RAD PDF is a .NET component for ASP.NET and ASP.NET Core applications that adds a browser-based PDF viewer, editor, and form filler to a website without requiring Adobe Acrobat, Flash, or ActiveX plugins. It runs entirely on the developer's own server and integrates directly with ASP.NET Web Forms, MVC, Razor, Blazor, and Web API projects. Capabilities include client-side PDF editing and annotation, an interactive PDF form designer, PDF security controls, and an extensive developer API for customizing document workflows.
