Beschreibung Das Portable Document Format (PDF) ist ein skalierbares, vektorbasiertes Dateiformat, das im Jahre 1993 von Adobe Systems entwickelt wurde. PDF wurde entwickelt, um plattformunabhängige Dokumente zu erstellen, die auf mehreren Geräten und Bildschirmgrößen angezeigt werden können. Die Darstellung einer PDF-Datei ist immer unabhängig von Operationssystem, Software und Hardware.
Technische Daten Die PDF-Datei verfügt über ein festes Layout, das es Benutzern ermöglicht, Probleme mit fehlenden Schriften, falsch platzierten Elementen, verzerrten Grafiken usw. zu vermeiden. PDF-Dokumente sind immer miteinander kompatibel, unabhängig von der Software, mit der Sie PDF erstellen und bearbeiten. Außerdem ist es möglich, das Drucken eines PDF-Dokuments zu verhindern und es mit einem Passwort zu schützen.
Entwickelt von ISO
