Image Tool is a program created to scale images and convert image file formats. Source images can be various, like tiff, jpg, bmp, png, gif, pdf, or other extensions. Source Images can be dragged and dropped into the application's main window, or onto the application's icon.

There are buttons for quick resizes, or exact sizes can be typed in. Images can be output to tiff, jpg, gif, bmp or png.

Image Tool can also work directly in and out of the pasteboard, rather than with files. Image data from the pasted board (selected and copied from another application, such as Preview) can be selected as the source image.

After resizing, the scaled image can be copied into the pasteboard to be pasted into another application.
