PDF or Word? It sounds simple — but choosing the wrong format causes real problems. Documents that cannot be edited when they need to be. Files that look different on every device. Contracts that get modified after signing. Resumes that break when opened on a different computer.
The Core Difference Between PDF and Word
A Word document is a living, editable file. Text, images, tables, and formatting are stored as objects that any word processor can read, modify, and re-export. Word is for creating and editing.
A PDF is a fixed-layout document. Content is converted to a format that looks identical on every device, regardless of fonts installed, Word version, or whether the recipient has any word processor. PDF is for sharing and archiving.
When to Use PDF
Use PDF when sharing finished documents. Contracts, invoices, reports, certificates, and resumes should look identical for every recipient and should not be accidentally changed.
Use PDF when you do not control the recipient's software. A Word document may look different in an older version of Word, in Google Docs, or in LibreOffice. A PDF looks identical everywhere.
Use PDF when protecting content. PDF files can be password-protected. Word documents offer much weaker protection.
Use PDF for formal submissions. Job applications, university submissions, government forms, legal filings — PDF guarantees what you submit is exactly what the recipient receives.
When to Use Word
Use Word when still working on the document. The editing experience in Word is far superior to any PDF editor.
Use Word when collaborating. Track changes and comments are purpose-built for collaborative editing.
Use Word when the recipient needs to edit the content. Templates, drafts, and documents that will be incorporated into larger files should stay in Word until finalised.
Common Situations — PDF or Word?

| Resume or CV | PDF always |

| Draft report for review | Word until final, then PDF |
| Invoice | |
| Template someone will customise | Word |
| Email attachment | PDF (smaller, universal) |
