PNG

This term refers to a specific technical standard for digital imagery. In professional design and web development, it is distinguished from the JPEG format by its ability to handle alpha channels, which allow for varying levels of transparency. This makes it the standard choice for logos, icons, and graphics that must overlay different background colors without a solid white box around them.

As a technical acronym, it is typically treated as a countable noun when referring to individual files (e.g., "three pngs"). While it is an abbreviation for Portable Network Graphics, it is almost exclusively used as a standalone noun in modern digital contexts.
