Pdfsam
pdfsam is a PDF manipulation software and desktop application designed for splitting, merging, rotating, and extracting pages from PDF documents. It functions as a PDF editor, converter, and security tool, providing capabilities to modify document structures and manage file formats.
The project distinguishes itself through specialized processing capabilities, including an OCR document processor for extracting editable text from scanned images and PDF interleaving to alternate pages from multiple files. It also provides a security suite for encrypting documents, managing access permissions, and applying digital signatures.
The software covers a broad range of document optimization and editing tasks, such as page organization, direct content editing, fillable form creation, and PDF compression. It also includes tools for page rotation, cropping, grayscale conversion, and the insertion of annotations and hyperlinks.
The application is built as a Java-based desktop runtime.
