PNG is the acronym for Portable Network Graphics, a file format designed for graphics like graphs, logos, and text. PNGs can also be saved as photographs. JPGs are often inferior in quality to PNGs. Since PNG files were not intended to reduce file size, they retain more image detail and color details. PNG files can be viewed and shared across a wide range of platforms and software programs, just like JPG files. The .png format is often associated with icons in web browsers file version of that icon.

Advantages of PNGs

Lossless Image Quality

With PNG, you have no loss of quality when you save, edit, and open the image repeatedly. JPG files, on the other hand, lose information every time they are edited or re-saved, further compressing them.

Transparency Features

Transparency is one of the biggest advantages of PNG files, making this file format ideal for icons, logos, and smaller graphics. PNG images often have a gray checkered background before you download them, indicating their transparency.

Disadvantages of PNGs

Larger File Size

A large part of the reason JPG images are used on the web is their friendly file size. POS printing uses a different type of compression to reduce the file size, but not as much as a JPG.

Photo or printing is not recommended

As PNGs have lossless image quality, they are best reserved for online images with a limited color palette. In this situation, JPGs and PDFs are more suitable than PNGs.
