JPEG reduces file size by permanently discarding data that the human eye is less likely to notice, such as subtle variations in color.
It is the most common format for web images and digital cameras because it can compress photos to about 1/10th of their original size without significant loss in visible quality. JPEG vs. Other Formats 24 bit jpeg? - Adobe Community
JPEG stands for the , the committee that introduced the standard in 1992. It is primarily known for:
), which is often called "True Color" because it exceeds the number of colors the human eye can typically distinguish. How the JPEG Standard Works
Combined, these channels can produce approximately (
It uses a process called Discrete Cosine Transform (DCT) to convert image data into a mathematical form that is easier to compress.
A 24-bit JPEG is a digital image that uses to store color information. This is achieved by allocating 8 bits to each of the three primary color channels: Red: 8 bits (256 shades) Green: 8 bits (256 shades) Blue: 8 bits (256 shades)
