PNG (Portable Network Graphics) is a popular bitmap graphic file format used on the Internet and supports lossless compression technology and transparency. The Deflate compression algorithm, designed for PNG files, reduces the size of the saved image without losing the quality of the final image. PNG is equally readable by all types of modern browsers and graphic editors. This format is often used to store logos and icons thanks to its support for transparent backgrounds.
