Iron PDF is a powerful software for ASPX developers offering advanced conversion capabilities of HTML and ASPX files to PDF for Microsoft.NET web, desktop, and console applications. It comes with a tutorial and code example to provide seamless ASPX to PDF functionality.

Once I installed the IronPDF library NuGet within Visual Studio, I was able to use its AspxToPdf static class in the ASPX code-behind Page_Load event to convert all of the HTML into a visually identical PDF file. This process allowed me to use ASP.NET print to create PDF documents from existing WebForms quickly.
Furthermore, I could generate PDFs in ASP by rendering HTML strings, files, or URLs into PDFs and serve them as downloads or archives. These PDF files could be displayed to the end user in-browser or as a file download with any specified format. Additionally, I had the option to specify display choices, including virtual paper size, margins, html headers and footers with data-merging & image render quality.
This ASP to PDF technology for .NET is demonstrated in the tutorial, which illustrates how to create a PDF with a limited amount of C# or VB.NET code. Moreover, the tutorial shows how this ASP.NET PDF file generation technology can be used to annotate, edit merge, and split PDF documents in real-time with C# or VB code.
Overall, this is a robust .NET PDF file library with conversion capabilities for both .NET to PDF and PDF to .NET. The accompanying articles provided me with additional valuable insights. The tutorial made it easy to understand the C# library used to convert ASPX files to PDF with the IronPDF C# VB .NET PDF generator application. If you're looking for an efficient and customizable tool for PDF conversion, this is certainly worth considering.
