UWP PDF library
Nutrient UWP SDK is an SDK for viewing, annotating, editing, and signing PDFs. It offers developers a powerful API for quickly adding PDF functionality to any UWP application.
Nutrient UWP SDK (formerly PSPDFKit for Windows) has been deprecated, in line with Microsoft’s decision to gradually phase out UWP by limiting updates to bug fixes and security patches. All Nutrient UWP licenses will continue to work and be supported until 1 December 2026, or until your license expires, whichever occurs later. Interested in transitioning to another Nutrient product? Contact us and we’ll be happy to help.
