Versions:
miPDFsign Community is the free, open-source edition of miPDFsign, published by Wolfgang Mitterbucher and licensed under AGPL-3.0. It is a .NET 8 WPF application designed for use with signature tablets, and it falls into the document signing and PDF software category. Its purpose is to capture handwritten signatures directly on a tablet together with biometric pressure data and to embed those signatures into PDF documents as PAdES signatures. PAdES support covers the Baseline B, T, LT, and LTA profiles, which makes the software suitable for use cases ranging from simple electronic signing of documents to scenarios requiring long-term signature validation. In addition, qualified electronic signatures (QES) are supported through integration with ID Austria, enabling legally recognized signing workflows in the Austrian context. The application relies on the iText PDF engine for its PDF processing and signature embedding functionality. Typical use cases include signing contracts, forms, and other documents directly on a signature tablet while preserving the biometric characteristics of the handwritten signature as part of the signed PDF. The current version of miPDFsign Community is 1.0.1, and two versions of the software have been released in total, indicating an early but actively maintained release history. Alongside the Community edition, a commercial edition of miPDFsign is available on request, offering additional features beyond those provided in the free AGPL release. Organizations and individuals who require an open, license-transparent solution for biometric tablet signatures can use the Community edition at no cost, while those with extended requirements can turn to the commercial offering from the same publisher. Overall, miPDFsign Community combines handwritten signature capture, biometric data recording, PAdES-compliant PDF signing, and optional qualified signatures via ID Austria in a single Windows desktop application built on modern .NET 8 technology.
