Kindle+Briss for PDFs

While the Kindle does support PDFs natively, readability has been a problem for me. I generally have to rotate the Kindle 90 degrees to get the text large enough to read.

Briss is a cleverly named PDF cropping program. Briss can crop away the page numbers and headers/footers of your PDF eBooks before you run them through a conversion program to create an ePub or Mobi book. That's great by itself.

But another cool feature is the ability to make two simultaneous crops per page. So, you can select the top half of the page and the bottom half of the page in distinct cropping boxes. With this, you create a new PDF with twice as many pages which will display in a larger, more readable form. OR, you can use it to take care of text in columns.

Very useful, free, and multiplatform. What more could you want?
