How to use Replace PNG Colors with a Single Tone
- 1. Upload the PNG. Add the image you want turned into a flat silhouette, such as logo.png, keeping its transparency intact for the conversion.
- 2. Choose the silhouette tone. Pick the Silhouette tone that every visible pixel will be replaced with, such as #000000, while the original alpha channel stays untouched.
- 3. Download the silhouette PNG. Save the result, such as logo.png with all colors flattened to black with alpha preserved, once the flat tone matches your design.
When to use Replace PNG Colors with a Single Tone
Replace PNG Colors with a Single Tone flattens an entire image's color map into one solid silhouette tone while preserving its shape and transparency. It is the fastest way to turn any colored graphic into a flat, single-color icon.
- Creating a favicon silhouette from a full-color logo. A full-color logo.png needs a simplified black silhouette version for a favicon or a monochrome app icon slot that only supports one flat tone.
- Building a matching set of solid-color icons. A design system needs an icon set available in a single accent color for a specific UI state. Replacing each icon's colors with that one tone produces the variant.
- Making a stencil-ready graphic. A multi-color illustration needs to become a flat single-tone shape before it can be cut as a stencil or laser-engraved template.
Examples

logo.png + #000000
