Wolfgang Mitterbucher is an independent software publisher whose catalog, available through mitterbucher.com, focuses on PDF document processing solutions for Windows environments. The publisher's product range currently comprises two packages that address common workflows in document digitization, output management, and electronic signing. The first product, miPDFconvert, is a virtual PDF printer for Windows that converts any printable document into a PDF file and then hands the result directly to a configurable target application. This makes it suitable for organizations that need to route print output into downstream systems such as document management platforms, archiving solutions, or custom business applications without manual intervention, effectively turning the standard Windows print function into an integration point for automated document pipelines. The second product, miPDFsign Community, is the free AGPL-licensed edition of miPDFsign, a tablet-based signature application that captures handwritten signatures along with biometric data and embeds them into PDF documents as PAdES-compliant signatures. This addresses use cases in which legally relevant signatures must be collected on the spot, for example at service counters, during deliveries, in medical practices, or in field service scenarios, where customers or patients sign directly on a tablet and the signature is securely bound to the document. Because the Community edition is released under the AGPL open source license, it also appeals to developers, public institutions, and companies that value transparency and the ability to audit or adapt the software. Taken together, the publisher's offerings target businesses and organizations seeking lightweight, specialized tools for producing PDFs from any application and for replacing paper-based signing processes with standards-compliant digital alternatives on Windows and tablet devices.
