JPEG or PNG?

[jeromebunker]

In posting pictures, there are sites which prefers JPEG and others wants PNG. I wonder what is the difference between them? When do you use JPEG and PNG?

Both the popular file formats. JPEG wins hands down on file size, but there's an obvious trade-off in quality as you compress it more. PNG will always be better quality but a larger file. Both image formats are valid and used for websites but slower loading speed is not always caused by high-resolution images, it can also be caused by limited resources.

JPEG stands for Joint Photographic Experts Group while PNG stands for Portable Network Graphics with so-called lossless compression. JPEG file quality is significantly lower than that of the PNG files.
