Getting the best resolution for pdf-documents on the an ebook reader like kindle isn’t always easy, but there’s a great program available for “trimming” your pdfs.
With the Java-based open-source software Briss, you can remove unnecessary margins by cropping the even and odd pages of a pdf-document. The end-result is a pdf-document that better utilize the screenspace of the kindle, and hence bigger fonts to read. Results may vary though as it seems the kindle software does a little bit of optimization itself.
Note: There’s no direct installer or execution but you can create a shortcut yourself for running the program using ‘java -jar briss-x.y.z.jar’, where x.y.z refer to your downloaded version. It’s also assumed that Java Runtime Environment (JRE) is installed on your system.
