PDF document
The Portable Document Format (PDF) is a universal file format designed for presenting documents independently of application software, hardware, and operating systems, ensuring consistent display across platforms.
What is PDF document?
PDF was developed by Adobe Systems in the 1990s to facilitate reliable document exchange. It encapsulates a complete description of a fixed-layout document, including text, fonts, vector graphics, and raster images. It became an open standard (ISO 32000-1) in 2008. PDFs are widely used for official documents, reports, and digital publications due to their integrity, security features, and consistent rendering.
