Can I use a logo with a transparent background?

Yes — a PNG or WebP logo with transparency blends naturally onto the photo; a solid background will appear as a colored box.

Does the watermark scale with image size?

Yes — logo size is set as a percentage of the photo's width, and margins scale with image size, so the watermark looks proportional on both small and large photos.
