JPG has become the world's most widely used image format, dominating digital photography, web images, and photo sharing across all platforms.

Using sophisticated lossy compression algorithms, JPG files achieve remarkable file size reductions while maintaining acceptable visual quality for photographic content. This breakthrough in image compression technology enabled the digital photography revolution and remains the backbone of image sharing on the modern internet.
