Customer Reviews

does not advance through one-page tiffs

I cannot find any feature of this app that is better than the viewer in finder. In particular, it has no tool for advancing from one single-page TIFF to the next.

CPC & Tiff add-in

Bought Tiff add-in and it only opens a portion of the file (oil well log image). Help says to toggle to the next page. Program says there is only one page. Tried multiple Tiffs same result. Useless purchase!


Can finally view JEDMICS and convert .C4 drawings to PDF on my Mac!
