I recently discovered a great little tool called K2pdfopt for reformatting PDFs such as two-column academic papers so that they are easy to read on a Kindle. (On a related note, it’s ESEM paper review season).
To format for my Kindle Paperwhite, I invoke it like this:
k2pdfopt filename.pdf -dev kpw
Then I just copy the reformatted PDF file to my Kindle. Works great.
Edit: The author of k2pdfopt, William Menninger, informed me that the
"-fc" flag is on by default (no need to specify it), and that you can set
"-dev kpw" in the
K2PDFOPT environment variable so it doesn’t have to be set on the command line each time.
