OpenPDF is an open-source Java library (LGPL/MPL licensed, forked from iText 4) for creating, editing, rendering, and encrypting PDF documents. It includes modules for generating PDFs from HTML, rendering PDFs as images, and Kotlin-friendly PDF creation.
Use cases
- generate pdf documents from java
- convert html to pdf
- encrypt pdf files programmatically
- edit or merge existing pdf documents
- render pdf pages as images
- create pdf tables and reports in java
- extract text from pdf files
When to choose
- you need a permissively licensed (LGPL/MPL) Java PDF library
- you want to generate PDFs from HTML in a JVM application
- you need to create, modify, or encrypt PDFs on the JVM
- you want PDF 2.0 (ISO 32000-2) support
- you prefer a community-maintained fork of iText 4
When to avoid
- you need a non-JVM language without JVM interop
- you require advanced commercial PDF features like digital signature workflows with vendor support
- you need a lightweight client-side browser PDF viewer
