Joint photographic experts group. It is currently one of the most commonly used image formats. Its major advantage is the compression algorithm that is defined by the standard. This is a raster graphics format, which means that it is pixelated.
JPEG is a widely used image format that is commonly used to store and share photos. It was developed in the 1990s
as a standard for compressing and encoding digital images, and has since
become the most popular image format in the world.
The development of JPEG files began in the early 1990s as a response to
the growing demand for digital images. At the time, there was a need for a
standard image format that could be used across different devices and
platforms. A group of experts from the International Organization for
Standardization (ISO) and the Consultative Committee for Documentary
Standard (CCSDS) came together to create a new image format that could
provide high-quality images with minimal file size. After several years of
development, the JPEG standard was published in 1992.
JPEG files are known for their high compression ratio and lossy data
representation. This means that when a JPEG image is compressed, some of
its color information is discarded to reduce the file size. The amount of
compression can be adjusted by changing the quality setting, which
trade-offs between file size and image quality.
Other features of JPEG files include :
- Support for different color depths (1, 2, or 4 bits per pixel)
- Support for different image sizes (from tiny thumbnails to large prints)
- Ability to store metadata such as date, time, and camera settings
- Wide range of applications, including web galleries, social media, and print media
