Add the 'i' modifier to the end of the regex to enable case insensitivity.
See perldoc perlre
It's covered under the "Modifiers" section near the top.

Yes, the "i" modifier will take care of letter case ( pdf or PDF or even Pdf, pDf, etc.)
But I am not sure that this part or your regex:
really does what you want it to do.
