[[adni]] (Joint Photographic Experts Group) is a [[lossy compression]] method; JPEG-compressed images are usually stored in the '''[[JFIF]]''' (JPEG File Interchange Format) or the '''[[Exif]]''' (Exchangeable image file format) file format. The JPEG [[filename extension]] is '''JPG''' or '''JPEG'''. Nearly every digital camera can save images in the JPEG format, which supports eight-bit grayscale images and 24-bit color images (eight bits each for red, green, and blue). JPEG applies lossy compression to images, which can result in a significant reduction of the file size. Applications can determine the degree of compression to apply, and the amount of compression affects the visual quality of the result. When not too great, the compression does not noticeably affect or detract from the image's quality, but JPEG files suffer [[Generation loss|generational degradation]] when repeatedly edited and saved. (JPEG also provides lossless image storage, but the lossless version is not widely supported.)
▲The '''GIF''' ([[Graphics Interchange Format]]) is in normal use limited to an 8-bit palette, or 256 colors (while 24-bit color depth is technically possible).<ref name=aminet>{{cite web|url=http://uk.aminet.net/docs/misc/GIF24.readme |title=GIF 24 Bit (truecolor) extensions |author=Andreas Kleinert |year=2007 |access-date=23 March 2012 |url-status=dead |archive-url=https://web.archive.org/web/20120316215949/http://uk.aminet.net/docs/misc/GIF24.readme |archive-date=16 March 2012 }}</ref><ref name=philhoward>{{cite web|url=http://phil.ipal.org/tc.html |title=True-Color GIF Example |author=Philip Howard |access-date=23 March 2012 |url-status=dead |archive-url=https://web.archive.org/web/20150222123613/http://phil.ipal.org/tc.html |archive-date=22 February 2015 }}</ref> GIF is most suitable for storing graphics with few colors, such as simple diagrams, shapes, logos, and cartoon style images, as it uses [[Lempel–Ziv–Welch|LZW]] lossless compression, which is more effective when large areas have a single color, and less effective for photographic or [[dither]]ed images. Due to GIF's simplicity and age, it achieved almost universal software support. Due to its animation capabilities, it is still widely used to provide image animation effects, despite its low compression ratio compared to modern video formats.
