2/2 re #OCR
All three were set to #rotate and #deskew. None rotated the page that was sideways, but they all #deskewed pages that needed it. Kofax was the speediest of the bunch, then #OCRmyPDF not far behind and #Foxit was by far the slowest.
File size Foxit produced the smallest file size, #Kofax created files double the original. OCRmyPDF struggled here, ballooning the original size by at least 6 times larger.
