If your ebook reader supports EPUB you might be better of extracting the images from the PDF and DjVu files and creating EPUB files from the resized images.

This of course depends on the handling of larger-then-screen images on your reader, if that is different for EPUB than for images embedded in PDF, then of course you should target the better supported format (with regards to zooming and panning). A series of images in an EPUB file are easier to extract than the corresponding images from a PDF stream. So the handling on your ebook reader should be faster. At least on the systems I tested that is the case ( Sony PRS-700, Sony PRS-T1, Cybook Odyssey HD).

For the actual extraction, scaling and recombination I use a Python based program on Linux that drives standard tools like pdfimages and ddjvu for the extraction, imagemagick for the scaling/conversion, and does the recombination into EPUB itself.

Of course the last step could easily be changed to the recombination into a PDF file using reportlab.
