Frequently Asked Questions

What is the best watermark position?

Tiled (repeated) watermarks are hardest to remove and provide the best protection. Corner watermarks are less intrusive but easier to crop out. Center watermarks are visible but can obstruct the image.

How transparent should my watermark be?

30-50% opacity is ideal — visible enough to deter theft but not so opaque that it ruins the viewing experience. For preview/sample images, use 20-30%.

Can I add a logo as a watermark?

Yes. Select "Image" as the watermark type and upload your logo file (PNG with transparent background works best). You can adjust its size, position, and opacity.
