jPDF Tweak

What jPDF Tweak is
jPDF Tweak is a free Java Swing application for modifying PDF files on Windows and Linux. It can combine, split, rotate and reorder documents, add watermarks, encrypt files, apply signatures, and change PDF properties. For print preparation, it creates booklets with shuffle and N-up layouts. Editing controls cover bookmarks, page numbers, metadata, transitions, attachments and page sizes. Batch processing applies identical settings to multiple files, with variables in output filenames to help prevent overwriting. Signing uses a key and certificate imported into a Java KeyStore. The application requires Java 5 or higher. Windows and Linux binaries bundle native JMuPdf libraries for image export; the manual says matching libraries also support image and multipage TIFF output. An encrypted input requires its owner password for decryption. Combining files can drop page numbers, document information and forms. The maker describes documentation as incomplete, and version 1.1 binaries are listed.
