| Title | Browser tabs, search results and file previews | Use a clear title, not the file name |
| Author | Document properties and some search tools | A person or a company name |
| Subject | Document properties | A one-line summary of the file |
| Keywords | Document properties and some search tools | Separate keywords with commas |
Empty fields are left unchanged. To remove metadata completely, use Sanitize PDF.
