epub2cbz

C# program to extract .epub Manga and Comic ebooks into .cbz files, including a ComicInfo.xml file with chapter info, reading direction and more.

Prerequisites

• Epubs must be DRM-free
• They should ideally be in the format of "[Series] v[Volume].epub", for example "Two Pieces v69.epub" (both are optional, but are derived from the filename, if ComicInfo is enabled and calibre tags are not found)
• If you download the smaller package (without "_full" in the filename), you need to install .NET Desktop Runtime 9.0. The program should guide you to the correct website, if it isn't installed yet.

How to

• Start the epub2cbz.exe
• If in File Mode, drag and drop the epub files onto the main text window and optionally select an "Output Folder" (📁)
• If in Folder Mode, click on the "Input Folder" button (📁) and select the folder containing the epub files
• (Click on the mode switch button (🔄) to switch between these two modes)
• Enable or disable certain options, like creating a ComicInfo.xml file or extracting images. The settings menu (⚙) contains more options (recommended settings are enabled by default)
• Click the "Start" button and wait
  

Command Line Arguments

• "--simple" / "-s": Enable "Simple Mode". Only extracts images. No further processing is done. All images keep their original name. Very Fast!
• "--dark" / "-d": Enable dark mode
  
  

Build from Source

Download and install the .NET SDK 9.0 then either run the "publish_full.bat" or "publish_small.bat" in the source folder
