IronPdf

IronPDF is a developer-focused PDF library for .NET that creates, reads, and edits PDF documents in application code. It is commonly used by software teams building reporting, invoicing, form output, or document workflows in C# and ASP.NET environments.

A core capability is rendering HTML, CSS, and web content to PDF, which makes it useful when teams already generate document layouts with web technologies. It also supports common programmatic tasks such as merging PDFs, adding headers and footers, extracting text, and applying security settings. Its distinguishing trait is its emphasis on HTML-to-PDF generation within the .NET ecosystem rather than end-user desktop document editing.
