Perfect for Web-ready images
Designers who work with web images find DeJPEG invaluable for rescuing otherwise unusable pieces of stock photography.
Sharpen color edges
One of the most popular uses of DeJPEG is to counteract unwanted color "bleeding" and information loss that occurs even in high-quality JPEG images. Topaz DeJPEG's color sharpening and edge restoration tools actually reconstruct softened color edges, bringing out previously unseen image details and restoring sharpness to damaged edges. This is highly useful in many Photoshop tasks like masking and also makes the image look much cleaner in general.
Turns low-quality shots into high-quality keepers
Point-and-shoot and camera-phone users take advantage of DeJPEG's extensive artifact reduction capabilities to enhance the quality of their snapshots.
Note: Although Finder indicates that this is version none, the developer refers to it as version 4.0.2.
