Open-source PDF software

Open-source PDF software refers to programs that allow users to create, edit, and manage PDF files, with the source code freely available to the public. This means anyone can use, modify, and distribute the software without cost. Such tools often include features like merging documents, converting files to and from PDF format, and adding annotations. Popular open-source PDF software includes applications like PDFsam and Scribus. By being open-source, these programs encourage collaboration and continuous improvement, providing users with flexible and often powerful options for handling PDF documents without the financial burden of proprietary software.
