PDF (abbreviation for
Portable Document Format) is a file format developed by the
Adobe company. It can be used for storage of documents independently on software and hardware where the document originated. The
PDF file type may contain both text and images while the format provides identical viewing of such document on any device. The
PDF documents can be cretaed in commercial software
Acrobat by
Adobe, but also in other programs (usually only as export to
PDF).
There are many free PDF viewers available for various platforms, but the best known is the viewer
Adobe Reader. Some active type content (for example interactive forms, 3D graphics, videos, audio, etc.) may not be supperted by many PDF viewers. The PDF format files have the
.pdf suffix. PDF is an open standard that is easily portable (viewing is independent on used software and hardware) and therefore very popular.
