What is JPEG?
JPEG (Joint Photographic Experts Group) is a photo-oriented raster format that uses lossy, DCT-based compression to dramatically reduce file size. Most JPEGs are 8-bit per channel in sRGB and apply chroma subsampling (commonly 4:2:0), which discards some color detail that humans notice less than luminance. Files may be baseline or progressive (for faster perceived loading). The .jpeg and .jpg extensions are interchangeable. JPEG supports EXIF metadata but not true transparency, layers, or animation, so it’s poor for logos, UI icons, or crisp text. Use PNG or SVG for graphics; consider WebP/AVIF for smaller photos. Choose a quality around 85–92 for web to balance clarity and size, and avoid re-saving repeatedly, which compounds compression artifacts like ringing and blockiness.
