Which program can convert a book from DJVU to PDF format. Please advise one's you have tried yourself.
Any of the PDF virtual printers will do this - I use pdfFactory.
For Windows, I recommend PDFCreator, an open source software. You simply print it to the PDFCreator printer.
First, since PDF is a proprietary format, it's always better to always use Adobe Acrobat Reader.
Second, for your case:
- I advise to install SumatraPDF as with it you can open many other documents types beside those of Djvu & PDF, and it's truly light weight.
- If you have already installed Acrobat Reader (or similar) your can Print/Export your Djvu document using the virtual printer that comes with Acrobat Reader (or similar).
- This method will convert your Djvu pages to bitmaps, so forget about maintaining text & etc, and expect that the file size will increase dramatically.
- PDF is optimised for vector graphics while Djvu applies an algorithm for compressing images far below a JPG can achieve (source).
