"PDF". It is a cross-operating system
platform file format. Text, fonts,

plate-making output, and hypertext links
and audio can also be included and video
and other electronic information.
PNG, which stands for Portable Network
Graphics, is a popular raster image
format used for storing and transmitting
images. PNG is a versatile and widely
used format for storing and displaying
images, particularly when image quality
and transparency are important
considerations.
