About JPG
JPEG (Joint Photographic Experts Group)
A lossy image format standardized in 1992 that shrinks photos by discarding detail the eye is less likely to notice. It has no transparency, and each re-save loses a little more quality. Use it for photos you want to share or upload, since nearly every device, browser and app opens it.
About PNG
Portable Network Graphics
A lossless raster format published in 1996 as a patent-free replacement for GIF. It compresses with DEFLATE and supports full alpha transparency. Use it for screenshots, logos and graphics with sharp edges or text, where JPG compression would leave visible artifacts.
