WHAT'S THE MEANING?
PDF stands for Portable Document Format which is an electronic file format used to present and exchange documents. The PDF was first pioneered by Adobe and is now an open standard maintained by the International Organization for Standardization or ISO. PDFs can contain links and buttons, form fields, audio, video, and more.
DID YOU KNOW?
Did you know that Adobe developed the PDF file format to make their office paperless? It was founder John Warnock's idea to develop a file format that any operating system can read. This internal project aimed to make file sharing easier for Adobe employees. Later on, the company introduced their innovation in San Jose, California in 1991 where they initially named called it as 'IPS' or 'Interchange PostScript.' The following year, they officially introduced the PDF format at the Comdex Fall. In 1993, Adobe released its own PDF file reader, Acrobat.
Now, there are numerous PDF reader apps available for different operating systems such as Mac, Windows, iOS, and Android. PDF is also one of the most used file formats for professional and recreational use. There are hundreds of websites where you can download free PDF books. Contracts, agreements, and other important business documents now come in this format as it is easier to access. You can even edit documents on-the-go using different PDF editor apps. With the accessibility and convenience the PDF file format offers, as well as the development of new technology, it wouldn't be long until Warnock's dream of a paperless office branches out to the whole world.
