Tiled watermark vs grid placement?

Tiling repeats across the image for anti-theft protection. Grid mode pins one mark to corners or center—ideal for logos.

What if batch images have different dimensions?

Positions use percentage anchors per image, so landscape and portrait shots keep consistent watermark placement and scale.

Do transparent PNG watermarks work?

Yes. PNGs with alpha channels overlay cleanly without opaque rectangles blocking the photo.
