Watermark product photos in bulk
Anchored or tiled, sized as a fraction of the image, and refused on the platforms that prohibit it.
Sized relative, not in pixels
A watermark set at 200 pixels looks reasonable on a 2000px main image, dominates a 1024px collection tile, and is larger than a 100px swatch. Size, margin and spacing are all fractions of the output width, so one setting reads the same on every variant.
It knows where watermarks are banned
eBay prohibits watermarks of any type on every listing photo, including ownership attributions. Amazon prohibits them on the main image. Walmart prohibits them on the main image. PrepShot blocks the combination and names the platform and the rule rather than warning and proceeding.
Light or dark, per placement
Contrast-aware placement picks a light or dark mark from the brightness underneath, judged per tile, so a mark over a dark product goes light while its neighbour on the white sweep goes dark.
Never on your free output
PrepShot does not put its own mark on anything you produce, on any tier. A tool whose job is producing clean product photographs cannot brand them and expect to be trusted.
