JPEG 

JPEG is the widely used image compression format. And it’s an abbreviation for joint photographic experts group. It is a process of compressing digital images and maintaining high image quality. JPEG is used explicitly for photos and other images with details and complex color gradients.

Re-saving the JPEG images will lead to a cumulative loss of image quality. Every time you save the image, it will introduce the image to an additional compression artifact. So, using the original and uncompressed image in a different format is recommended, and then saving it to the JPEG version you can eventually share or publish online.

It is a standard format for sharing and storing photos on the Internet. This is also compatible with many photo editing and viewing software. It is also used in many companies for sharing or publishing images.

JPEG will support complete grayscale and full-color images. It is also suitable for artwork, photographs, and other images requiring various colors. This is why it is used in most places. It also preserves image quality without losing data, but these images usually result in larger file sizes.

You can also adjust the compression levels when saving the image in JPEG format. The higher the compression levels, the smaller the file size, but there will be a noticeable loss of image quality. The principal aim of JPEG is to maintain good image quality. So, it combines techniques like color subsampling to add discrete cosine transformation to achieve this balance.

It also supports progressive encoding that will allow images to be displayed at lower quality levels and gradually improve the quality as the image data is loaded. This feature lets you use web images to provide a better experience while loading images on slow connections.
