How do I view the metadata of a PDF?
Upload the file to the viewer at the top of this page and the fields appear in about a second. The tool reads the PDF Info dictionary and any XMP packet, then reports the title, author, subject, keywords, creator, producer, creation and modification dates, page count, page size and PDF version.
What metadata does a PDF file contain?
A PDF carries a title, author, subject and keywords that a person can type, plus creator and producer strings written automatically by the software that made and exported the file. It also stores creation and modification timestamps, the PDF version, page count and page dimensions. Newer files add an XMP packet holding the same information as XML.
How can I see PDF metadata in Windows?
Right click the file in File Explorer, choose Properties, then open the Details tab. Windows shows a shortened set of fields, mainly title, author and dates, and it leaves out the producer string and XMP data. An online viewer shows the full set without installing anything.
How do I check PDF metadata on a Mac?
Open the PDF in Preview and choose Tools, then Show Inspector, or press Command plus I. The General tab lists title, author, creation and modification dates. Preview hides the producer field and the XMP packet, so it gives you a partial picture of what the file stores.
Can PDF metadata reveal who created a document?
Often yes. The author field frequently carries a real name or a network username, and the creator and producer strings name the exact software and version used. Timestamps can also show when a document was drafted and last edited, which is why metadata comes up so often in legal disputes.
Does this tool change or remove the metadata?
No. The viewer only reads the file and reports what it finds, then deletes the uploaded copy once the fields have been extracted. If you need to strip or rewrite metadata before sharing a document, you need a metadata editor or a redaction tool instead.
Why is the author field empty on so many PDFs?
Because nothing forces it to be filled in. Word and Google Docs populate it from the account that created the document, but a PDF exported from a browser, a scanner or a design tool usually leaves it blank. An empty author field tells you something about how the file was made rather than being a fault.
What is the difference between the Creator and Producer fields?
Creator names the program the document was originally written in, such as a word processor. Producer names the component that wrote the actual PDF file, which is often a separate library. A document written in Word and exported through a print driver will show one name in Creator and a different one in Producer.
