These files contain textual and graphical information similar to one found in word processing documents but in a form that is print-ready. Document is called print-ready when layout of all the elements on the page is finalized, colors are proofed and separated etc. Publisher documents lack such interactive features as hyperlinks and clickable table of contents.

Another program that uses file extension PUB is "Pretty Good Privacy" (PGP) cryptography application. It uses these files for storing public portions of asymmetrical encryption/decryption keys.
