A PNG, or Portable Network Graphic, is a raster image file format that supports lossless data compression. PNG was created as a replacement for the GIF format, and it has become one of the most popular image formats on the web. PNG files can be used for both online and offline applications, and they are often used for images with large areas of solid color, such as logos and icons.
PNG files are important because they offer a number of advantages over other image formats. First, PNG files are lossless, which means that no data is lost when the file is compressed. This makes PNG files ideal for images that need to be preserved in their original quality, such as photographs and illustrations. Second, PNG files can be saved with transparency, which makes them ideal for use in web design and other applications where transparency is required. Third, PNG files are relatively small in size, making them easy to store and transfer.
