jPDF Tweak

jPDF Tweak is a Java-based utility designed for manipulating and editing existing PDF documents. It provides a comprehensive interface to perform various document operations such as combining multiple files, splitting pages, rotating documents, and changing metadata properties. Users can also apply cryptographic protections, set user permissions, and attach additional files to the document structure.

The application operates primarily through a graphical user interface where users select specific processing tasks via dedicated tabs. It functions as a standalone utility on Linux platforms and requires a Java runtime environment to execute. While it handles complex document adjustments, it is not structured to function as a traditional page-layout editor for modifying existing text or vector graphics within a page.
