HTML/UBB Converter

A bidirectional converter between HTML markup and UBBCode (BBCode) forum tags. It maps the common forum tags [b], [i], [u], [s], [url], [img], [quote], [code], [list], [size], [color], and [list=1] to and from their HTML equivalents, and decodes basic HTML entities (&, <, >, ", ',  ) when going HTML to UBB.

1. Pick a direction with the two tabs: HTML to UBB or UBB to HTML. 2. Paste your source markup into the input card (HTML when converting to UBB, UBB code when converting to HTML). 3. Click Convert to produce the result. 4. Use Swap to flip the direction and load the result back into the input, or Copy to copy the output. Clear wipes both fields.

HTML tags map as follows: <b>/<strong> -> [b], <i>/<em> -> [i], <u> -> [u], <s>/<strike>/<del> -> [s], <a href> -> [url=...], <img src> -> [img], <h1>/<h2>/<h3> -> [size=7/6/5], <font color> -> [color=...], <font size> -> [size=...], <blockquote> -> [quote], <pre>/<code> -> [code], <ul> -> [list], <ol> -> [list=1]. When converting UBB to HTML, newlines become <br /> tags. Unknown HTML tags are stripped in the HTML-to-UBB direction.
