How do I add a background color to a transparent image?

Drop or select your transparent PNG, JPG, or WebP image. Choose a background color from the presets (white, black, navy, pink, red, gray) or pick any custom color with the color picker. Click "Add Background" to apply, then download the result as a high-quality PNG file.

Is it safe to add backgrounds to images online?

Yes. This tool never uploads your images to any server. All processing happens entirely in your browser using standard web technologies. Your files stay on your device the entire time — nothing is sent anywhere.

What image formats are supported?

You can upload PNG, JPG, and WebP images. The tool works best with transparent PNGs, where the solid background color fills the transparent areas behind your design. The output is always a high-quality PNG file with your chosen background color.

Can I use a custom color for the background?

Yes. In addition to the six preset colors (white, black, navy blue, pink, red, and gray), you can use the custom color picker to choose any color you want. The hex code is displayed so you can match exact brand colors or any specific shade you need.
