JPEG

What is a JPEG?

JPEG, which stands for Joint Photographic Experts Group, is an image file format popular on the internet for its ability to retain photo quality under compression. JPEGs are indicated by the file extensions .jpeg or .jpg.

How does a JPEG work?

JPEG is a lossy compression type, meaning it reduces the quality of the original image. JPEG is an ideal format for photos that feature smooth transitions of tone and color, but less apt for graphics, text, and drawings where contrast between pixels is sharp. JPEGs are also not the best format for repeated editing, as repeated compression will reduce image quality over time.
