Basic Knowledge
What is a Watermark
A watermark is a character or logo displayed over an image to prevent unauthorized reproduction, indicate the creator, or show the website name.
Meaning of Settings
- Opacity：Opacity refers to the degree of visibility of the overlaid watermark. The closer to 0%, the more the original image shows through; the closer to 100%, the more opaque the watermark appears.
- Tile Layout：Tile layout is a method of repeatedly placing watermarks across the entire image. Since the watermark remains even if part of the image is cropped, it is highly effective at preventing unauthorized use.
