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 colours down to 256 or 16 colours to help reduce the file size of the PNG.

A ZIP file is a compressed file container format that has been around for many years and has become a universal standard for compressing multiple files into a single package. Along with compressing individual files, ZIP files can also compress entire directory structures.
The compression algorithm of the ZIP format enables highly efficient compression of most file types, whether they be text, music, or images. ZIP files are a great way to group together and compress multiple files for easy storage and distribution.
As ZIP files have become a standard format for file compression, most operating systems and platforms are capable of creating and opening ZIP files without any additional software.
