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.
