The duotone effect is a popular design technique used by Spotify, editorial magazines, and modern web design. It converts your image to grayscale, then maps dark tones to one color and bright tones to another.

Frequently Asked Questions

What is a duotone effect?

Duotone maps the shadows and highlights of an image to two custom colors. Dark areas become one color, bright areas become the other, with smooth transitions between them.

Can I choose my own colors?

Yes! Use the two color pickers to set any shadow and highlight color. You can also start from one of the 8 built-in presets.

Does it work with any image format?

Yes — JPG, PNG, and WebP images are supported. The output is always a high-quality JPEG or PNG.
