Quick Verdict
Use PDF when…
Use PDF for contracts, forms, brochures, and documents that must look identical everywhere — printing, email attachments, legal documents. PDF preserves your layout with pixel-perfect fidelity.
Use HTML when…
Use HTML for web content, documentation, and anything that should be searchable, linkable, accessible, and responsive. HTML renders correctly on every screen size and works with screen readers natively.

Frequently asked questions
Should I publish documentation as PDF or HTML?
HTML is almost always better for documentation. It's searchable, linkable, responsive, and accessible. Users can ctrl+F within a page, follow links between pages, and read on any device. Reserve PDF for downloadable reference guides or print-ready versions. Docusaurus, GitBook, and ReadTheDocs generate excellent HTML docs.
Can Google index PDFs?
Yes — Google indexes PDF content and may rank it in search results. However, HTML pages have significant advantages: faster load times, responsive design, better internal linking, and richer structured data support. For SEO, always prefer HTML and provide PDF as an alternative download.
How do I convert PDF to HTML?
Google Docs can open PDFs and export to HTML. Command line: `pdftohtml input.pdf output.html` (from the Poppler package). Adobe Acrobat: File → Save As → HTML Web Page. Note: PDF-to-HTML conversion quality varies — simple text documents convert well, but complex multi-column layouts often produce messy HTML.
