Duotone

Duotone is a browser-based design utility from ShapeFACTory that APPlies a two-color treatment to uploaded images. The duotone effect replaces the natural color range of a photo with a palette built from a dark shade and a light shade, producing the bold, high-contrast look often seen in editorial layouts, album art, posters, and modern web design. The tool runs in the browser and is AImed at people who want a quick visual effect without opening a full image editor.

What it does

You bring in a photo, and the tool maps its tones onto a chosen pair of colors. Dark areas of the image lean toward one color while highlights lean toward the other, creating a stylized graphic result. The interface is intentionally simple: the image sits at the center while palette controls let you explore different combinations, and the preview updates as you adjust settings. The ouTPUt can then be used in presentations, social posts, mockups, or as a background element in a larger design.

Key capabilities

• Instant duotone conveRSIon: Converts ordinary photos into two-tone graphics in a few CLIcks.
• Custom color pairs: Lets you set the shadow and highlight colors so the effect matches a brand or mood.
• Live preview: Shows changes immediately, making it easy to compare palette options before saving.
• Sample imagery: Includes example photos for Testing the effect before uploading your own.
• Downloadable results: Exports the treated image for reuse in other projects.
• No-install Workflow: Runs entirely in a modern web browser.

Who it is for

Duotone suits graphic designers, social media creators, presentation makers, and developers who need a consistent visual style across a set of images. It is also useful for marketers building campaign visuals and for anyone who wants a polished, magazine-like treatment without learning complex masking or channel techniques. Because the effect is applied quickly, it works well for rapid prototyping and mood boards.

How to get started

1. Open the Duotone page in a desktop browser.
2. Use a sample image or upload your own photo.
3. Adjust the two palette colors until the preview fits your intent.
4. Download the finished image and place it in your design or document.

Results look best with photos that have clear contrast between light and dark regions; flat or low-contrast images may produce a subtler effect.

Pricing and access caveat

The tool is presented as a free web utility from ShapeFactory, and no paid tier is described on the product page. Features, upload liMITs, export resolution, and availability may change without notice, so check the current site before relying on it for production work. Because it is browser-based, access depends on an internet connection and a compatible modern browser.
