PNG and JPEG Comparison

JPG or JPEG is Joint Photographic Experts Group (a team that developed the picture coding standard). It is a lossy compression of images which is comparatively smaller in size.

PNG is Portable Network Graphics. It is a lossless compression of an image which is much clearer and has a transparent background. It is comparatively larger in size.

Which Image Format You Should Use?

The basic rule is if the image is text-heavy, PNG should be your go-to because it is crisper and has high clarity. In addition, graphs, diagrams, and infographics — they all should also be in PNG format so that they have better readability.

On the other hand, if the image is just a regular photograph or real-life image, JPG is a better choice. Because it is meant just for viewing and not read; even when the image has blurred edges, it won’t be much of a problem.
