Today, Red Software publishes RAD PDF 3.49, its web-based GUI / WebControl for PDF viewing, PDF editing, PDF form filling, PDF redacting, PDF signing and more! RAD PDF works with virtually EVERY .NET Core or .NET Framework web application type including Angular, Blazor, Razor, React, MVC, WebForms, and more, making PDF-webapp integration easier than ever.

Primarily, this release includes integration improvements like a new option to set the HttpHandlerPath. This allows for requests to be sent to a custom path for HTTP requests (instead of the default "RadPdf.axd").

A critical update, version 3.49 also includes a fix for a buffer overflow vulnerability in the ASCII85 decoder being used. We highly recommend all customers update to this latest version as soon as possible/

Along with minor bug fixes, this release continues to improve the most widely compatible PDF editing solution for ASP.NET. This version is compatible with Windows Server 2025 and SQL Server 2025.

This update is available free of charge to all customers with an active Maintenance Plan
