Frequently asked questions
Does watermarking reduce image quality?
No: the watermark is drawn directly onto your pixels and the result is saved losslessly, so quality is unchanged.
Can I use a logo as a watermark?
Yes: choose a logo image and it is placed at any of the 9 positions with adjustable opacity and scale.
How do I stop someone cropping my watermark out?
Place the stamp across a busy part of the photo, not a plain corner, and use moderate opacity so it is visible but not distracting. Try the crop image tool to see which areas survive cropping.
