BBCode (Bulletin Board Code) is a lightweight markup language used on forums and message boards to format posts. Tags are written in square brackets, such as [b]bold[/b] or [url]links[/url], and are converted to safe HTML when displayed.

Which BBCode tags does this viewer support?

The viewer renders common tags including [b] for bold, [i] for italic, [u] for underline, [url] for links, [img] for images, [quote] for quoted text, and [code] for code blocks, plus several more.

Does the editor show a live preview?

Yes. As you type or paste BBCode into the editor, the preview panel updates instantly so you can see exactly how the formatted text will look before posting.

Does this tool convert BBCode to HTML?

Yes. The viewer parses your BBCode and renders it as HTML in the preview, letting you confirm the final formatting that forum software will produce.

Is my BBCode sent to a server?

No. All parsing and rendering happen entirely in your browser, so your text never leaves your device and nothing is uploaded.
