The STP file format is a 3D format defined in 1994 and used to store 3D objects for use in Computer-aided design (CAD) applications. STP files are text-based formatted files containing one instance per line.

Although STP files are widely supported by most CAD applications the format does have its limitations, such as the necessity to read the complete file into memory in order to parse the contents and due to the text storage of information the files can be quite large.

The PNG graphics file format is a commonly used format for storing 2D images which can be highly compressed by the use a palette if the image has a sufficiently low number of colors (256 colors in general). The PNG file is then further compressed using the DEFLATE compression algorithm to ensure small file sizes that are fast to download.

PNG files are seen as the logical successor to the GIF image file format and was devised in the mid-1990's as a superior format to GIF. PNG files are generally used for company logos, icons and other non-photographic image content. Saving a digital photo in the PNG format will create a much larger file than an equivalent JPG image hence the PNG format being unsuitable for most digital photo content.
