HTML vs MEDIAWIKI
HTML Document と MediaWiki Markup を徹底比較 — ファイルサイズ、品質、互換性、そして用途に応じた最適なフォーマットの選び方を解説します。
HTML Document
Documents & TextHTML is the standard markup language for web pages. As a conversion target or source, it carries text content with structural and formatting information that can be extracted or repurposed.
HTML ファイルについてMediaWiki Markup
Documents & TextMediaWiki markup is the wikitext syntax used by Wikipedia and thousands of MediaWiki-powered wikis. It provides formatting for links, tables, templates, categories, and references, powering one of the largest collaborative content systems.
MEDIAWIKI ファイルについて長所の比較
HTML 長所
- Universal — every browser, OS, email client, and document reader displays HTML.
- Plain text, human-readable, grep-able, and diffable in git.
- Flexible — pages render even with broken or partial markup (error-tolerant parser).
- Carries structure, styling (CSS), and behavior (JavaScript) in one file.
- Accessibility-friendly when written with semantic tags and ARIA attributes.
MEDIAWIKI 長所
- Powers Wikipedia — battle-tested at planet scale.
- Templates enable reusable content blocks.
- Internal links, categories, and interwiki references work out of the box.
- Huge existing tooling and translation ecosystem.
制限・弱点
HTML 制限・弱点
- Error tolerance allows sloppy markup to hide real bugs.
- Rendering depends on browser engine — pixel-perfect cross-browser output is an art form.
- Security-sensitive — unsafe HTML can execute scripts or leak data (XSS vulnerabilities).
- File size for equivalent structured data is larger than JSON or XML due to tag verbosity.
- No built-in typing or schema — contract between server and client is informal.
MEDIAWIKI 制限・弱点
- Parsing is notoriously hard — context-sensitive by design.
- Authoring requires learning the unique syntax.
- Lacks standardization — no formal spec, just the MediaWiki implementation.
- Markdown has eroded wiki use cases for smaller projects.

よくある 質問
HTML (HyperText Markup Language) is the core language of the web, created by Tim Berners-Lee in 1993. An HTML file is plain text describing structure (headings, paragraphs, links, images), optionally with styling (CSS) and interactivity (JavaScript). Every web page you visit is rendered from HTML.
HTML files open in every web browser by double-clicking. To edit, use any text editor (Notepad, VS Code, Sublime Text) or a visual editor (Dreamweaver, Pinegrow). Mobile browsers also render HTML files from local storage.
Use KaijuConverter's HTML-to-PDF converter, or print the page from your browser and choose "Save as PDF". For pixel-perfect conversion with page breaks, dedicated tools like wkhtmltopdf or Puppeteer give more control.
Markdown for authoring — it's faster to write, version-control-friendly, and renders to HTML via static-site generators. HTML for delivery and complex layouts where you need full control over styling, forms, and interactivity. Most modern blogs write in Markdown and publish as HTML.
Browsers implement CSS and JavaScript slightly differently, especially for cutting-edge features. Use a CSS reset, test in Chrome/Firefox/Safari, and tools like caniuse.com to check browser support. Modern frameworks (Tailwind, Bootstrap) normalize most cross-browser quirks automatically.
HTML itself is safe, but embedded JavaScript can perform malicious actions (redirects, form hijacking, cryptomining). Only open HTML attachments from trusted sources. Modern browsers sandbox local HTML files to limit their access to your system.
