PDF vs Word
PDF and Word documents are two stages of the same workflow. Word (DOCX) is an editable format for writing and revising. PDF is a fixed-layout format for finalising, sharing, and printing. You draft in Word and distribute as PDF.
Use Word while you are still writing or collaborating, because it is fully editable. Convert to PDF when the document is final and must look identical on every device, print correctly, or be signed.

What is PDF and what is Word?
PDF preserves a document exactly as designed — fonts, spacing, images, and vectors — so it looks the same on any device or printer. It is the standard for final documents, invoices, contracts, and forms, and supports digital signatures, but it is deliberately hard to edit.
Word
A Word document (.docx) is a flexible, editable format built for writing. It supports styles, tracked changes, comments, and easy revisions, making it ideal for drafting and collaboration. Its layout can shift if opened on a system with different fonts.
When to use which
Choose PDF
Choose PDF when the document is finished and you need it to print perfectly, look identical everywhere, resist accidental edits, or be signed.
Choose Word
Choose Word while the content is still being written, reviewed, or co-edited, where tracked changes and easy editing matter.
