Release pdfHTML 6.1.0

Release date: Feb 14th, 2025

pdfHTML is an iText Core add-on for Java and .NET to create PDF from HTML/XML (and associated CSS).

This release focuses on extending the existing support for GraalVM Native Image to pdfHTML, and major improvements to CSS. In addition, pdfHTML takes advantage of Core enhancements such as table performance, SVG, font handling, layout and PDF/UA. See the iText Core release notes for full details, along with the included showcase PDF to see what pdfHTML can do!

GraalVM Native Image

Our built-in support for GraalVM Native Image compilation now includes pdfHTML. This means you can potentially build a complete template conversion executable to run anywhere, using only the Core and pdfHTML modules you need, while benefiting from the performance gains that GraalVM brings with its JIT compilation process.

SVG and CSS Improvements

As mentioned above, pdfHTML hugely benefits from the extended SVG and CSS coverage in this release. In particular, the text-decoration, marker-mid, and stroke-dash-array additions, along with support for different CSS origins in SVG.

There are improvements to SVG Text, which also benefit pdfCalligraph. Along with that are numerous refinements and bugfixes to aid utilizing SVG and CSS for templating. One thing to call out is the improved Flex container usage with tables. Speaking of which…

Table and Forms Improvements

We’ve already mentioned the massive performance increase for tables in Core, and HTML template conversions with tables will take great advantage of this. Using pdfHTML for PDF/A and PDF/UA conformance will also see especially large performance increases, due to the tagged table optimizations.

In addition, the conversion of HTML forms for PDF/UA conformance is improved.
