Preview has a pretty clean and efficient PDF editor, especially when it comes to adding and removing pages.
What I'm really looking for is a function that can remove duplicate pages.
I've got a pdf with tons of duplicate pages and it would be really great if there was an option to remove all doubles.
Any ideas?
For the command-line I can recommend:
pdftk, the PDF Toolkit (for the Snow-Leopard installer you can try Pacifist to get the binaries or use the older version)
Merge PDF Documents
Split PDF Pages into a New Document
Rotate PDF Pages or Documents
…
If your PDF is edit-protected, you may want to try qpdf (via e.g. homebrew) to remove the restrictions first.
QPDF is a command-line program that does structural, content-preserving transformations on PDF files. It could have been called something like pdf-to-pdf. It also provides many useful capabilities to developers of PDF-producing software or for people who just want to look at the innards of a PDF file to learn more about how they work.
Cmd-Click on the title gives you the full path. This not only works in Preview but more or less in all applications (including Office).

Click 'View' in the toolbar > Thumbnails. Then highlight the duplicated page, press delete to remove it.
