From Indie Softworks:
CBR and CBZ to PDF is a small application designed to help users enjoy their favorite media. This program quickly converts CBR, CBZ, ZIP, and RAR files to PDFs for convenient reading on many devices. CBR and CBZ files are common comic book archives. These archives are very similar to RAR and ZIP archives respectively - which is a primary reason this application supports them as well. Often times they're read using special software. However this software may not be available or may not run efficiently on your favorite platform. That's the primary reason we made this software. The conversion process is very simple. First click the Browse button to find your archive. You may also type or paste the location in manually. Then click Convert. This will bring up a prompt asking you where you'd like to save your PDF. After clicking Save the conversion process will begin. It's that easy. Once conversion is complete, you can click the Open PDF Location button to open the location of your most recent PDF.
