I have downloaded file which is in djvu format. I want to convert it to pdf or some other more common format, so I can read the document from other devices (e.g. my phone etc).

I found a conversion utility at Lizardtech, but when I converted the doc using the lizardtech software, every page had a watermark - which rendered the converted doc virtually useless.

Does anyone know where I can get a free conversion utility that does not watermark the converted doc?

If your djvu viewer has print button, all you need is CutePDF.. –  tumchaaditya May 10 '13 at 13:38
    
The only thing missing from the solutions below is a GUI (rather than command line) method for batch conversion. –  Jess Riedel Oct 11 at 17:31

Try the online converter

http://www.djvu-pdf.com

It is working fine for many types of DjVu files and should be easy to use...

For DjVu viewer, you can use File » Export as… » PDF format. I think it's easier.

No watermarks, worked perfectly. –  Stephen Jun 6 '12 at 16:35
    
I'm not sure if this is the viewer in question, but it does seem to have working PDF export: sourceforge.net/projects/djvu –  seanf Sep 18 '12 at 15:17
    
This is the easiest and best solution. Very fast, and it's possible to tweak the conversion (i.e. change the resolution by specifying the DPI, or the quality of the JPEG conversion). –  Jess Riedel Oct 11 at 17:31

Short Solution http://0x2a.at/s/projects/djvu2pdf

For those interested or for those that like using the terminal on a Mac

I recently asked this question when I found a strange file on my computer whilst trying to come up with the answer to the same question posed by this thread.

First, install homebrew through the terminal with this

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

And then install djvu2pdf, which, by the way, has almost no documentation but works like a charm.

brew install djvu2pdf

Then, navigate to the directory where my .djvu file is stored, and run this command:

djvu2pdf [somebook.djvu]

Since most textbooks have really long names that have spaces in between them, just enter a little bit of the name (enough to make it so there is only one file in the directory that starts with the current string) and then press tab.

It takes a while, how long I didn't figure out, but definitely not more than half an hour, and it will place a new file in the directory that is a pdf version of the .djvu file.

whycantstufflikethisalwayswork This is the only method I've found to work.

Does this get rid of the watermarks - thats all I really wanted to know. Have you tried what you suggested yourself, and found the printed doc contains no watermarks? –  Zeta2 Sep 13 '10 at 18:36

The ddjvu utility from the DjVuLibre suite seems to do a good job. Here's a small example:

ddjvu -format=pdf <input>.djvu <output>.pdf

Open your Djvu file with the opensource application "SumatraPDF" (which can read Djvu format) and then use your favorite virtual PDF printer to save it as a pdf file.

Wikipedia commons page on Help:Creating a DjVu file has notes on working with DjVu files.
And, the djvu sourceforge page has additional open-source tool reference.

DjVu (pronounced "déjà vu") a set of compression technologies, a file format, and a software platform for the delivery over the Web of digital documents, scanned documents, and high resolution images.

Converting DjVu to PDF (for general reference, you seem to have already checked it):

  1. Download and install Universal Document Converter software onto your computer.
  2. Install DjVu Browser Plugin for Internet Explorer from the Lizardtech site.
  3. Open the DjVu file in Internet Explorer and press the Print button in the DjVu Browser Plugin toolbar
  4. Select Universal Document Converter from the list of printers and press the Properties button.
  5. On the settings panel, click Load Properties.
  6. Use the Open dialog to select "Text document to PDF.xml" and click Open.
  7. Press OK in the Lizardtech plugin Print dialog to start converting. When the PDF file is ready, it will be saved to the 'My Documents\UDC Output Files' folder by default
  8. The converted document will then be opened in Adobe Acrobat or another viewer associated with PDF files on your computer.

Alternately, look at the standalone viewer for DjVu files, DjView4,
or investigate the DjVu sourceforge page for a suitable tool.
