From VicMan Software:
"JPEG" is the default data format for digital photos. It is used in all digital cameras and most of the photo editing applications. If you set the image quality not to a 100% ("super-fine") in order to reduce the disk/memory stick space, your images become blotchy and get ruined with the JPEG artifacts.
Jpeg Enhancer is an advanced application that lets you remove the artifacts and a blotchy look from your images, making them look as if they have been saved at a 100% ("super-fine") quality. It is based on advanced science-intensive technology that lets you repair images quickly, smoothly and easily.
If you are a home user, it will help you to improve the quality of your digital photos. ItÃ¢Â€Â™s also a must-have tool for publishers, design studios and web pros, helping you to recover the overcompressed images, supplied by your clients, to make them ready-to-publish and ready-to-print.
