| Introduction | Portable Network Graphics is a lossless compressed bitmap graphics format. It was designed to replace GIF and TIFF while adding features not available in GIF. PNG uses lossless data compression derived from LZ77 and is commonly used in Java programs, web pages, and S60 programs because it offers a high compression ratio and small file size. | ICO is the Windows icon file format. An icon file can store a single image or icons with multiple sizes and color palettes. Icons have standard sizes and attributes and are usually small. Each icon contains multiple images with the same visual content, and each image can use a different size and color depth. In this sense, an icon is a set of similar images in different formats. |
