Frequently asked questions
Can I use my logo as a watermark?
The image watermark tool supports text overlays. For logo watermarks, use the text mode with your brand name.
What is mosaic mode?
Mosaic mode repeats the watermark in a tiled pattern across the entire image, making it very difficult to crop or edit out.
Will the watermark reduce image quality?
No. The watermark is applied as an overlay without recompressing the original image content.
Can I control which part of the image has the watermark?
Yes. Choose from 9 position options (top-left through bottom-right, including center) or use mosaic for full coverage.
