Remove Image Background Skill

Remove the background from an existing image file in the project, producing a transparent PNG.

Available Functions

removeImageBackground(imagePath, ...)

Remove the background from an existing image file.

Parameters:

• imagePath (str, required): Path to the input image file
• outputPath (str, optional): Path to save the result PNG. Defaults to replacing the extension with _no_bg.png

Returns: Dict with outputPath key containing the path to the saved result

Example:

const result = await removeImageBackground({
    imagePath: "attached_assets/photo.jpg",
    outputPath: "attached_assets/photo_no_bg.png"
});
console.log(`Result saved to: ${result.outputPath}`);

When to Use

• User has an existing image and wants its background removed
• User uploads a photo and asks to make the background transparent
• Creating transparent versions of logos, product photos, or portraits
• Preparing images for compositing or overlay on other backgrounds

Best Practices

1. Output must be PNG: The output file must have a .png extension since transparency requires PNG format
2. Use default output path when possible: Omit outputPath to automatically save as <original_name>_no_bg.png
3. Supported input formats: Works with common image formats (PNG, JPG, JPEG, WebP, etc.)

Output Location

• Default output: Same directory as input, with _no_bg.png suffix
• Custom output: Any path ending in .png

Limitations

• Output format is always PNG (required for transparency)
• Very complex backgrounds or low-contrast edges may not be perfectly removed
• Works best with clear foreground subjects (people, objects, logos)
