DescriptionPortable Network Graphics, or .png, is a raster graphics file format. Simply put, it's a digital image format. PNG files are popular online because they use lossless data compression and support transparent backgrounds.
Technical detailsLet's look at the technical details of the .png format: PNG compression is lossless, meaning that all the image data is kept during compression. This is different from JPEG, which uses lossy compression and loses some image information to make smaller files. PNG images can range from basic black-and-white (1-bit) to very detailed images with 48 bits of color. They also support 16-bit grayscale images. A key feature of PNG is its support for alpha channel transparency. This lets you create images with varying degrees of transparency, from completely opaque to completely transparent. This is very useful for web graphics. PNG supports a full range of colors (truecolor), allowing for up to 16 million colors. It also supports indexed-color images, which use a palette of up to 256 colors. In short, PNG files are widely used because of their efficient compression, support for many different color palettes, and the ability to handle various transparency levels. These features make them perfect for many web applications.
