Turn an image into a custom duotone

Designers and communicators can align a photograph with brand colors or create a strongly stylized poster from an ordinary source image.

Map every shade between two colors of your choice and produce a cohesive duotone treatment suited to a distinctive visual identity.

How to use

  1. Bring in a PNG, JPEG or WebP image whose size does not exceed 20 MB.
  2. Choose one color for the shadows and another for the lights using the available color controls.
  3. Run the effect so every shade in the photo is mapped between those two colors.
  4. Study the preview and change the hues if the subject does not stand out enough.
  5. Download the file when the duotone look matches the mood you want.

Example

A small brand needs a poster that matches its palette. The designer uploads a portrait, picks a deep navy for shadows and a pale gold for highlights, applies the duotone effect, and downloads an image that fits the campaign.

Limits and formats

Where processing happens

The duotone mapping is performed by your browser on the device you are using. No file copy is sent out for this operation, so the source image stays where it is and the stylized version is created locally.

Frequently asked questions

How should I pick shadow and highlight colors?

Use a darker tone for shadows and a lighter one for highlights. If the result feels flat, increase the contrast between the two colors or swap them to compare a different mood.

Can I apply this effect to a logo?

Yes, as long as the logo is a PNG, JPEG or WebP image. Simple shapes often work well, but fine gradients and small text may lose clarity after the color remapping.

Is the original image changed permanently?

No, the tool creates a new processed version while your source file remains untouched on your device. You can reload the original whenever you want to try another color pair.
