JPG can often provide better compression than PNG but significant artifacts could be introduced in images with text or around high contrast areas.
PNG files are an evolutionary response to the GIF format, since the latter had some drawbacks, such as the need for a patent license and its limited color gamut of 256, which did not adapt to the constant improvement of the resolution of images. computer screens. The PNG file format has some important advantages, including that it can be compressed without losing quality. Also, PNG files support up to 16 million colors.
