  3. (Optional) create some post-prosssing command and put into config.json's postprocessing key. Remember to add quotes and escape special characters if needed! You can check the example config-example.json to get an idea.
  4. Install Python3, and then pycryptodome (pip install pycryptodome)

  1. Clone the repo.
  2. Install calibre and edit config.json's calibre key to your calibre-debug.exe path.
  3. (Optional) create some post-prosssing command and put into config.json's postprocessing key. Remember to add quotes and escape special characters if needed! You can check the sample config.json to get an idea.
  4. Clone https://github.com/apprenticeharper/DeDRM_tools repo and place "DeDRM_plugin" folder and its content directly into this repo's root folder.

Usage

usage: extract_kindle.py [-h] [-k] [-p] [-o OUTPUT] dir

positional arguments:
  dir                   choose the folder contains DRMed azw file(s)

optional arguments:
  -h, --help            show this help message and exit
  -k, --keep            keep temp and useless files
  -p, --postprocessing  do some postprocessing with the file.
  -o OUTPUT, --output OUTPUT
                        output folder (default: same as dir)

Examples:

extract_kindle.py "G:\_temp\My Kindle Content\B00KYFFDV2_EBOK" -o "D:\output" -p
extract_kindle.py "G:\_temp\My Kindle Content\B00KYFFDV2_EBOK"

You can also use it as a module by something like

extract_kindle.main(R"G:\_temp\My Kindle Content\B00KYFFDV2_EBOK", "-o", "D:\\output", "-p")

Post-processing template string substitution

Remember to add quotes around them if needed!

  • $o: output root path (i.e. -o parameter)
  • $f: book name string (path-safe, extracted from Kindle info)
  • $p: full path of the folder contains the image files (basically, $o/$f)
