Frequently Asked Questions

What is Markdown?

Markdown is a lightweight markup language with plain text formatting syntax. It is designed so that it can be converted to HTML and many other formats using a tool, making content writing for the web clean and fast.

Does this previewer support GitHub Flavored Markdown (GFM)?

Yes. The previewer supports GFM features, including tables, strikethrough text, autolinks, task list checkboxes, and fenced code blocks with code language identifiers.

Can I export the rendered HTML?

Yes. You can click the "Copy HTML" action to copy the fully compiled raw HTML markup of your previewed Markdown directly to your clipboard.

Is my document private?

Yes. All parsing and HTML rendering happens 100% client-side inside your browser. No text you write or load is ever sent to a server.

Why isn't my Markdown table rendering correctly?

Markdown tables require a specific format. You must have at least one pipe | per row, and the second row must contain a separator line of dashes --- to separate the header from the data cells. Ensure there is no blank line between the header and the data.

How do I add an image in Markdown?

To insert an image, use the syntax ![Alt text](image_url). It is very similar to a standard hyperlink, but it starts with an exclamation mark.

Can I use regular HTML inside Markdown?

Yes! Standard HTML tags like <div>, <span>, or <iframe> are fully supported in most Markdown processors. If you need complex formatting that Markdown doesn't support natively, you can safely write HTML directly in the editor.

How do I create a line break or new paragraph?

To create a new paragraph, simply leave a blank line between blocks of text. To create a soft line break (a <br> tag without starting a new paragraph), add two spaces at the very end of the line before pressing Enter.

What is the difference between standard Markdown and GitHub Flavored Markdown (GFM)?

Standard Markdown (created by John Gruber) is very basic. GFM adds extra, widely-used features specifically for developers, such as tables, task lists (checkboxes), strikethrough text, and fenced code blocks with syntax highlighting.

Why isn't my code block formatting with syntax highlighting?

To get syntax highlighting, you must use a fenced code block (three backticks ) and specify the language identifier immediately after the first set of backticks, for example: javascript.
