DesignWhat does “JPEG” mean?
A raster image file format that compresses photographs by discarding detail the eye barely notices. It produces small files, at the cost of some quality each time the image is saved.
Etymology
An acronym of Joint Photographic Experts Group, the committee of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) that created the image compression standard. The standard was published in 1992. The name became the common term for the file format itself.
Usage note
JPEG and JPG refer to the same format; the shorter form exists because early file systems limited extensions to three characters. The format uses lossy compression: each save at low quality discards more detail.
Synonyms
- JPG
Word family
- JPG
- JPEG 2000
Usage examples
This essentially means that raster images, like JPEG or PNG files, have a limited amount of quality that always pertains to the screen in which they are been visualized.
