JPG (or JPEG), is a well-known file format for graphic images and pictures, particularly on internet. It was invented by the Joint PhotographicExperts Group (JPEG) and utilizes a compression algorithm which reduces sections of an image into chunks of pixels. It's capable of compressing images up to 10:1 ratio without any visible degradation, based upon your setting. This is among the main reasons JPG is now the de facto standard of images found on the internet.

But all that compressiondoesn't offer without the loss. JPGs are considered to be a "lossy" file format, which means that, during the compression procedure, redundant blocks are removed permanently. The greater the compression of a file in this way, the more data you lose , which in turn means the less appealing your final image is going to look following several iterations of the algorithm.

Here's an example of an image that has been way overcompressed.

DescriptionJPG - is a popular graphic format characterized by a higher image compression rate that leads to a drop in quality. It is based on the method of rendering smooth color renditions, offering the capability to often reduce the amount data stored in the image's recording. Due to its compact size, it's frequently requested by the webmasters of websites that allow you to manage the amount of traffic. The algorithm is often used on memory cards for digital video cameras. A JPG algorithm is ideally suited for compressing photos and images where realistic images with little contrast of colors are used. There is no reason to use this format for compression of drawings and various kinds of images. The contrast is strong between nearby pixels leads to noticeable artifacts.Technical detailsThe procedure to compress digital images in JPG format is accomplished in several stages. First, the photo is converted into the color space called YCbCr, and then it is divided into squares to determine upper range of the color spectrum. Then, the colors and the brightness are coded. JPEG employs a "lossy" compression system and discrete cosine transform technology. The format is the standard set by ISO as well as the International Telecommunication Union. The format's compression ratio is within the range from 10:1 to 100:1. In this scenario the loss in image quality could range from minimal to significant.

DescriptionJPEG is a very popular graphic file format, which is characterized by a high amount of compression which results in less image quality. It makes use of technology for recording smooth color renditions and providing the ability to reduce the amount and frequency of data in the process of recording images. Due to its small dimensions, it's often requested by website owners and allows you to cut down the time and effort. It is also commonly used in memory cards that are used in digital video cameras. In addition, the JPEG algorithm is ideal for compressing pictures and photographs when realistic scenes with very little contrast of colors are evident.

At first, the image is transformed into a color space called YCbCr. Then , it's divided into squares in order to determine the upper portion of the color spectrum. In the end, the colors and brightness are coded. JPEG employs an "lossy" compression system and discrete cosine transform technology. The format works as the standard used by ISO along with the International Telecommunication Union. The file compression ratio is within the range 10:1 up to 100:1. In this situation the quality of the image can range from small to large.
