常见问题解答

Can I adjust the opacity of the watermark?
Yes. The opacity slider ranges from 0 (invisible) to 100 (fully opaque). A setting of 30-50% is typically ideal for visible but non-intrusive watermarks on photographs.
Where can I position the watermark on the image?
Choose from 9 preset positions: 4 corners, 4 edge centers, and the image center. The watermark is rendered precisely at the chosen position regardless of image size.
Can I add a logo or image as a watermark instead of text?
This tool adds text-based watermarks. Use the Add Logo tool for image-based overlays. Both run entirely in your browser and require DCPixel PRO.
Will the watermark be visible if someone screenshots my image?
Yes. The watermark is burned directly into the image pixels. It cannot be removed by simply right-clicking and saving — it is as permanent as any other part of the image.
