I am trying to convert djvu documents to pdf documents. The documents are books and they need to be batch converted.
All djvu to pdf converters I have used, including the ddjvu utility, a-pdf-2-djvu, online converters and other converters have the problem that text quality is significantly diminished when converting to pdf.
You can notice the same thing when converting djvu to tif.
The Zebradoc djvu converter claims to fix that problem:
