Tried with: Foxit Reader 7., WinDjView 2.#!/usr/bin/env python3 # Convert DJVU to PDF with table of contents, if available. You would need to run it through a OCR tool to get text embedded in the PDF. Note that the resulting PDF does not have OCR. I did not see much reduction in filesize by using 300 or 200 DPI. Note that the settings of the Foxit Reader PDF Printer did not seem to have much effect on the file size. This will use the Foxit PDF Printer to write a PDF file for you. For the print settings, choose a page size (Letter) and remember to choose Scale to fit media. This printer has settings that you can modify. In the printer list, choose Foxit Reader PDF Printer. This also installs a PDF Printer which we will use for conversion.

All these methods result in PDF file sizes that are quite large, in hundreds of MBs. There are several ways to convert DjVu file to PDF.
