JPEG: The Photo Standard
JPEG was created in 1992 and remains the dominant format for photographs on the web and in digital cameras. It uses DCT-based lossy compression, allowing users to balance file size against image quality. JPEG supports 24-bit color (16.7 million colors) but does not support transparency or animation. Common variants include JPEG/JFIF for web use and JPEG/Exif for camera metadata.
