The PDF properties feature lets you view and edit the metadata of a PDF document. This metadata includes the document’s title, author, subject, keywords, and dates of creation and modification. It helps in organizing, searching, and managing PDF files more efficiently.
Open a PDF in PDFgear first, then click on the Document Properties function in the Help tab. Now you can view & edit the properties of the PDF in the pop-up window.
