PyPDF2

PyPDF2 ist eine Pure-Python-Bibliothek zum Transformieren, Sichern und Extrahieren von Daten aus PDF-Dokumenten. Sie bietet eine umfassende Suite von Tools, um Seitenlayouts zu modifizieren, Dokumentensicherheit zu verwalten und eingebettete Metadaten abzurufen, ohne auf externe C-Bibliotheken angewiesen zu sein.

Das Toolkit ermöglicht Dokumenten-Assembly durch das Zusammenführen mehrerer Dateien und das Aufteilen von Dokumenten in kleinere Teile. Es unterstützt zudem seitenbasierte Transformationen, einschließlich der Möglichkeit, Seiten zu drehen und sichtbare Crop-Bereiche anzupassen.

Die Bibliothek enthält Funktionen für Sicherheitsmanagement via passwortbasierter Verschlüsselung und Entschlüsselung. Zusätzlich bietet sie Utilities für die Extraktion von geschriebenem Text und administrativen Eigenschaften aus PDF-Dateien.

Features

  • PDF Parsers - Provides a pure-Python parser to convert raw PDF binary data into structured Python objects.
  • Password-Based Encryption - Implements standard PDF security algorithms for encrypting and decrypting document streams using passwords.
