PDF (Portable Document Format)
PDF is a file format developed by Adobe Systems in 1993, designed to present documents that include text, images, and graphics in a format independent of the software, hardware, and operating system used to create or display them.
PDF stands for Portable Document Format and is now a global standard for sharing digital documents.
In the context of digital marketing, PDFs are often used to share guides, reports, brochures and other types of downloadable content.
