Used to set the attributes when an image is to be saved in JPEG format. Two files, that is, the original image to be saved and the image to which the specified attributes is applied are displayed. The size of each file size is also displayed.
[Drag] button
Used to switch the preview display mode in entire image mode and actual size mode. In actual size mode, you can check the image carefully by dragging it with the mouse.
[Quality] group
Used to adjust the quality of an image. Moving the slider to the left increases the image compression and reduces the file size. The quality of the image is low, however. On the other hand, moving the slider to the right reduces the degree of image compression but the image quality is good. The main drawback is that the file is large.
[Property] group
[Progressive] checkbox
Select this option when you wish to use progressive JPEG. With progressive JPEG, a browser displays an image gradually, from low resolution to high resolution, which ultimately produces a clear image.
