Does the overlay tool support transparent backgrounds?

Yes. PNG files with transparent backgrounds work as overlays, so logos, signatures, and stickers show through cleanly on any base image without a white or colored box around them.

Can I overlay more than two images?

Yes. You can stack unlimited overlay layers. Add as many images as you need, adjust each layer's position, size, rotation, opacity, and blend mode, then reorder them to control which appear on top.

What blend modes are available?

The tool offers 12 blend modes including Normal, Multiply, Screen, Overlay, Soft Light, Hard Light, Difference, Exclusion, Color Dodge, Color Burn, Lighten, and Darken. Each creates different color interactions between layers.

What format does the output download in?

The composed image downloads as PNG to preserve any transparency and maintain full quality.

Are my images uploaded to a server?

No. All processing runs in your browser using the Canvas API. Your images never leave your device.

Yes, completely free with no account required.
