PNG files are a widely used graphics file format used in areas where high-quality images (often with transparency) are required while also retaining a small file size. They are one of the most common formats of file used for web and print mediums and are particularly useful for logos, icons, and other images where multi-level transparency is desired.

The format itself was created in the 1990's with the main aim of storing computer graphics in a high-quality format while minimizing the required storage space. The longer-term aim was to displace the GIF file format and make PNG the number one format for non-lossy, high-quality image formats on the then-burgeoning world wide web.

One of the selling points of the PNG format is its support for multiple levels of transparency, making it superior to the GIF format, which can only handle a single level of transparency. Also, like GIFs, the PNG format supports palletizing image colors down to 256 or 16 colors to help reduce the file size of the PNG.

Extension	ICO
Full Name	Icon
Type	Image
Mime Type	image/x-icon
Format	Binary

An ICO file is a bitmap graphics format first introduced as part of the Windows operating system as a means of assigning a user-friendly visual indicator for applications that run on the operating system.

Multiple images can be stored within a single ICO file; these images can be of varying sizes and color depths, with the operating system choosing the most appropriate size when rendering an icon for a specific task.

As the ICO format has been around for many years and is still used today not only by Windows but also by other platforms, it is well supported with many 2D graphics applications able to export to the ICO file format.
