First we will begin with something simple. Improving ourvocabulary and a quick reference guide to compare file size andquality based on format.
GIF - Graphics Interchange Format
The author of the file format GIF pronounces the acronym with asoft G like giraffe, not with a hard G like gift
PNG - Portable Network Graphics
The PNG specification (or the Scope section of the newerISO/IEC/W3C version) states that PNG is pronounced in English as "ping" not "pinj" or "pee en gee". However, for non-Englishspeakers, the three-letter pronunciation is accepted.
