What is it?
PDF (Переносимый формат документов) был создан Adobe в 1993 году и стал открытым стандартом в 2008 году. Он захватывает документы - включая текст, шрифты, векторную графику и изображения - в фиксированном макете, который выглядит идентично на любом устройстве или операционной системе.
PDF-файлы могут содержать интерактивные элементы, такие как формы, гиперссылки и цифровые подписи. Они поддерживают шифрование и защиту паролем, что делает их стандартом для юридических, финансовых и официальных документов по всему миру.
