The JPEG Standard: Discrete Cosine Transform (DCT) & Chroma Subsampling
Standardized by the Joint Photographic Experts Group and ratified under ISO/IEC 10918-1 (ITU-T Recommendation T.81), JPG (or JPEG) is the cornerstone format of digital photography and internet imagery. The algorithm operates by converting RGB color space into YCbCr—separating luminance (Y, perceived brightness) from chrominance (Cb/Cr, color difference).
Because the human visual cortex is significantly more sensitive to fine spatial luminance variations than to subtle color shifts, JPEG downsamples the chroma channels (typically 4:2:0 or 4:2:2). The image is partitioned into 8x8 pixel blocks and transformed via the Forward Discrete Cosine Transform (FDCT) into frequency coefficients. High-frequency spatial details (barely perceptible to the human eye) are quantized aggressively, followed by lossless Huffman entropy coding.
While JPG remains the global standard for photographic distribution, modern digital publishing workflows frequently demand format transcodings. Converting JPG to lossless PNG enables transparent compositing; WebP dramatically slashes web payload sizes for Core Web Vitals; PDF and DOCX package images for professional and enterprise documentation; and vector wrappers (SVG/EPS) enable high-resolution desktop publishing integration.
