DescriptionThe JPEG format, often seen as .jpeg or .jpg, is a creation of the Joint Photographic Experts Group. It's widely used for storing and transmitting digital images, including those taken by digital cameras. It uses lossy compression to reduce file size, sacrificing some image data for a smaller file. This trade-off balances image quality and file size.
Technical detailsJPEG typically uses the YCbCr color model, allocating 8 bits per channel. It also supports other color models like sRGB, RGB, and CMYK. You can adjust the compression level to meet your needs, which affects both file size and image quality. Higher compression results in smaller files but lower quality; lower compression yields larger files and better quality. JPEG files can be compressed with minimal quality loss, but expanding them might reduce quality. The JPEG format can include a lot of metadata, such as camera settings and copyright information. It also features progressive JPEGs, allowing images to load gradually on slow connections. JPEG is highly compatible with most devices and platforms, making it ideal for photographic content. However, due to its lossy compression, it might not be the best choice for images with sharp contrasts, like line drawings or text.
