    en.wikipedia.org/wiki/Image_file_format

    Image file format. 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 ...

    en.wikipedia.org/wiki/JPEG

    JPEG ( / ˈdʒeɪpɛɡ / JAY-peg, short for Joint Photographic Experts Group) [ 2] is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality.

    en.wikipedia.org/wiki/JPEG_2000

    JPEG 2000 (JP2) is an image compression standard and coding system. It was developed from 1997 to 2000 by a Joint Photographic Experts Group committee chaired by Touradj Ebrahimi (later the JPEG president), [1] with the intention of superseding their original JPEG standard (created in 1992), which is based on a discrete cosine transform (DCT), with a newly designed, wavelet-based method.

    en.wikipedia.org/wiki/Image_conversion

    Besides uncompressed formats and lossless compression formats that can usually be interconverted without any loss of detail, there are compressed formats such as JPEG, which lose detail on nearly every compress. While a conversion from a compressed to an uncompressed format is in general without loss, this is not true the other way around. Even ...

    The JPEG File Interchange Format ( JFIF) is an image file format standard published as ITU-T Recommendation T.871 and ISO/IEC 10918-5. It defines supplementary specifications for the container format that contains the image data encoded with the JPEG algorithm. The base specifications for a JPEG container format are defined in Annex B of the ...

    There are 4 basic choices for image file formats : SVG for simple diagrams (especially those that need to be scaled). JPEG for photographic images. GIF for animated images. PNG for everything else. While some formats offer multiple compression systems, in general the format and the compression system are tied together.

  9. Lossless JPEG - Wikipedia

    en.wikipedia.org/wiki/Lossless_JPEG

    General description. JPEG-LS is a lossless or near-lossless compression standard for continuous-tone images. [6] Its official designation is ISO-14495-1/ITU-T.87. [7] It is a simple and efficient baseline algorithm which consists of two independent and distinct stages called modeling and encoding.
