What is a PNG File?
PNG (Portable Network Graphics) is a raster graphics file format that was created as an improved, non-patented replacement for GIF (Graphics Interchange Format). Developed in the mid-1990s, PNG has become one of the most popular image formats on the internet and is universally supported across all platforms and devices.
PNG uses lossless compression, which means that no image quality is lost when the file is saved or compressed. This makes it perfect for images where clarity and precision are important, such as logos, diagrams, screenshots, and graphics with text.
