Tool Introduction

Convert classic forum BBCode like [b], [url], [img], [quote], and [code] into clean, safe HTML. Handles nested tags and lists.

Tool Overview

BBCode is the markup language used by phpBB, vBulletin, and similar forum software. This tool maps the most common BBCode tags to their HTML equivalents — bold, italic, underline, links, images, lists, code blocks, and quotes — while escaping any raw HTML in the input so the output is safe to render. Color and size tags are converted to inline styles. Unsupported or malformed tags are left as plain text instead of producing broken HTML.

Use Cases

  • Migrate forum posts from phpBB or vBulletin to a modern HTML CMS.
  • Render BBCode pasted into a chat or feedback widget.
  • Pre-process legacy BBCode archives for indexing.

Input/Output Examples

Input Intent
[b]Hello[/b], visit [url=https://example.com]Example[/url]!
Output Intent
<strong>Hello</strong>, visit <a href="https://example.com">Example</a>!
