The blue icon vs the red icon. Which one reigns supreme?
In the office world, there are two kings: The Microsoft Word Document (.docx) and the Portable Document Format (.pdf). But they are not friends. They serve completely different purposes.
Sending the wrong format can make you look unprofessional, or worse, allow someone to accidentally delete your hard work. Here is the definitive guide on when to use which.
| Feature | Word (DOCX) | |
|---|---|---|
| Primary Use | Creation & Editing | Sharing & Archiving |
| Editability | Easy (Designed for it) | Hard (Read-only mostly) |
| Formatting | Dynamic (Can shift) | Static (Locked forever) |
| File Size | Small (Text only) | Varies (Embeds fonts) |
| Security | Low | High (Can Password Protect) |
Winner: PDF.
Never send a resume as a Word doc. Recruiters use Applicant Tracking Systems (ATS). Sometimes Word docs get garbled in these systems. Furthermore, you don't want a recruiter to accidentally hit "Backspace" and delete your phone number.
Winner: Word (DOCX).
If you are writing a contract and need your lawyer to add comments or change clauses, send the Word Doc. PDFs are terrible for collaboration unless you have expensive software.
Winner: PDF.
If you take a Word doc to a print shop, and they don't have the font you used, your poster will look wrong. PDF embeds the font data, so the printer sees exactly what you see.
Think of Word as your kitchen (where you cook the meal) and PDF as the plate (how you serve the meal). You wouldn't serve dinner in a frying pan.
Finished cooking? Plate your meal here.
