"PDFCropperX" is a small application which modifies cropping rectangles of a PDF file.
If you have a scanned PDF file and want to read it using a device with small display (like Amazon Kindle), you may find this software useful.

This software requires Mac OS X Snow Leopard.

This software is freeware. But if you like this software, please install "Search In Amazon Services" and buy some items from Amazon by using them. These are small Automator scripts which bring me some income through Amazon's Associate Program. Of course this is not mandatory. Feel free to use "PDFCropperX" without installing "Search In Amazon Services".
