Frequently Asked Questions
Can I use a logo as a watermark?
This tool stamps text watermarks. For logo watermarks, add your logo over the image using a graphic editor or use the Add Text tool for a brand name.
How do I make the watermark subtle?
Lower the opacity to 20-40% and rotate it 30-45 degrees. Diagonal watermarks across the center are harder to crop out.
Can the watermark be removed by others?
A watermark can be cropped out if it sits in a corner. Tiling it across the image makes removal much harder.
