, which can pinpoint the precise location of the image. The Universal Standard

Because the human eye is more sensitive to changes in brightness than color, some color information is discarded without significantly affecting the perceived quality. IMG_20230302_113253_198.jpg

The image is converted from RGB (Red, Green, Blue) to YCbCr, which separates brightness (luminance) from color (chrominance). , which can pinpoint the precise location of the image

The image is divided into small blocks (usually 8x8 pixels), and the mathematical DCT is applied to represent these blocks as a sum of different frequencies. The image is divided into small blocks (usually

This is the primary "lossy" step where high-frequency information (fine detail) is reduced, significantly shrinking the file size. Metadata and Digital Footprints

Today, JPEG is the most widely used image format on the internet and in digital photography. Its ability to balance high-quality visuals with small file sizes makes it ideal for everything from social media sharing to professional archives. While newer formats like HEIF and WebP offer better compression, the universal compatibility of JPEGs ensures they remain the standard for digital communication.
