PDF: Revolutionizing Document Sharing
Published on:
Introduction
The Portable Document Format (PDF) is a versatile file format developed by Adobe Systems in 1993. It was designed to present documents consistently across various devices and platforms, ensuring that the content remains unchanged regardless of where it's viewed.
History of PDF
In 1991, Adobe co-founder John Warnock initiated the "Camelot Project," aiming to create a universal format for document exchange. This project led to the development of PDF, which Adobe officially launched in 1993. Initially, PDF faced competition from other formats, but its ability to preserve document fidelity across platforms soon made it the preferred choice for digital documents. In 2008, PDF was standardized as ISO 32000-1, further solidifying its position as a global standard for document exchange.
