PDF vs Word: Which Format Should You Use?

Compare PDF and Word (DOCX): when to use each format, pros and cons, and how to convert between them.

PDF and Microsoft Word (DOCX) are the two most common document formats. They solve different problems: PDF locks in appearance for sharing; Word keeps content editable for ongoing work.

When to use PDF

• Final documents: contracts, invoices, forms and reports
• Sharing with people who should not edit the content
• Printing — layout stays identical on every printer
• Archiving — PDF is an open ISO standard

When to use Word

• Drafting and editing text with track changes
• Collaborating with comments and suggestions
• Documents that need frequent updates
• Mail merge and template-based workflows

How to switch between them
