Dealing with old forum code? Learn what BBCode is, how tags like `[b]` and `[url]` work, and how to instantly convert any BBCode to clean HTML with a free online converter.

Before the age of social media giants, the internet was built on communities—thriving forums and message boards where users discussed everything from technology to hobbies. Even today in 2025, the legacy of these platforms lives on in countless databases and archives.

If you've ever managed one of these communities or tried to migrate its content, you've likely encountered a special type of markup: BBCode.

But what is this format, and how do you convert it to the modern HTML used by today's websites? This guide will break it down for you.

What is BBCode?

BBCode, which stands for Bulletin Board Code, is a lightweight markup language created for use in online forums. Its primary purpose was to allow users to format their posts (make text bold, add images, create links) without giving them the ability to write actual HTML.

This was a crucial security measure. Allowing users to write raw HTML would have opened the door to malicious scripts (<script>) and page-breaking code. BBCode provided a safe, limited, and simple set of tags that the forum software could easily translate into secure HTML. Instead of HTML's angle brackets (<>), BBCode uses square brackets ([]).

Common BBCode Tags and Their HTML Equivalents

While there were many variations, most BBCode implementations used a standard set of tags. Here’s how the most common ones translate to HTML:

BBCode Syntax	HTML Equivalent	Purpose
`[b]Bold Text[/b]`	`<strong>Bold Text</strong>`	To make text bold.
`[i]Italic Text[/i]`	`<em>Italic Text</em>`	To make text italic.
`[u]Underlined[/u]`	`<span style="text-decoration:underline;">Underlined</span>`	To underline text.
`[url=https://example.com]Click Here[/url]`	`<a href="https://example.com">Click Here</a>`	To create a link with custom text.
`[img]https://image.com/pic.jpg[/img]`	`<img src="https://image.com/pic.jpg" alt="">`	To embed an image.
`[quote]Someone's quote[/quote]`	`<blockquote>Someone's quote</blockquote>`	To create a quote block.
`[code]myFunction();[/code]`	`<pre><code>myFunction();</code></pre>`	To display formatted code.
