Highlights

• Provides content-preserving transformations on PDF files, including linearization (web-optimization) and encryption
• Supports converting PDF files with object streams to files with no compressed objects, or generating object streams for files that don't have them
• Includes the ability to merge and split PDF files by copying objects from one file to another and manipulating the list of pages
• Allows for the creation of PDF files from scratch, where the user supplies the content and the QPDF library handles the syntactical representation of the objects, cross-reference tables, object streams, encryption, and linearization
