You can use
FastStone Capture instead. It is a much better snipping tool anyhow.
Jing is another excellent option. Advantage with it is that you can program it to a function key. And do not worry that you have to sign in for it. That has no consequences whatsoever. But you can also save pictures from PP directly. Just roll down the "save as type" and select .jpg, .png or .tiff.
