PDF vs DOCX
PDF fixes the layout, so it looks the same on every device and is the right format for anything final: contracts, invoices, submissions. DOCX is editable and reflows, which is what you want while the document is still being written. Send PDF, edit DOCX.
Side by side
| Spec | DOCX | |
|---|---|---|
| Type | Document | Document |
| Extensions | .docx | |
| Introduced | 1993 | 2007 |
| Compression | Both | Lossless |
| MIME type | application/pdf | application/vnd.openxmlformats-officedocument.wordprocessingml.document |
| Use it when | The layout must not change: contracts, invoices, reports, print-ready files. | A document is still being written, reviewed or collaborated on. |
| Avoid it when | The content is still being written or needs to reflow. Keep it in DOCX or Markdown until final. | Sending a final deliverable where layout must be guaranteed. Export to PDF. |
Where the usual answer breaks
Forms people have to fill in. A PDF form is fiddly to complete on a phone; a DOCX is not, if the recipient has Word.
- Layout, fonts and pagination are identical everywhere
- Supports digital signatures, encryption and form fields
- PDF/A is a recognised standard for long-term archiving
- Hard to edit, because it describes a page rather than a document structure
- Reflows badly on small screens
- Text in a scanned PDF is just an image until OCR is run
DOCX
- Editable, with tracked changes, comments and styles
- Open standard, so many applications can read and write it
- Content reflows to fit the screen or page
- Layout can shift between applications and platforms
- Not suitable as a final, fixed-layout deliverable
