Iron PDF for ASP.NET allows users to generate PDF documents using HTML to PDF technology. It also enables PDF editing, content extraction, and PDF signing.
With IronPDF, developers can render Web Forms and MVC Views directly into PDFs, generating an identical PDF to the original web resource. In addition, developers can generate PDFs using HTML to PDF technology with the Chromium web browser engine under the hood. This automatically converts HTML strings, local webpages, or remote URLs into PDFs using only a single line of code.
Developers can generate a standard ASHX page, MVC View, or static HTML page, or even HTML as a string, and use Iron PDFs HTML to PDF conversion functions to render that HTML as a fully functional PDF, which may include forms and other advanced HTML and PDF features. Iron PDF supports HTML5 and CSS3, as well as JavaScript. Images, SVGs, and advanced CSS tricks are all supported.
Iron PDF can also be used to sign PDFs, edit existing PDFs, and extract content such as text and images from uploaded PDF documents. Developers don't need to install anything for Iron PDF to run. Using a headless web browser, Iron PDF can render full webpages, including JavaScript libraries and charting libraries, and render them into PDF documents.
There are some limitations to the amount of memory which may be used to load JavaScript libraries, but generally Iron PDF is fully JavaScript, CSS, and HTML5 compatible. Iron PDF is free for development use and can be used liberally on machines where Visual Studio is in use or developers are debugging and working with applications.
Iron PDF also offers commercial licensing for deployment when your ASP.NET website is deployed to a staging or live web server. To install, simply use NuGet by searching for the Ironpdf package. With its comprehensive features and ease of use, Iron PDF is a top choice for developers looking to work with PDF files.
