Summary — What Free Markdown to BBCode Converter Does

What This Free Tool Is

Free Markdown to BBCode Converter translates GFM-flavored Markdown into BBCode for phpBB, vBulletin, MyBB, SMF, and other classic forum software. Headings, bold, italic, strike, links, images, blockquotes, lists, code blocks, and horizontal rules are all mapped to their BBCode equivalents.

Privacy: This tool runs entirely in your browser. Your text is never uploaded, logged, or cached. Close the tab and it's gone. Verify in DevTools → Network: zero requests fire.

Why It's Free (And How We Keep It Free)

Forum BBCode is a 1990s format that everyone still uses. Writing it by hand is painful. The converter runs 100% in your browser.

Markdown to BBCode Converter Features

Here's what this free tool does in detail — every feature is built to solve real problems, runs entirely in your browser, and is free forever.

Full GFM Coverage

Handles headings (mapped to [size=N][b]…[/b][/size]), bold ([b]…[/b]), italic ([i]…[/i]), strikethrough ([s]…[/s]), inline code ([c]…[/c]), fenced code blocks ([code]…[/code] or [code=python]…[/code]), images ([img]…[/img]), links ([url=…]text[/url]), blockquotes ([quote]…[/quote]), unordered lists ([list][*]…[/list]), ordered lists ([list=1][*]…[/list]), and horizontal rules ([hr]).

For the opposite direction, the Free BBCode to Markdown tool converts legacy forum posts back to clean markdown.

Code Block Language Hints

Toggle Code with language to convert \`\`\`python fences into [code=python]…[/code] — some forums (vBulletin with GeSHi, phpBB with the Prism plugin) use the language tag to trigger syntax highlighting. Turn it off if your forum's BBCode parser only supports plain [code]…[/code].

Image Toggle

Uncheck Include images to drop all ![alt](url) references from the output. Useful when posting to a forum that has an image quota or one that strips external images for bandwidth reasons.

Runs 100% Client-Side

Open DevTools → Network and paste Markdown. Zero requests fire. The converter is a regex-based function running inside your browser tab. Your draft never gets uploaded, logged, or cached.

Frequently Asked Questions

Is this Markdown to BBCode tool free?

Yes. Free forever, no account required.

Which forums use BBCode?

phpBB, vBulletin, MyBB, SMF, and many niche community platforms.

What about colors and font sizes?

Markdown doesn't have native syntax for those, so the converter leaves them out. Add [color] and [size] tags manually in the output if your forum supports them.

Does it handle nested lists?

Flat lists yes; complex nested lists may need manual cleanup.

Is my content uploaded?

No. Runs 100% in your browser.
