Convert Comics Cbr/Cbz to Pdf with AllCbrztoPdf

How to Convert Comics Cbr/Cbz to Pdf with AllCbrztoPdf. One of the most common problems that users face is converting comic image files, such as CBR and CBZ files, to PDF format. To solve this problem, I have created AllCbrztoPdf, a Bash script that greatly simplifies this process.

The script is designed to automatically convert CBR and CBZ files to PDF format using a series of standard Bash commands, making the conversion of large amounts of files a simple and fast task. Running the script is simple. Once executed, it will download and install the necessary programs for distributions such as Debian based and SysLinuxOS, then prompt the user to select a main folder via Zenity and subsequently start converting all CBR and CBZ files to PDF format within the folder and its subfolders. During the conversion, the script will display the progress using pv and create a single combined PDF file using pdftk. Finally, the script will save the resulting PDF file in the same folder where the original file was located. By default, it will only leave the PDF files and DELETE ALL CBR and CBZ files.

Download via GitHub

$ git clone https://github.com/fconidi/AllCbrztoPdf.git
$ cd AllCbrztoPdf/
$ chmod +x allcbrztopdf.sh
$ ./allcbrztopdf.sh

Download via SourceForge

For other linux distributions, the strings with sudo can be commented out/deleted, and the packages can be installed through the package manager. If you want to keep the CBR/CBZ files, just comment out the rm “$file” string at the end.
