Overlay a logo or brand image onto a photo as a watermark — control size, position, and opacity.
Frequently asked questions
PNG with a transparent background works best, so only the logo itself shows and not a solid box around it — JPG/WebP also work, but any background color in the logo image will show as a rectangle.
The scale setting sets the logo's width as a fraction of the base photo's width — e.g. 0.2 makes the logo 20% as wide as the photo, scaled proportionally.
