JPG is the most common, recognizable bitmap image format. Its uniqueness is defined by its ability to maintain quality after compression. The most useful feature for a user or graphic editor is that he/she can control how the file compresses. And in contrast to PNG, it’s very simple. The user can always choose how to reduce the size and quality of the image. As a result, a huge amount of disk space is saved.
JPEG is most commonly used to process to store full-color files with realistic images that contain inherent transitions in brightness and tone. It’s based on a 24-bit color palette and supports 16.7 million colors. If you see beautiful, vivid pictures on the Internet, they’re most likely in this format.
Also, you can use it for sharing graphic digital content; photos, scanned copies, digitized images containing smooth fades of coloring and shadows. It’s the most convenient for placing and transferring compressed copies over a network, as it takes up less space, compared to other formats. In practice, saving a photo with a minimum degree of compactness doesn’t affect its appearance or its quality.
