This Python package is a remarkable beast. It doesn't just rely on one method; it attempts to unlock your PDF using multiple tools, including qpdf, PyMuPDF, pikepdf, and pdfcrack, automatically falling back to the next if one fails. For forgotten passwords, it will attempt to bypass weak encryption and can even remember previously discovered passwords to speed up future processing. This "unlock without password" feature, however, is not a magic bullet. The tool transparently analyzes the encryption type and will clearly state if bypassing is impossible—such as with modern AES-256 encryption.
QPDF is a robust library and command-line program that inspects and transforms PDF files. It is widely considered the "gold standard" for structural PDF manipulation.
