About DOCX and PDF

Word (DOCX) .docx

Word's modern format: a ZIP archive of XML parts describing text, styles and layout. It has been the default since Office 2007.

Good for

  • Built for editing — text flows and restyles freely
  • Tracked changes, comments and styles
  • Opens in Word, Google Docs, LibreOffice and Pages

Trade-offs

  • Layout shifts between applications and font sets
  • Not a reliable final-delivery format — use PDF for that
  • Complex documents can lose fidelity between editors

application/vnd.openxmlformats-officedocument.wordprocessingml.document

PDF .pdf

A fixed-layout page format. A PDF describes exactly where every glyph and line sits, so it looks identical everywhere — which is precisely what makes it awkward to edit.

Good for

  • Identical layout on every device, screen and printer
  • Embeds its own fonts, so nothing reflows or substitutes
  • The accepted format for contracts, invoices and forms

Trade-offs

  • Not built for editing — text is positioned, not flowing
  • A scanned PDF is just images until text recognition is run
  • Reflows badly on small screens

What changes when you convert DOCX to PDF

It stops being editable

A DOCX is a document that reflows — text finds its own line breaks depending on the fonts and page size available. A PDF fixes every glyph in place. That is exactly why PDF is the format you send someone, and exactly why it is the wrong format to keep working in. Hold on to the DOCX as your editable master.

Rendered by LibreOffice

The conversion runs through headless LibreOffice — the same engine behind the desktop suite, not a lookalike parser. It handles ordinary documents faithfully. Where it can drift is on the elaborate: a document leaning on fonts the server does not have will have them substituted, and the substitute rarely occupies exactly the same width, so line and page breaks can move. Heavily designed layouts are worth checking against the original.

The text stays text

This is not a picture of your document. The words remain selectable and searchable, links stay clickable, and the fonts are embedded so it renders identically on a machine that has never seen them. That is what separates a PDF made this way from one made by scanning a printout — and it is why this is the right way to send a document to someone who only needs to read it.
