Joint Photographic Experts Group JFIF format
A popular image file format known for its efficient compression techniques, enabling high-quality images with reduced file sizes. It is widely used for digital photography and web graphics, but the lossy compression can result in a loss of image quality, especially when the image is edited and saved multiple times.
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.
