Frequently Asked Questions
Can I use a transparent PNG logo as a watermark?
Yes! Upload any transparent PNG logo, and it will blend over your photo with customizable opacity.
What is the "Tile" watermark option?
The Tile option repeats the watermark diagonally across the entire image, making it impossible for anyone to crop out your copyright mark.
