PDF vs DOCX: fixed layout or editable document?
A clear, practical comparison with a straight answer.
Send a PDF once the document is finished and needs to look identical everywhere, for contracts, invoices and anything printed. Keep it as DOCX while it is still being written, reviewed or edited by more than one person.
A DOCX is a working document, built to be edited, restructured and commented on. A PDF is a finished snapshot of that document, with fonts and layout locked so it looks identical on any screen or printer.
The two formats sit at different stages of the same file's life. You write and revise in DOCX, then export a PDF once it is ready to be sent, signed or printed.

Frequently asked questions
Should I send a contract as PDF or DOCX?
PDF. It locks the layout so nobody can accidentally change the wording, and it looks the same on every device the recipient opens it on.
How do I edit a PDF like a DOCX?
Convert it to DOCX with a converter, edit it in Word or a similar app, then export back to PDF once you are done.
