K2pdfopt saves kindle paperwhite with better formatted pdf after conversion, without jailbreak.


./k2pdfopt -as -dev kp2 -jpg 90 -mode fw [filename]
[press ENTER and wait]

Explain params:

  • -as: Autostraighten skewed pages(no need for text pdf)
  • -dev kp2: device is kindle paperwhite 2
  • -jpg 90: compress output file
  • -mode fw: fit width

Optional Options

  • -n: disables text reflow, good for lame pdf reader like Preview.app, not for mobile devices. Smaller output size because “the source PDF’s native content is used along with additional PDF instructions to translate, scale, and crop the source content”.
