Markdown online means you can work with Markdown without installing a desktop app. Write the source, check the rendered output, and save the result in the format your next step needs.

A Markdown viewer renders plain Markdown into a readable document. It helps you check structure, links, tables, and code blocks before editing, exporting, or sharing.

Markdown preview is the rendered view of your Markdown source. It is useful for catching broken tables, uneven heading levels, missing links, and code fence mistakes before export.

A Markdown table needs a header row, a separator row, and one or more data rows. Pipes separate columns; hyphens in the second row tell the renderer where the header ends.

A Markdown link looks like `[label](https://example.com)`. The label is what readers see; the URL is where the link goes.

Markdown uses plain text characters for formatting: `#` for headings, `**` for bold, `*` for italic, brackets for links, backticks for code, and pipes for tables.

`**text**` renders as bold text. The opening `**` starts the bold section, and the closing `**` ends it.

`** **` is not a useful finished pattern because it contains only a space. Replace the space with real text: `**important note**`.

Use `→` directly in Markdown when your editor supports Unicode. If your publishing system prefers HTML entities, use `→`.
