🎨 Background Color Replacer

The tool scans every pixel in your image and compares it to your selected source color. When a pixel matches (within your tolerance setting), it gets replaced with your chosen target color. Edge smoothing creates natural transitions, and the strength slider controls how completely the color is replaced.

Color tolerance determines how closely a color must match your selected source color to be replaced. Low tolerance (0-20) only replaces exact matches — perfect for solid, uniform backgrounds. High tolerance (50-100) replaces similar colors too — ideal for gradient backgrounds, shadows, or when your background has slight variations.

Yes! You can repeat the process with different source colors to replace multiple colors. For example, you could first replace a white background with blue, then replace any red accents with green. Each replacement builds on the previous result.

For Amazon product photos, start by uploading your product image. Use the eyedropper to pick the existing background color (often white or gray). Set tolerance around 20-40 for clean edges, then choose pure white (#FFFFFF) or your desired color. Use Edge Smoothing at 30-50% for professional transitions between product and background.

Yes! If your PNG has a transparent background, the tool will preserve that transparency. You can add a colored background by setting your source color to match the transparent areas and replacing with your desired color, or simply use our white background tool for solid backgrounds.
