Encryption that restricts how a purchased file can be copied or converted.

Digital rights management explained

Ebook and media stores commonly wrap files in DRM, notably Adobe ADEPT for EPUB and PDF and proprietary schemes for audiobooks and video.

A DRM-protected file is encrypted, so a converter sees ciphertext rather than content and fails with a parse error rather than producing bad output.

DRM-free purchases and library exports convert normally.
