As a pdf file reader, it does like all other software: neither better nor worse. But for the rest, all the operations are tedious, I haven’t found the solution to convert the file on the screen, each time you have to go through the integrated explorer to process the file on the disk, nothing is intuitive ; I also didn’t understand how to do the OCR of a pdf file.
Installed and uninstalled quickly, it have no interest as a reader, and it is far below, for example, what PdF Element offers, or even PdFX Change Editor.
