How a Logo Gets Composited Onto a Photo Without Looking Pasted On

The three variables that matter

Placing a logo, sticker or watermark onto a photo well comes down to three adjustable variables working together: where it sits, how big it is relative to the photo, and how opaque it is — get any one of them wrong and the overlay looks awkwardly pasted on rather than naturally composited.

Why size should scale with the base image, not be fixed

A logo overlay sized in a fixed number of pixels looks appropriately sized on one photo but comically oversized or invisibly tiny on a photo of a different resolution. Calculating the overlay's size as a percentage of the base image's width instead means it scales sensibly no matter what resolution photo it's placed on.

Why corners are the default position

Placing a watermark or logo in a corner, rather than the center, keeps it out of the way of the photo's main subject while still making it visible enough to serve its purpose — identifying the source or brand without obscuring the actual content people are looking at.

Opacity softens the overlay into the photo

A logo placed at full 100% opacity can look like a harsh sticker sitting on top of the photo, especially over busy or textured backgrounds. Reducing the overlay's opacity slightly lets some of the underlying photo show through, which is why subtle watermarks often use partial transparency rather than a solid, opaque logo.

Try it yourself

Our Add Images (Overlay) tool lets you control all three of these — position, size and opacity — to composite one image onto another cleanly.
