About PDF Info
PDF Info shows what is hidden inside a file: how many pages it has, how large it is, the page dimensions and the author, title, software and dates stored in its properties.
Quickly see how many pages a PDF has, how big it is, and who made it. Handy before sending a file, because the author and software fields can reveal more than you expect.
