Convert Markdown to Wikipedia / MediaWiki wiki markup. Tables, images, internal links, syntax highlighting.
Free Markdown to MediaWiki Converter translates GFM Markdown into the exact wikitext used by Wikipedia, Wikimedia Commons, Fandom, and any self-hosted MediaWiki installation. Headings become == Equals ==, bold becomes '''triple apostrophes''', links become [url text] or [[Internal|alias]], and tables become wikitables with class='wikitable'.

If you're a wiki editor, you already spend a lot of time on wikis. Adding a paywall tool to the workflow is absurd. This converter runs entirely in your browser and a single ad pays the hosting.
| Input | Output | Typical size | Speed | Login needed |

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.
Heading levels H1–H6 become = Equals = / == Equals == / … / ====== Equals ======. Bold **x** becomes '''x'''. Italic *x* becomes ''x''. Strikethrough ~~x~~ becomes <s>x</s>. External links [text](url) become [url text], which is exactly how MediaWiki expects external links.

By default, Markdown image syntax  becomes a MediaWiki file embed [[File:file.jpg|thumb|alt]] — the format every Wikimedia wiki expects. Toggle Images as files off if you want plain external image links instead.
For docs that emphasize images, pair with the Free Markdown Image Extractor to audit your image references first.
GFM pipe tables become wikitables wrapped with {| class='wikitable' / |}, with ! for header cells and |- for row separators. Column alignment is preserved. The output pastes cleanly into Wikipedia's source editor and renders with the standard table styling.
Clean up your tables first with the Free Markdown Table Sorter to get them into the right order before conversion.
Fenced Markdown code blocks become <syntaxhighlight lang='js'> blocks — the tag provided by the SyntaxHighlight MediaWiki extension that ships enabled on Wikipedia and almost every other MediaWiki installation. Toggle Use syntaxhighlight off to fall back to plain <pre> blocks.
For BBCode-based forums, try the Free Markdown to BBCode Converter.

The defaults match Wikipedia — syntax highlighting on, file embeds on. Change them if your wiki uses a different setup.
Copy the output and paste directly into any MediaWiki source editor. Preview before saving.
Write articles in Markdown for speed, then convert to wikitext for publishing.

Yes. Free forever, no account required.
Yes. The output is standard MediaWiki wikitext and pastes into Wikipedia's source editor without modification.
External links become [url text] format. For internal [[Page|alias]] links, you'll need to rewrite them manually — the converter can't guess which pages exist on your wiki.
Category tags [[Category:Name]] aren't generated automatically — add them at the bottom of the wikitext after conversion.
No. Runs 100% in your browser.
