MD vs RST — Differences, File Size & When to Use Each

Q: How do I convert Markdown to PDF?

Use KaijuConverter&#039;s Markdown-to-PDF converter, or command-line Pandoc (the gold standard — installed with one command, converts MD to PDF/HTML/DOCX/EPUB in a single line). VS Code with Markdown PDF extension also works locally.

Q: Markdown vs HTML: which should I write in?

Markdown for almost everything — it&#039;s 10× faster to write, version-control-friendly, and compiles to HTML automatically. Write raw HTML only when you need fine control over layout, embedded JavaScript, or features Markdown doesn&#039;t support (complex tables, forms). Static-site generators (Hugo, Astro, Jekyll) compile MD to HTML for you.

Comparativo de vantagens

MD Vantagens

Readable as plain text even before rendering — fits in version control beautifully.
Dead-simple: 90% of needs covered in 10 minutes of learning.
Converts trivially to HTML, PDF, EPUB, and DOCX via Pandoc.
Every modern IDE, note-taking app, and developer tool renders it natively.
Lightweight — a typical Markdown file is kilobytes, not megabytes.

RST Vantagens

Rich directives for admonitions, code, math, and custom elements.
Cross-references work within and across documents.
Sphinx ecosystem offers best-in-class Python docs output.
Standardized as part of Python PEP infrastructure.
Plain text, version-controllable.

Limitações

MD Limitações

No formal authoritative spec — CommonMark, GFM, and MultiMarkdown differ on edge cases.
Tables and complex layouts are clunky; footnotes and math require extensions.
Links to images stay external — no embedded media unless you base64-inline.
Styling is limited to what HTML allows — custom branding requires CSS outside Markdown.

RST Limitações

Syntax denser than Markdown — higher learning curve.
Less widely adopted than Markdown outside Python world.
Multiple directive dialects (Sphinx, Docutils, custom) create fragmentation.
MyST (Markdown + Sphinx) has pulled many Python projects toward Markdown.

Perguntas frequentes

Markdown is a lightweight text-based markup language created by John Gruber and Aaron Swartz in 2004. A .md file uses simple conventions (*italic*, **bold**, # headings, - lists) that compile to HTML. It became the default writing format for GitHub READMEs, Stack Overflow posts, Discord messages, and most developer documentation.

Markdown files are plain text — open in any text editor. For formatted preview use VS Code (built-in preview), Typora, Obsidian, or upload to GitHub/GitLab which render Markdown automatically. Every note-taking app (Notion, Bear, Joplin) handles Markdown natively.

Use KaijuConverter's Markdown-to-PDF converter, or command-line Pandoc (the gold standard — installed with one command, converts MD to PDF/HTML/DOCX/EPUB in a single line). VS Code with Markdown PDF extension also works locally.

Markdown never had a formal spec for its first decade. CommonMark (2014) and GitHub Flavored Markdown (2017) standardized the core syntax, but edge cases (nested lists, HTML embedding, table syntax) still differ across renderers. For portability, stick to basic GFM features.

Yes — most modern doc tools are built on Markdown. MkDocs, Docusaurus, Astro Starlight, GitBook, and Read the Docs all accept Markdown input. For documentation needing rich features (tabs, callouts, versioning), MDX (Markdown + JSX components) extends MD with React-style embeds.
