Duotone Maker — free online photo tool
You found a great photo, but it doesn't quite match the look you're going for. Maybe you want everything in your two brand colors, or a poster with one clean mood. Recoloring it by hand is fiddly and slow. We added a free tool that does it for you — Duotone Maker — right in your browser.
What it does
You upload a photo, pick two colors, and get a duotone version of it right away. The darker parts of the image take on one color and the lighter parts the other. It's a nice fit for brand visuals, posters, and social media images that all need to share the same feel.
Nothing leaves your device
The whole thing runs in your browser. Your photo is never uploaded to a server and nothing is saved anywhere. When you close the tab, it's gone — your image stays on your own computer the entire time.
How to use it
- Open Duotone Maker and upload your photo.
- Pick your two colors and watch the preview update.
- Download the duotone image and use it wherever you like.
It's free with no limit. There are more small tools on the Apps page.
