Rather than select settings from a menu each time you run k2pdfopt, if you have settings you want to use each time, or if you don't want to be prompted with a menu, you can specify the settings as command-line arguments as shown below.
  • Create a shortcut icon by right-clicking on the program icon and selecting "Create Shortcut."


  • Right-click the new shortcut icon and select "Properties".


  • Where it says "Target:", append your customized command line options. For example, appending -ui- -j 0 -w 480 -h 800 -bpc 2 will run k2pdfopt with no prompting (-ui-), left-justified text (-j 0), an output screen resolution of 480 x 800, and using 4-level grayscale output (-bpc 2). Be sure to put a space between the name of the program and your command line options as shown in the example below (and if the program name ends in a double-quote, as also shown below, put your options after the double-quote).


  • Click "OK".
  • Re-name the shortcut as you wish.


  • Now you can drop your PDF files onto your new re-named shortcut icon and k2pdfopt will run with the customized settings.


This is a good way to create specific icons for different types of conversions.

Some examples of command-line customized settings:

  -odpi 250
   (Magnified output--see DPI settings.)

  -idpi 400 -w 640 -h 960 -odpi 326
   (Output for the iphone 4 at full 640x960 resolution)

You can see a list of all command-line options here.
