Today, Red Software releases RAD PDF 6.0, the latest version of the ASP.NET web component & drop-in-place GUI for editing PDF files, filling PDF forms, redacting PDF content, signing PDF documents, and more on almost ANY device. RAD PDF supports everything from the latest versions of Chrome and mobile Safari to even Internet Explorer 6! RAD PDF runs on the .NET Framework (3.5 / 4.x) as well as .NET Core, 5, 6, 7, 8. 9, 10, and 11 using Blazor, Razor, MVC, WebForms, and more. Our nuget can be installed on Windows or Linux machines.

Version 6.0 features an vastly overhauled PDF rendering engine! This new, server-side rendering engine has the ability to render PDF files at high resolution more quickly and accurately. It also features multi-threaded processing and increased PDF compatibility.

This upgrade also adds WebP image format support. WebP images can be added to PDF files (or converted to PDF) just like other image formats supported by RAD PDF. (BMP, GIF, JPG, PNG, SVG, and TIFF are also supported.)

The ExportData() / ExportFormData() methods now have overloads allowing the Encoding for XFDF output to be specified.

And signed PDF files have increased compatibility with RAD PDF by no longer forcing annotations which are missing a name to have one added (thus invalidating the signature). RAD PDF now hashes attributes of those annotations so that they can be properly matched when saving to PDF.

This release fixes a number of important bugs, including potential security vulnerabilities.

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