What does the acronym "PNG" stand for?

The acronym "PNG" stands for Portable Network Graphics. This file format was developed to provide a better alternative to the GIF format, especially with its support for a wider range of colors and transparency. PNG files are particularly valued for their lossless compression, meaning that image quality is preserved even when file size is reduced. This makes PNG a popular choice for web graphics, particularly those that require clear and detailed images, such as logos and illustrations.

The use of the word "Portable" in the name denotes its compatibility across various platforms and devices, enhancing its utility in digital applications. The other options presented do not accurately refer to any recognized graphics format, which underlines the significance of understanding standard file formats in graphic design.
