FAQ
Can I pick any position?+
9 preset positions plus fine-tuning. Bottom-right is most common and least likely to obstruct content.
Are transparent PNG logos better?+
Yes. PNGs with transparent backgrounds blend naturally. White-background logos can show a visible rectangle.
What opacity works well?+
30~50% looks good. Too dark obscures content; too light is barely a watermark.
My watermark is getting cut off.+
It's likely too large or placed too close to the edge. Adjust size and position.
Can I batch-apply to multiple images?+
Currently one at a time. Apply the same settings sequentially for multiple photos.
What if I want a text watermark?+
Use the [Add Text to Image] tool — supports text, outline, and positioning.
