open-source PDF libraries

Open-source PDF libraries are software tools that developers can freely use, modify, and share to create, read, or edit PDF files—documents like reports or forms. They are made available to the public, fostering collaboration and innovation. These libraries provide functionalities such as extracting text, adding signatures, or filling out forms, enabling customization without licensing costs. Popular examples include libraries like PDF.js and Apache PDFBox. They support a wide range of applications, from simple viewing to complex document management, helping developers integrate PDF capabilities into their software efficiently.
