In der heutigen CAD- und Dokumentenverwaltung ist die effiziente Speicherung und Übertragung von Bilddaten entscheidend. AVIF, als modernes Bildformat, bietet exzellente Kompression bei hoher Qualität, ist jedoch nicht immer kompatibel mit älteren Systemen oder spezialisierter Hardware, die oft noch in der DACH-Region im Einsatz ist. Hier kommt G3 ins Spiel: Dieses ältere, aber äußerst robuste Fax-Format ist der De-facto-Standard für binäre Bildübertragung in vielen Geschäftsprozessen, insbesondere wenn es um die langfristige Archivierung oder die Kompatibilität mit etablierten Dokumentenmanagementsystemen geht. Unser Konverter schlägt die Brücke zwischen diesen Welten. Er ermöglicht Ihnen, die Vorteile der AVIF-Kompression zu nutzen und gleichzeitig die breite Akzeptanz und Verlässlichkeit des G3-Formats für Ihre technischen und geschäftlichen Anforderungen zu gewährleisten. So bleiben Ihre Daten flexibel und zugänglich, ohne Kompromisse bei der Systemintegration eingehen zu müssen.

  • Archivierung technischer Zeichnungen
  • Kompatibilität mit älteren Scannern/Plottern
  • Austausch von Bauplänen via Fax-Server

Die Umwandlung zu G3 ist in der DACH-Region besonders relevant für die Einhaltung von Archivierungsvorschriften und die Interoperabilität mit spezialisierten CAD/CAE-Systemen, die oft auf binäre TIFF-G3-Standards setzen.

About AVIF to G3 (FAX) Conversion

AVIF (introduced 2019) and G3 are both image formats, but they differ in important ways. AVIF is the newest image format based on AV1 video codec, delivering exceptional compression — up to 50% smaller than JPEG at the same quality. G3 is a widely used file format.
