krop is a simple graphical tool to crop the pages of PDF files and can automatically split pages to fit the screen of e-book readers.
krop only adjusts which parts of a PDF are displayed; the original content is still there in the file and will, for instance, show up when editing the file in Inkscape. Using your mouse, you can create one or more selections on the PDF documents. These are the regions that are included in the cropped file. You can create individual selections for each page.
krop is written in Python.
