Change log: Updates, milestones, roadmap

IronPDF Roadmap

We have made IronPDF the leading¹ .NET HTML to PDF product by prioritizing compatibility, usability and results. Now, our mission is to maintain that hard-earned reputation by continually updating IronPDF with the latest HTML, CSS and JS technology shifts; and the cutting edge versions of Chrome.

Our software is developed for engineers, by engineers, so we understand the value in rigorous testing, support, and transparent one-time licensing.

We pride ourselves on listening to our community and demonstrate this by prioritizing feature requests based on what you, our customers, ask for.

Long term we plan to diversify IronPDF by offering it in multiple programming languages.

^{¹Based on an independent audit of our product in August 2022.}
