How Can I Seamlessly Convert HTML to PDF Using iText 7 and Avoid HTMLWorker Deprecation?

Converting HTML to PDF with iText

Deprecation of HTMLWorker

HTMLWorker is deprecated and no longer recommended for converting HTML to PDF. Its successor, XML Worker, provides more robust and comprehensive functionality.

Styling Issues with XML Worker

XML Worker supports CSS, but not all styles are respected. In particular, float positioning is not implemented.

Steps to Convert HTML to PDF Seamlessly

Upgrade to iText 7 and pdfHTML 2: This provides a simplified and feature-rich solution for HTML to PDF conversion.
Use HtmlConverter: HtmlConverter.convertToPdf() performs the conversion seamlessly and accurately respects CSS.

Additional Notes

License Considerations: iText 7 is released under the AGPL license, which allows free use in open source projects but requires a commercial license for closed source applications. PdfHTML is now open source and released under the GPLv2 license.
Legacy System Maintenance: Migrating to iText 7 can simplify code and enhance error handling.
Early Adoption: Developers who have recently started using iText should consider starting fresh with iText 7 to take advantage of its improved functionality.

Top 5 Java Features: Examples and ExplanationsMay 12, 2025 am 12:09 AM

The five major features of Java are polymorphism, Lambda expressions, StreamsAPI, generics and exception handling. 1. Polymorphism allows objects of different classes to be used as objects of common base classes. 2. Lambda expressions make the code more concise, especially suitable for handling collections and streams. 3.StreamsAPI efficiently processes large data sets and supports declarative operations. 4. Generics provide type safety and reusability, and type errors are caught during compilation. 5. Exception handling helps handle errors elegantly and write reliable software.
