What is Duotone Image Maker?

The Duotone Image Maker maps the shadows and highlights of any photo to two custom colors for a graphic-design-style look, with an optional tritone mode that adds a third midtone color. Pick your colors (by swatch or hex), fine-tune intensity and contrast, preview against the original side by side, then export as PNG, JPEG, or WebP — or copy the result straight to your clipboard.

The tool converts your image to luminance values, then maps the darkest pixels to your shadow color and the brightest to your highlight color, with everything in between sitting on a gradient between them. Sixteen curated presets (Navy & Coral, Purple & Gold, Black & White, Sepia, Wine & Blush, Charcoal & Ice and more) cover most brand palettes, and the Swap button flips the two colors so you can compare a light-on-dark version in one click. The midpoint slider shifts where shadows give way to highlights, and the balance slider tips the whole image toward the darker or lighter color.

How to use

1. Upload any image — photos with strong contrast work best for dramatic duotone effects.
2. Pick your shadow color (mapped to dark areas) and highlight color (mapped to light areas). Use the presets for popular combinations or choose custom colors.
3. Use the intensity, contrast, midpoint, and balance sliders to fine-tune the effect, toggle the compare view to check it against the original, then download as PNG, JPEG, or WebP.

When to use

• Branded blog post hero images that need to match a specific color palette.
• Spotify-style playlist covers or podcast episode artwork.
• Newsletter headers where stock photos need to look intentional instead of random.

Result

A social media manager uploads a team photo, applies a deep navy (#1B2A4A) and coral (#FF6B6B) duotone, and gets a header image that matches the brand palette.

FAQ

What types of photo work best for duotone?

Photos with clear shadows and highlights, like portraits with directional lighting, architectural shots, or anything with strong shapes. Flat, low-contrast photos turn into one muddy color because there's no tonal range for the mapping to work with.

Why does my image lose all its detail?

Either the source is too low-contrast, or the two colors you picked are too similar in brightness. Try a darker shadow color paired with a much lighter highlight color, then increase the intensity slider to taste.

How is duotone different from a color filter or tint?

A tint just overlays one color across the whole image. A duotone uses two colors mapped to brightness, so dark areas and bright areas become different hues. It's why duotones look graphic and editorial instead of just 'filtered'.

Can I pick custom hex colors instead of the presets?

Yes. Type a hex code straight into the field next to either swatch, or click the swatch to open the full color picker and enter any hex, RGB, or HSL value. Presets are starting points; once you load one you can nudge the colors to match your brand exactly. Turn on Tritone for a third midtone color.

What download formats does it support?

PNG, JPEG, or WebP, all at the original resolution of your uploaded image. PNG keeps lossless quality and transparency, JPEG gives you the smallest file for sharing, and WebP lands in between with better compression than JPEG.
