JPEG vs PNG

JPEG is commonly used method of lossy compression for digital photography (image). The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. .jpg or .jpeg is the most common image format by digital camera and on website.

PNG is a raster graphics file format that supports lossless data compression. PNG supports palette-based images, grayscale images and full-color non-palette-based RGB[A] images. .png format is often used for transferring images on the Internet.

Summary:
JPEG format can produce a smaller file than PNG for photographic, since JPEG uses a lossy encoding method.
When storing images that contain text, line art, or graphics, the PNG format can compress image data more than JPEG can.
Early web browsers did not support PNG images.
JPEG does not support transparency.
