  • Image compression - Wikipedia
    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
  • Image file format - Wikipedia
    An image file format is a file format for a digital image There are many formats that can be used, such as JPEG, PNG, and GIF Most formats up until 2022 were for storing 2D images, not 3D ones The data stored in an image file format may be compressed or uncompressed If the data is compressed, it may be done so using lossy compression or lossless compression For graphic design applications
  • List of archive formats - Wikipedia
    This is a list of file formats used by archivers and compressors used to create archive files
  • JPEG - Wikipedia
    JPEG compression artifacts blend well into photographs with detailed non-uniform textures, allowing higher compression ratios Notice how a higher compression ratio first affects the high-frequency textures in the upper-left corner of the image, and how the contrasting lines become more fuzzy
  • Lossless JPEG - Wikipedia
    Lossless JPEG is a 1993 addition to JPEG standard by the Joint Photographic Experts Group to enable lossless compression However, the term may also be used to refer to all lossless compression schemes developed by the group, including JPEG 2000, JPEG LS, and JPEG XL
  • Data compression ratio - Wikipedia
    Data compression ratio, also known as compression power, is a measurement of the relative reduction in size of data representation produced by a data compression algorithm
  • Lossy compression - Wikipedia
    Composite image showing JPG and PNG image compression Left side of the image is from a low-quality JPEG image, showing lossy artifacts; 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 discarding to represent the content These techniques are
  • Quantization (image processing) - Wikipedia
    Quantization, involved in image processing, is a lossy compression technique achieved by compressing a range of values to a single quantum (discrete) value When the number of discrete symbols in a given stream is reduced, the stream becomes more compressible For example, reducing the number of colors required to represent a digital image makes it possible to reduce its file size Specific
  • JPEG XT - Wikipedia
    JPEG XT (ISO IEC 18477) is an image compression standard which specifies backward-compatible extensions of the base JPEG standard (ISO IEC 10918-1 and ITU Rec T 81)
  • Data compression - Wikipedia
    Composite image showing JPG and PNG image compression Left side of the image is from a JPEG image, showing lossy artifacts; 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 [13] In these schemes, some loss of information is
