Description Le format PDF (Portable Document Format) est un format de fichier vectoriel évolutif conçu par Adobe Systems en 1993. Le format PDF a été développé pour créer des documents indépendants de la plate-forme pouvant être visualisés sur plusieurs périphériques et tailles d'écran. La représentation d'un fichier PDF est toujours indépendante du système d'exploitation, du logiciel et du matériel.
Détails techniques Le fichier PDF a une disposition fixe qui permet aux utilisateurs d'éviter les problèmes de polices manquantes, d'éléments mal placés, de graphiques déformés, etc. Les documents PDF sont toujours compatibles, quel que soit le logiciel utilisé pour créer et éditer votre PDF. En outre, il est possible d'empêcher l'impression d'un document PDF et de le protéger avec un mot de passe.
Développé par ISO
Version initiale Le 15 juin 1993
