With other photo software, each time you load and save a photo it becomes more distorted and gradually deteriorates. Webstyle retains a memory of the original master file and every time you alter the image, even if you load a processed or 'after' image, it actually performs the requested operation using the original master.
This even allows you to perform 'miracles' such as to load a cropped JPEG photo, no matter how long ago you produced it, and then 'un-crop' and restore the removed parts of your picture (assuming your master image is available on your file system somewhere). This also means there is no cumulative distortion or deterioration, no matter how many times you load and edit your photos. You can even load an old JPEG photo and undo any changes you made. Do that with any other software!
* speed tests by Xara show Webstyle can perform fully anti-aliased image scale and rotate on large images many times faster than any other image editor we could find.
