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.
JPEG stands for Joint Photographic Experts Group, an international organization that standardized the format during the late 1980s and early 1990s. It’s the go-to file format for digital images — and it has been ever since photographers began snapping and storing images on digital cameras and other reprographic devices. style.

JPEG uses a discrete cosine transform technique to compress photographs. This same compression method is used in many different types of media, including digital images, video, and audio. Since light and sound exist in nature as waveforms, it makes sense that using frequency encoding is the best way to process this type of data. JPEG compression fa...
The early internet was incredibly slow by modern standards. Images were measured in kilobytes, not megabytes. Early dial-up modems used for the internet had a data rate of 56 kilobits-per-second. That means a 10-megabyte JPEG photograph would require at least 23 minutesto completely download. Clearly, image dimensions were very restricted to minimi...
The amount of space saved by using JPEG compressed images instead of a RAW file or TIFF is enormous, particularly when considering the pace with which images are being uploaded to the internet. Any reduction in file size and bandwidth for a single photograph can be multiplied by hundreds of millions since that’s how many images are shared on social...
The purpose of a JPEG image is critically important in determining if it’s an appropriate format to use or not. Since JPEG is optimized for saving photographs, it tends to compress high-frequency data more strongly. In nature, one edge tends to blur into another and that is even true in photographs of manmade structures. Light reflects, bounces, an...
JPEG is the leading internet image format and virtually every modern device supports saving and viewing images with this encoding. Its efficiency was surpassed several years ago, but it’s difficult for any new format to gain enough support to become as widely adopted as JPEG. That is slowly changing and it might not be long before JPEG is considere...
JPEG files usually have a file extension of .jpg, however, .jpeg is not uncommon. Other extensions include .jpe, .jif, .jfif, and .jfi. These are all exactly the same and it’s usually okay to change the file extension. Since .jpg and .jpeg are the most popular, however, it’s probably best to use that ending to avoid any compatibility issues with ap...
JPEG was finalized as a digital image standard by the Joint Photographic Experts Group in 1992. This joint committee is part of larger international standards organizations, ISO/IEC and ITU-T. The work on standardizing photographic quality graphics began in 1983 and began narrowing in on JPEG as a good candidate soon after. The DCT compression algo...
JPEG format is both wonderful and terrible in equal parts and which side takes precedent is largely within the control of the user. If used wisely, JPEG can prevent wasting resources, both storage space and bandwidth benefit greatly from the use of compressed images. If care isn’t taken, however, and the format is abused, the resulting photographs ...

Jul 7, 2021 · A JPG or JPEG file (both pronounced "jay-peg") is an image file. While some JPG image files use the .JPG file extension and others use .JPEG, they are both the same type of file. Some JPEG Image files use the .JPE file extension, but that's not very common. JFIF files are JPEG File Interchange Format files that also use JPEG compression, but ...
