can I use this for GitHub README files?
Yes. This editor supports GitHub Flavored Markdown (GFM) including tables and strikethrough. The preview closely matches how GitHub renders README files.
