Frequently asked questions
What is the best Java PDF library?
There is no single best Java PDF library; the right choice depends on what you need to do. Apache PDFBox is a good free option for PDF creation and text extraction, iText is strongest for high-volume PDF generation, JPedal is built for viewing, rendering, conversion, and processing diverse or malformed PDFs, and the Adobe PDF Library offers Adobe-certified rendering fidelity. Match the library to your primary task, licensing constraints, and support needs.
Which Java PDF libraries are free and open source?
Apache PDFBox and ICEpdf are both free and open source under the Apache 2.0 license, which allows use in closed-source commercial applications at no cost. iText is dual-licensed under AGPL or a paid commercial license, while JPedal and the Adobe PDF Library are commercial only.
Is there a pure Java PDF library with no native dependencies?
Yes. Apache PDFBox, iText, JPedal, and ICEpdf are all written in pure Java and deploy anywhere a JVM runs, with no platform-specific binaries. The Adobe PDF Library is the main exception, as it wraps a native C or C++ engine and requires platform-specific binaries.
Which Java PDF library is best for viewing and rendering PDFs?
JPedal is purpose-built for PDF viewing and rendering and ships with a customisable Swing viewer, and it handles malformed and edge-case documents reliably. ICEpdf offers basic viewing on a smaller budget. Apache PDFBox and iText do not include a viewer component.
How much does a commercial Java PDF library cost?
Commercial pricing varies by vendor and deployment. iText typically ranges from around 3,000 to 20,000 US dollars or more, JPedal from around 1,000 to 10,000 US dollars, and the Adobe PDF Library from around 10,000 to 50,000 US dollars or more. Apache PDFBox and ICEpdf are free.
What is the difference between iText and Apache PDFBox?
iText specialises in high-volume PDF creation and manipulation and offers commercial support, but uses AGPL licensing unless you buy a commercial license. Apache PDFBox is free under Apache 2.0 and handles creation, extraction, and basic manipulation, but has no built-in viewer and relies on community support. Neither includes a full rendering viewer.
