New Post: Does Ghostscript.NET supports multiple page TIFFS?

You should try one of the following devices which for sure supports multipage pdf to multipage tiff: tiffg4, tiff24nc, tiff32nc

1. The tiffg4 one is grayscale and uses a resolution of 204dpi by 196dpi (as the TIFF G4 fax standard requires).
2. The tiff24nc one is in RGB color (with 8 bits per color component) and uses a resolution of 72dpi by 72dpi.
3. The tiff32nc one is in CMYK color (with 8 bits per color) also using a resolution of 72dpi.
   

Also, would be good if you could post some code and sample files so I can test if mentioned devices doesn't work for you.

Make sure you image viewer supports multipage tiff preview (as there are a lot of them that doesn't) as I don't want you to get confused if the pdf is multipage or not.
