About Duotone Image
Map highlights and shadows to two chosen colors for a graphic treatment. Turn a photograph into a two-color poster treatment, useful for campaign artwork and coordinated graphics.
How the browser tool works
Each source pixel is mapped between your chosen shadow and highlight colors according to its brightness. The result is exported as a new raster image, so subtle original hues are intentionally replaced. Files are processed in the browser workspace; compare the preview and the actual downloaded result.
How to use it
- Choose a supported source file in the workspace above.
- Adjust the available options and inspect the preview or settings.
- Process the image and examine the downloaded file at its intended size before publishing.
Limits and privacy
Color changes are baked into the output; retain the original for other edits.
The workspace works locally in your browser; selected source images are not sent to this site's application server. Some features load third-party code from a CDN, and large images may run out of device memory. Keep a backup of your original.
Questions about Duotone Image
Can I keep the original colors?
Keep the source file. A duotone output does not carry enough color information to reverse the mapping.
Does it change my source file?
No. The browser creates a separate result for download. Keep the original if you may need another adjustment.
