Add background
Place a transparent cutout on a solid colour, gradient, or custom image background — for JPEG-only destinations and presentation slides.
What it does
Takes a transparent image (typically a PNG with alpha) and composites it on top of a chosen background. The output has no transparency — every pixel becomes opaque against the chosen background.
Background options:
- Solid colour — pick from a palette or enter a hex / RGB value.
- Linear gradient — pick two colours and an angle.
- Radial gradient — pick centre and edge colours.
- Custom image — upload another image to use as the background (scale-to-fit, cover, contain, or tile).
- Transparent checkerboard — for visualisation only; you'd never want to export this.
When you'd use this
- Producing a JPEG version of a transparent PNG for a destination that doesn't accept transparency (older email clients, some CMSes, certain marketplace listings).
- Mocking up a hero image by placing a product cutout on a brand-colour background.
- Putting a logo on a coloured tile for social-media avatars.
- Generating multiple colour variants of the same artwork for A/B testing.
Edge handling
Anti-aliased edges in the source are blended with the chosen background using the alpha channel as the weight. This produces visually correct results — no jagged edges, no halos from improper compositing.
If you originally had soft fuzzy edges (hair, fur) and the new background is very different in tone from the original removal, you may see a slight tint transfer. The Edge refinement tool can decontaminate those edges before adding the new background.
Difference from the Editor's Background panel
The Editor's Background panel is for interactive composition with live preview, brush touch-up, and adjustments. The Add Background utility is for the simple one-shot case: pick a colour, get a flattened file out, done.
