Image compression is a type of data compression applied to digital images, to reduce their cost for storage or transmission. Algorithms may take advantage of visual perception and the statistical properties of image data to provide superior results compared with generic data compression methods which are used for other digital data.

Composite image showing JPG and PNG image compression. Left side of the image is from a low-quality JPEG image, showing lossy artefacts; the right side is from a PNG image. In information technology, lossy compression or irreversible compression is the class of data compression methods that uses inexact approximations and partial data ...
Composite image showing JPG and PNG image compression. Left side of the image is from a JPEG image, showing lossy artefacts; the right side is from a PNG image. In the late 1980s, digital images became more common, and standards for lossless image compression emerged. In the early 1990s, lossy compression methods began to be widely used. [14]

The iPhone [5] (retroactively referred to as the iPhone 2G [6] or iPhone 1 [7]) is the first iPhone model and the first smartphone developed and marketed by Apple Inc. After years of rumors and speculation, it was officially announced on January 9, 2007, [ 8 ] and was released in the United States on June 29, 2007.
The study, which was published in the journal Chemosphere, detailed how high levels of these flame retardants were found in kitchen utensils, food containers, trays used to hold meat and even toys ...
Lossless compression of digitized data such as video, digitized film, and audio preserves all the information, but it does not generally achieve compression ratio much better than 2:1 because of the intrinsic entropy of the data. Compression algorithms which provide higher ratios either incur very large overheads or work only for specific data ...
