What is JPG file format?

JPEG, short for Joint Photographic Experts Group, is a highly utilized file format for storing and compressing digital images. Specifically, the JPG file format, a variant of JPEG, employs lossy compression techniques to reduce file size. This format is particularly well-suited for photographs and images containing intricate color gradients. Due to its wide support in image editing software and web browsers, JPG is a favored choice for online image sharing. Moreover, it boasts compatibility with various operating systems and devices, including smartphones, tablets, and digital cameras.

The key advantage of the JPG file format lies in its ability to compress image files while preserving reasonable image quality. This attribute facilitates the storage and dissemination of large collections of high-quality images without occupying excessive storage space or causing lengthy download times.
