    PDF Library

    Big Faceless Organization

    Seamless PDF creation and editing for developers made easy.
    Introducing a compact and efficient PDF library designed for the creation, editing, display, and printing of Acrobat PDF documents. This PDF API is not only lightweight but also swift, making it simple to integrate into various projects while being entirely developed in Java. The design of the API eliminates the necessity of understanding the intricate PDF specifications for PDF creation. We strive to obscure the complicated aspects while still providing you with near-total control over the PDF content. Wherever feasible, we leverage standard Java classes; for instance, pages are organized in a java.util.List, allowing for effortless manipulation, such as transferring pages between documents. This leads to an API that is both smaller and more user-friendly. Additionally, the Viewer Extension facilitates the parsing of PDFs and their conversion into bitmap formats for display, as well as saving them as bitmap images (like TIFF) or for printing purposes. While Java 5 claims to support direct PDF printing, the results can often be subpar, and its support for features such as annotations and encrypted documents is frequently lacking. Our PDF library addresses these shortcomings, ensuring reliable and high-quality results across all PDF files. Ultimately, this makes it an essential tool for developers looking to work with PDF documents seamlessly.
