What is PNG?
PNG stands for Portable Network Graphics, and is a common format for saving image files. The PNG format is often used for images on the web or when making a website because it offers two main benefits. First of all, PNG files can have a transparent background, meaning no distracting white box around the image. Second, similar to a .GIF file, a PNG file is lossless, meaning it maintains its image quality even after being compressed.
What is a PNG file used for?
PNG files are particularly useful for grayscale images and images with a transparent background.
The difference between PNG and JPG
PNG files maintain a high level of image quality, but are generally large in size. Alternatively, an image in JPEG or JPG format is compressed or “lossy,” which means that it has lost some of its original quality. PNG files also support a transparent background around an object, while JPGs will have a box-shape.

How to choose whether to use a PNG or a JPG File
PNG files offer maximum quality and the benefit of a transparent background. Their large size, however, can contribute to slower loading times on the web. JPG files are good to use when quality is less important and if fast loading time and page speed is a top priority.
