Java applications frequently need to produce PDF files – invoices, reports, contracts, shipping labels. The library you pick determines how much code you write, what web standards you can use, and what license restrictions apply. The Java ecosystem has several approaches, from low-level programmatic construction to browser-based HTML to PDF conversion. Below are code examples, feature tables, and recommendations for the most popular Java PDF libraries – from programmatic PDF builders to HTML to PDF converters.

Most Java HTML to PDF libraries rely on browser engines to render content. But if you need full control over layout, fonts, positioning, and structure – especially for invoices, reports, or certificates – Apache PDFBox offers a code-driven alternative. Rather than converting web pages, PDFBox lets you programmatically construct PDF documents from scratch using Java. This guide covers PDFBox's low-level API for creating formatted PDFs – you skip browser dependencies entirely and control exactly how your documents are styled, structured, and generated.

Programmatic PDF generation is a common requirement for Java applications that produce invoices, reports, or contracts. OpenPDF, a lightweight and open-source PDF library derived from iText, provides a free solution for creating these documents in Java. In this step-by-step guide, we'll build a PDF invoice generator using OpenPDF as a practical example you can adapt to your own projects.
