About Duotone Effect
Duotone, that bold two-color look where shadows and highlights each take their own hue, is everywhere in modern posters, music covers, and tech branding. Recreating it usually means layering gradient maps in design software, which is more steps than most people want for a simple striking effect.
The Duotone Effect maps your image to two colors of your choice, turning an ordinary photo into a graphic, on-trend image in one go. It works right in your browser with no account to create and no watermark on the download. The image you upload is removed from our servers after processing, so your photo stays private throughout.

FAQ
Can I choose the two colors myself?
Yes. You pick the two colors, typically one for the dark tones and one for the light tones, and the tool maps the image between them.
What's the difference between duotone and a simple tint?
A tint lays one color evenly over the whole image. Duotone uses two colors mapped to the image's shadows and highlights, giving a stronger graphic, high-contrast effect.
Does it work best with certain photos?
Images with clear contrast between light and dark areas show the strongest duotone effect, since the two colors map onto those tonal differences.
Can I use Duotone Effect on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
