Frequently asked questions
For a product listing, mark a preview copy and deliver the clean artwork after checkout. A corner credit is unobtrusive; a centre mark is more visible. Neither placement prevents someone from copying a picture.
Can I change the visibility of the text?
Yes. Use the opacity control and switch between light and dark ink. Run the tool again to compare versions.
Will the original image be overwritten?
No. The output is a new PNG. Keep the clean master for the buyer and use the marked image for your listing.
Can this watermark a whole animated image?
No. The tool exports one still frame, not an animated WebP or a video.
