JPG

Joint Photographic Experts Group JFIF format

JPG (or JPEG) is one of the most widely used image file formats, favored for its efficient lossy compression algorithm that significantly reduces file size while maintaining a high image quality. It is commonly used for photographs and web graphics; however, the lossy nature of its compression means that some image quality is sacrificed, and this loss can be exacerbated with repeated editing and saving. JPG files support 24-bit color, allowing for a broad spectrum of colors, but they do not support transparent backgrounds.

JNG

JPEG Network Graphics

JNG (JPEG Network Graphics) is an image file format similar to PNG, but it uses JPEG compression for bitmaps and offers support for color and grayscale images with or without transparency. This format was designed to provide a simpler, more efficient method for transmitting images over the internet, and it allows for lossy compression to reduce file size without a significant loss in quality for certain types of images. However, JNG is not as widely supported as other more common image formats like JPEG and PNG.
