PDF (Portable Document Format) is the most universally used document format in the world. Understanding what PDF is helps you use it more effectively.
What PDF stands for
PDF = Portable Document Format. Created by Adobe in 1993, now an open international standard (ISO 32000).
Why PDF is universal
PDF files look identical on every device, OS and printer. Fonts, images and layout are all embedded — nothing changes when you share it.
Types of PDF
Searchable PDF (text can be selected/copied), Scanned PDF (image-only, text cannot be selected), Form PDF (fillable fields), Secured PDF (password protected).
