OpenPDF 3.0.0

OpenPDF 3.0.0

  • OpenPDF 3.0.0 uses the new package name org.openpdf. The old com.lowagie is now removed from OpenPDF 3.0. This means that source code using OpenPDF must be migrated to use import statements using org.openpdf.* package.

  • PDF 2.0 support in OpenPDF – This is a breaking API change:
    All version-related methods now use String instead of char as method parameters. See PdfVersion.java and PdfWriter.java. The default version is now PDF 2.0.

    About PDF 2.0:
    PDF 2.0 is the latest official version of the Portable Document Format, standardized as ISO 32000-2:2020.
    It was first published by the International Organization for Standardization (ISO) in July 2017, with a revised edition in December 2020.
    PDF 2.0 introduces improved color management, tagged PDF enhancements, advanced encryption options, and clarifies many ambiguous parts of the PDF 1.x specifications.

  • Added HtmlToPdfBatchUtils and PdfBatchUtils, new batch utilities built on Java 21 virtual threads. These APIs improve throughput for HTML→PDF rendering and common PDF tasks such as merge, split, watermark, and encrypt.

2.2.0

OpenPDF 2.2.0 Released!

We’re excited to announce the release of OpenPDF 2.2.0, a new milestone in our ongoing mission to build a modern, fully open-source PDF library for Java.

What's New

openpdf-renderer Module Added (#1357)

We’ve added a brand new module: openpdf-renderer.

This module integrates the openpdf-renderer engine into OpenPDF, enabling:

  • High-quality PDF rendering to images
  • Fast page previews and thumbnails
  • Support for converting PDF pages to BufferedImage for use in Java applications

It’s perfect for developers who need visual previews of PDFs in desktop or server-side applications.

OpenPDF 2.1.0 - Modernization and New Features

We are excited to announce the release of OpenPDF 2.1.0, which marks a major step forward for the project.

  • Java 21 required: OpenPDF 2.1.0 now targets Java 21 LTS and benefits from its modern features and performance improvements. Java 21 was released in 2023.

  • New Kotlin module: Build PDFs more easily using idiomatic Kotlin APIs and a DSL-inspired builder interface.

  • Added openpdf-html module: A maintained fork of Flying Saucer for converting HTML to PDF, now part of the OpenPDF project. The goal is to improve HTML5 and modern CSS support.

  • Deprecated HtmlParser: We encourage migrating to openpdf-html for improved HTML rendering.

  • Updated dependencies.
