About This Tool
The title field matters more than most people realise. It is what a browser tab shows, what document management systems index, and what search engines display - so a PDF whose title reads Microsoft Word - untitled2.docx looks careless in every one of those places.
Here you can set the title, author, subject and keywords properly. Keywords are searchable in document systems, which makes them worth filling in for anything that will be filed and retrieved later.
The same tool lets you correct or anonymise the author field, which is the field most likely to carry information you did not mean to publish.

Use Cases
Documents that will be published
A proper title so search results and browser tabs show something meaningful.
Document management systems
Filled-in keywords and subject so the file is findable later.
Anonymising authorship
Replace a personal name with an organisation before distribution.
Frequently Asked Questions
Which field matters most?
Title. Browsers, search engines and document systems all display it, and it is the field most often left as a filename.
Do timestamps change when I edit metadata?
The modification date updates, since the file has been rewritten. Creation date is preserved.
What format should keywords be in?
Comma-separated terms someone might actually search for. There is no strict limit, but a focused list indexes better than a long one.
Can I clear a field completely?
Yes - leave it empty. To strip everything at once, use Remove Metadata.
