Aspose PDF and Iron PDF are widely used .NET libraries for PDF creation and modification among C# developers. Both libraries offer NuGet packages for easy installation and integration.

If you're wondering whether Aspose PDF converts HTML to PDF, the answer is yes, but with a limited capacity. Iron PDF, on the other hand, has a more sophisticated technology for PDF rendering, which uses a fully embedded web browser. This advanced technology allows for a much closer representation of HTML when rendered into a PDF document.
Another difference between these two programs is their licensing models. If you're trying to determine which application is more suitable for your IT needs, we recommend investigating your own use case and take a look at the licensing pages for both programs.
One of Iron PDF’s strengths is its comprehensive documentation for code examples. By browsing to IronPDF.com and clicking on "Code Examples," you will find 20 or 30 specific code examples that many developers find helpful when working with PDFs in .NET.
The core benefits of using Iron PDF include excellent HTML to PDF rendering, printing PDFs, and a usable PDF generation API, which is popular with the end user. Aspose PDF’s HTML to PDF render options are relatively limited using a Java-based embedded browser, which has then been ported to the .NET framework. Iron PDF uses native browsing technology developed in CnC++ to give a full document render and provide PDFs similar to those you might be able to print off from your own web browser, such as Chrome or Firefox.
