工具介绍

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

工具概览

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.

使用场景

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.

常见问题

Is the output safe to drop into a page?+

Yes. Raw HTML in the input is escaped, and only a known allow-list of tags is converted to real HTML.

Which tags are supported?+

b, i, u, s, url, img, color, size, quote, code, list, *, h1–h6, center, and br. Unknown tags are left as plain text.

Does it handle nested tags?+

Yes. Inline tags can be nested inside one another and inside block tags like [quote] and [list].
