How HTML Maps to BBCode Tag Syntax

This parser formats HTML tags into BBCode elements locally inside your browser memory sandbox.

The converter uses a temporary DOM sandbox parser to read the HTML nodes. It maps tag structures sequentially: <b> to [b], <a href="..."> to [url=...], and <blockquote> to [quote]. Lists are restructured with standard [list] wrappers, and headings are converted into [size=...] text properties.

Before & After Conversion Examples

❌ Before (Structured HTML blocks)

Most forums reject raw HTML tags to prevent cross-site scripting (XSS) attacks, displaying them as plain text.

<p>This is <strong>bold</strong> content.</p>
<blockquote>A quoted citation.</blockquote>

✅ After (Converted forum-safe BBCode)

The converted BBCode is secure and formats properly inside forum engines.

This is [b]bold[/b] content.
[quote]A quoted citation.[/quote]

Common HTML to BBCode Mistakes

Publishing Unclosed Tags

Failing to close BBCode tags (e.g. using [b]Text without the closing [/b]) breaks formatting for the rest of the forum page.

Copying Script Tags

Pasting active <script> blocks into BBCode templates. Message boards reject active script layers to prevent malicious behavior.

HTML to BBCode Best Practices

Sanitize Inputs: Strip style and script tags to prevent formatting breaks.
Verify Closed Tags: Ensure all BBCode open tags have matching closing tags.
Format Lists Correctly: Structure list items using [*] inside [list] tags.
Use Size Settings for Headers: Map headings to proportioned [size] tags.

Frequently Asked Questions

What is an HTML to BBCode converter used for?

An HTML to BBCode converter translates HTML elements (like <b>, <a>, <ul>, and <blockquote>) into equivalent Bulletin Board Code tags (like [b], [url], [list], and [quote]) primarily used for forum postings.

How are headings converted into BBCode?

BBCode does not have standard heading tags like [h1] or [h2]. Instead, headings are converted using text size and weight overrides (e.g., [size=200][b]Heading Text[/b][/size]) to match size proportions.

Is it safe to copy private HTML onto this page?

Yes, this converter processes everything locally inside your browser sandbox using JavaScript. No HTML strings or parsed texts are sent to remote servers.

How are lists converted to BBCode syntax?

HTML <ul> or <ol> list hierarchies are translated using [list] containers. Individual list items (<li>) are replaced with asterisk bullet markers (e.g., [*] List Item Text).

How are hyperlinks parsed?

Anchor tags like <a href="url">Text</a> are converted into URL blocks: [url=url]Text[/url]. If the link text is identical to the target address, it collapses into [url]address[/url].

Does the converter support image tags?

Yes. Image tags like <img src="image_url" /> are parsed and replaced with standard BBCode image containers: [img]image_url[/img].

What happens to script and style tags during conversion?

The parser completely sanitizes the input, discarding code snippets inside <script> and <style> blocks to prevent security vulnerabilities and clutter.
