What are PNG and JPG formats?
PNG format
The Portable Network Graphics format or better known as PNG is the most used for web design. It features its transparent backgrounds, which is why it is used for logo design.
there two types of PNG, PNG-8 and PNG-24. The first is characterized by the use of a limited color palette of 256 colors and can be saved in small formats. Unlike PNG-24 which has an unlimited color palette but its dimensions are much larger.
JPG format
Joint Photographic Experts Group or JPG This is the most used image format. Most of the images use this format due to its virtually unlimited color palette. Also, image quality may vary with file compression.
The disadvantage of JPG is that every time an image is saved it loses quality. It is the ideal format for photographs or any image with many colors. Unlike PNG, this format does not support transparency.
