Convert MediaWiki to HTML

Why Convert MediaWiki to HTML?

Converting MediaWiki markup to HTML is the most natural transformation for wiki content because HTML is the format that MediaWiki software itself generates when rendering pages for browsers. By converting directly to HTML files, you get standalone web pages that can be viewed in any browser without requiring a MediaWiki installation, making your content portable and universally accessible.

MediaWiki markup is a shorthand notation that simplifies content creation for wiki contributors. The syntax == heading == becomes <h2>heading</h2>, triple apostrophes for bold become <b> tags, wiki links become <a> hyperlinks, and complex wiki table syntax is transformed into standard HTML tables with proper <table>, <tr>, and <td> elements. The resulting HTML preserves all the semantic structure of the original wiki content.

HTML conversion is essential for migrating wiki content to non-wiki platforms. If you are moving documentation from a MediaWiki installation to a static website, a CMS like WordPress, or a documentation platform like ReadTheDocs, HTML provides the intermediate format that these platforms can ingest. The clean, semantic HTML output makes it easy to apply CSS styling to match your target site's design.

For archival purposes, converting MediaWiki to HTML creates self-contained files that will remain readable indefinitely. HTML has been the standard markup language of the web since 1991, and every computer with a browser can display HTML files. This makes HTML an excellent long-term preservation format for wiki content, free from dependency on any particular wiki software or database.

Key Benefits of Converting MediaWiki to HTML:

• Universal Viewing: Opens in any web browser on any device
• No Software Required: No MediaWiki installation needed to read content
• SEO Ready: Search engines can index HTML pages directly
• CSS Styling: Apply any visual design with stylesheets
• Platform Migration: Import into any CMS or static site generator
• Long-Term Archival: HTML will remain readable for decades
• JavaScript Enhancement: Add interactivity to static wiki content

Practical Examples

Example 1: Wiki Article to Web Page

Input MediaWiki file (article.mediawiki):

== Solar System ==

The '''Solar System''' consists of the
[[Sun]] and everything that orbits it.

=== Inner Planets ===
* [[Mercury (planet)|Mercury]]
* [[Venus]]
* [[Earth]]
* [[Mars]]

''See also:'' [https://nasa.gov NASA]

Output HTML file (article.html):

<h2>Solar System</h2>
<p>The <b>Solar System</b> consists
of the <a href="Sun.html">Sun</a>
and everything that orbits it.</p>
<h3>Inner Planets</h3>
<ul>
  <li><a href="Mercury.html">Mercury</a></li>
  <li><a href="Venus.html">Venus</a></li>
  <li><a href="Earth.html">Earth</a></li>
  <li><a href="Mars.html">Mars</a></li>
</ul>

Example 2: Wiki Table to HTML Table

Input MediaWiki file (data.mediawiki):

== Server Status ==

{| class="wikitable"
|-
! Server !! Status !! Uptime
|-
| Production || {{Green|Online}} || 99.9%
|-
| Staging || {{Yellow|Degraded}} || 98.5%
|-
| Development || {{Green|Online}} || 99.1%
|}

Output HTML file (data.html):

<h2>Server Status</h2>
<table class="wikitable">
  <tr>
    <th>Server</th>
    <th>Status</th>
    <th>Uptime</th>
  </tr>
  <tr>
    <td>Production</td>
    <td><span class="green">Online</span></td>
    <td>99.9%</td>
  </tr>
  ...
</table>

Example 3: Documentation Migration

Input MediaWiki file (docs.mediawiki):

== Installation Guide ==

=== Requirements ===
# Python 3.8 or higher
# pip package manager
# Virtual environment (recommended)

=== Quick Start ===
 pip install mypackage
 python -m mypackage init

{{Warning|Always back up your data
before upgrading.}}

✓ <ol> numbered requirements list
✓ <pre> code blocks for commands
✓ Warning template as styled <div>
✓ Ready for any CSS framework

Frequently Asked Questions (FAQ)

Q: How does MediaWiki markup relate to HTML?

A: MediaWiki markup is essentially a simplified shorthand for HTML. The MediaWiki software converts wiki syntax to HTML when displaying pages in a browser. For example, == heading == becomes <h2>, '''bold''' becomes <b>, and [[link]] becomes <a href="...">. Converting MediaWiki to HTML produces the same output that the wiki engine would generate, but as standalone files.

Q: Will the HTML output include CSS styling?

A: The converted HTML includes the structural markup with appropriate class attributes (like "wikitable" for tables), but does not embed MediaWiki's full CSS theme. You can apply your own CSS stylesheet to the output, or use the MediaWiki default styles. The HTML is designed to be clean and semantic, making it easy to style with any CSS framework like Bootstrap, Tailwind, or custom stylesheets.

Q: How are wiki templates handled in the HTML conversion?

A: Wiki templates are expanded to their rendered HTML output. Since HTML does not have a template transclusion system, the final rendered content of each template is embedded directly in the HTML. Common templates like infoboxes, navigation boxes, and warning messages are converted to styled <div> elements with appropriate CSS classes for easy styling.

Q: Can I use the HTML output in WordPress or other CMS platforms?

A: Yes! The clean HTML output is perfect for importing into WordPress, Drupal, Joomla, Ghost, or any CMS that accepts HTML content. Simply copy the body content into your CMS editor's HTML mode. The semantic markup (headings, lists, tables, links) is preserved and will work with your CMS's theme and styling. This is one of the most common reasons for converting MediaWiki to HTML.

Q: How are internal wiki links converted?

A: Internal wiki links ([[Page Name]]) are converted to HTML hyperlinks (<a href="Page_Name.html">). The link targets are formatted as local file references, making them work when the HTML files are in the same directory. You can adjust the link format for your deployment environment. External links ([https://...]) are preserved as standard HTML hyperlinks with their original URLs.

Q: Is the HTML5 or XHTML output format used?

A: The converter produces HTML5 output by default, using the <!DOCTYPE html> declaration and modern semantic elements. HTML5 is the current web standard supported by all browsers. If you need XHTML output for XML-strict environments, the content is compatible with XHTML since it uses proper closing tags and valid nesting. The output validates against HTML5 standards.

Q: Can I convert MediaWiki with embedded HTML to pure HTML?

A: Yes. MediaWiki allows inline HTML in wiki markup, and these HTML elements are preserved in the conversion. The converter merges the wiki-generated HTML with any inline HTML from the source, producing a clean, unified HTML document. HTML elements like <div>, <span>, <ref>, and custom tags are processed according to MediaWiki's HTML sanitization rules.

Q: Does the conversion support MediaWiki extensions like Cite and Math?

A: Common MediaWiki extensions are supported. The Cite extension's <ref> tags are converted to HTML footnotes with numbered superscript links. The Math extension's LaTeX formulas are converted to HTML representations or MathML where supported. ParserFunctions and other programmatic extensions are evaluated to their output text. Extension-specific markup that cannot be resolved is preserved as readable text.
