What Is a PDF File?
PDF (Portable Document Format) was created by Adobe in 1993 to present documents consistently across all platforms and devices. A PDF preserves the exact layout, fonts, images, and formatting of the original document regardless of the operating system, software, or device used to view it. PDF files can contain text, vector graphics, embedded images, hyperlinks, interactive forms, digital signatures, and even embedded video — making them the universal standard for document exchange.
