LCP DRM removal with GUI

Usage

The tool supports .epub, .pdf, .lcpa audiobook, and .lcpl files. It can be run either via a standalone Windows executable or a Docker container.

If the passphrase is not provided via the command line, the program will attempt to read it from a passphrase.txt file (one passphrase per line). If this file is missing, it will be created automatically, and the program will exit so you can populate it.

For .lcpl files, the publication is downloaded automatically before decryption. Downloaded publications are renamed using their metadata, when available, in the Title-Author format. The decrypted output file will be saved in the same directory as the source file, appended with the _DECRYPTED suffix.

Windows

1. Download the prebuilt executable from the latest GitFlic release.
2. You can use either the Graphical User Interface (GUI) or the command line:

Graphical User Interface (GUI)

• Double-click lcpdedrm.exe (or run .\lcpdedrm.exe --gui).

• Alternatively, if running from Python source:

  python lcpdedrmgui.py
  

• The GUI allows you to select EPUB, PDF, LCPL, and LCPA audiobook files via a file picker, enter passphrases or manage passphrase.txt, choose an output folder, monitor logs in real-time, and open the folder of the decrypted file directly.

Command Line

Open PowerShell or CMD and run:

# With a specific passphrase
.\lcpdedrm.exe "C:\path\input.epub" "YOUR_PASSPHRASE"

# Using the auto-generated passphrase.txt file
.\lcpdedrm.exe "C:\path\input.epub"

(Note: passphrase.txt is read from or created in the same folder as the .exe file).

Docker

You can run the tool directly using the GitFlic Docker image. Mount your current directory to /data so the container can access your files.

# With a specific passphrase
docker run --rm -v "${PWD}:/data" registry.gitflic.ru/project/mikudaio/dedrmlcpatch/lcpdedrm:latest "/data/input.epub" "YOUR_PASSPHRASE"
