Hi, the file you attached is a jpg file, not a pdf. It can be opened in FlexiPDF though and it can be part of a PDF, but basically it is an image file. As FlexiPDF is not a graphics programme, you can't do image processing in FlexiPDF itself. When you choose the Object tool, then select the image and right-click, the context menu has the menu item "Image" and in the sub menu "Edit..." to open the image in your standard image editing programme and "Edit with..." to select a programme for editing. Correcting brightness, contrast and sharpness gives something like this:

Of course, if you have a great number of image files, this is a tedious procedure. It would be easier then to export all the images from a pdf and use an image editing programme with batch function to edit them all at once.
