Portable Document Format (.pdf)
The Portable Document Format (PDF) is a file extension created by Adobe Systems in 1993 to facilitate document exchange across different systems. PDFs preserve the formatting of source documents, making them ideal for sharing text, images, and graphics in a consistent manner. Commonly used for forms, manuals, e-books, and reports, PDF files are platform-independent, ensuring the content appears the same on various devices and operating systems. This versatility has solidified its status as a standard in digital documentation, enhancing both compatibility and security in file sharing.
