How to convert DJVU to PDF

DjVuLibre provides open source libraries, commandline tools and GUI tools for dealing with DJVU files. So all solutions for converting a DJVU file to a PDF file will use DjVuLibre in some form.

Note that it looks like all conversion options seem to produce PDF by converting every DJVU page into an image. So, the resulting PDF files will be big and much larger than the original DJVU files. There seems to be no way to produce smaller PDF files.

Using ddjvu

• Install DjVuLibre tools on Ubuntu:

$ sudo apt install djvulibre-bin

• Convert using the ddjvu tool:

$ ddjvu -format=pdf in.djvu out.pdf

• To view information about each page in DJVU while it converts:

$ ddjvu -format=pdf -verbose in.djvu out.pdf

• To specify the DPI to use for each page:

$ ddjvu -format=pdf -mag=300 in.djvu out.pdf

Tried with: Ubuntu 18.04

$ sudo apt install djvulibre-bin ghostscript

• Convert DJVU to Postscript:

Using DJView

To convert a DJVU document to a PDF document:

1. Install DjVuLibre DJView.

2. Open the DJVU document in DJView.

3. Choose File → Export as

4. In the Export dialog choose PDF document, the PDF filename and path and press OK.

Note that the PDF export option seems to be missing in recent versions of DJView.
