krop – simple graphical tool to crop the pages of PDF files

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.

Features include:

  • Automatically split pages into subpages to fit the limited screen size of devices such as eReaders. This is particularly useful, if your eReader does not support convenient scrolling.
  • Uses Ghostscript to optionally optimize the final PDF.
  • Selections apply to all pages, even/odd pages, or individual pages. Specify pages which require individual selections.
  • Fit screen of device:
    • Generic (don’t break pages into arts).
    • 4:3 eReader.
    • 4:3 eReader (widescreen).
    • Nook 1st edition.
    • Nook 1st edition (widescreen).
    • Custom.
  • Rotate final PDF.
  • Use krop on the command line to extract certain pages, rotate pages, and trim empty margins.
  • snap package is available.
