Continuously varied JPEG compression (between Q=100 and Q=1) for an abdominal CT scan. JPEG (/ ˈ dʒ eɪ p ɛ ɡ / JAY-peg, short for Joint Photographic Experts Group and sometimes retroactively referred to as JPEG 1) [2] [3] is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography.
For example, Adobe explains, "The primary use of JPEGs is for images, whereas PDFs can handle all sorts of text and image-based documents. Because JPEGs compress image data, its file sizes tend to ...

For example, graphically simple images (i.e. images with large continuous regions like line art or animation sequences) may be losslessly compressed into a GIF or PNG format and result in a smaller file size than a lossy JPEG format. For example, a 640 × 480 pixel image with 24-bit color would occupy almost a megabyte of space:
JPEG 2000 – an image format standardized by ISO/IEC; JPEG XL – an image format designed to outperform and replace existing formats. Especially legacy JPEG. Supports both lossy and lossless compression. MNG – moving pictures, based on PNG; OpenEXR – a high dynamic range imaging image file format, released as an open standard along with a ...
Thumbnail images being used to show a sample of image files within a folder, on a computer operating system. Thumbnails are reduced-size versions of pictures or videos , used to help in recognizing and organizing them, serving the same role for images as a normal text index does for words.

JPEG Network Graphics (JNG, / ˈ dʒ ɪ ŋ /) is a JPEG-based graphics file format which is closely related to PNG: it uses the PNG file structure (with a different signature) as a container format to wrap JPEG-encoded image data. JNG was created as an adjunct to the MNG animation format, but may be used as a stand-alone format. JNG files embed ...
