What Is a PDF File?

PDF stands for Portable Document Format. A PDF file is a type of document that looks the same on every device.

It does not matter if you open it on a phone, tablet, or computer—the layout stays the same. PDF was created so that documents can be shared easily without changing their design.

Who Created PDF and Why?

PDF was created by a company called Adobe.

Before PDF, documents looked different on different computers. Fonts, pages, and images could move or break, making documents hard to share.

PDF solved this problem by locking the design of the document, so it appears the same on all devices.
