PDF vs DOCX

DOCX to write, PDF to send — one is the document, the other is a picture of it.

Choose PDF when

Anything final — a contract, an invoice, a CV, a report. A PDF looks the same everywhere and cannot be edited by accident.

Choose DOCX when

Anything still being written or meant to be edited by somebody else. A PDF is a picture of a document; a DOCX is the document.

The thing that catches people out

Converting a PDF back to DOCX recovers text, not layout. Anything laid out with care comes back approximately, and the more designed it was the worse the approximation.
