PDF and DOCX explained
PDF describes a page as a fixed arrangement of text, vector graphics and images. Unlike a word processor document, it is designed so the page looks identical everywhere — which is exactly why it is awkward to edit.
DOCX is a ZIP archive containing XML that describes a Word document's content and formatting. Renaming one to .zip and opening it shows the structure directly.
- Where PDF files come from
- Contracts, invoices, reports, forms, academic papers and scanned documents.
