The Short Answer

  • Use PDF when the document is final and should not be edited
  • Use Word when the recipient needs to edit or fill in content
  • PDFs look identical on every device; Word files can reflow differently
  • PDF is better for printing, sharing, and formal submissions

When to Use PDF

PDF is the right choice when: sending a CV or resume (you want it to look exactly as designed), submitting forms or contracts, sharing a report or whitepaper for reading (not editing), printing documents, archiving important records. The key advantage is that a PDF looks identical regardless of the device, OS, or software the recipient uses.

When to Use Word

Word (.docx) is better when: you're collaborating and need track changes, the recipient needs to fill in a template, you're still drafting and the document will be revised, or the recipient uses the content inside another Word document. The downside is that fonts and layout can shift if the recipient doesn't have the same fonts installed.

A good rule of thumb: draft in Word, distribute as PDF. When your document is final, convert it to PDF before sending. FileMagics can convert Word to PDF (or PDF back to Word) for free in seconds.
