The PDF image file format is developed by Adobe, but, unlike other Adobe formats, does not require any company-specific software (although Acrobat Reader is the corresponding standard). The PDF format has established itself as a reliable exchange format and can be viewed without paid editing software – on any device, any operating system, and any web browser. The format is particularly popular to showcase print files.
With the Adobe range of programs, which are subject to a fee, PDFs can be processed in a versatile and flexible way. The foundation of this picture format particularly shows its strength for vector graphics, but also maps pixel graphics. Even in the free version, PDFs can be expanded on with additional features such as notes, comments, or file attachments. Appropriate security settings can be used to prevent editing by third parties.
