What is meant by PDF file?
A PDF file (Portable Document Format) is a file format developed by Adobe Systems that allows documents to be displayed consistently across different platforms. PDFs preserve the original layout, fonts, images, and graphics of the document, regardless of the device or operating system used. This makes the format ideal for creating and exchanging documents that need to be viewed consistently across various devices and operating systems.
