✨ Auto Edge Refiner

Standard sharpening increases contrast across all pixels, which often introduces noise and artifacts. Edge refinement specifically detects boundary areas between objects and enhances only those transitions. It also applies anti-aliasing to smooth jagged "staircase" effects while preserving smooth gradients in flat regions.

Yes! The tool fully supports PNG images with transparency. Edge refinement is applied only to visible pixels, leaving transparent areas intact. For best results, export back to PNG format to preserve the alpha channel.

For eCommerce product images, the "Strong Edge" preset works best. It crisps up outlines and removes background fringing, giving your product a clean, professional cutout look. You can also increase Edge Strength to 80-90% for even more definition.

Absolutely not. Everything happens locally in your browser using JavaScript and Canvas API. Your images never leave your device — no uploads, no servers, complete privacy. This also means you can use the tool offline once the page is loaded.

We support JPG, JPEG, PNG, and WebP formats up to 50MB. Images are automatically resized to a maximum dimension of 1200px for optimal performance while maintaining aspect ratio. This ensures smooth real-time processing even on mobile devices.

Yes. Many automatic background removers leave soft, feathered edges. Use the "Smooth Edge" preset (Smoothing 50-70%, Strength 35%) to subtly firm up those edges without creating hard artifacts. Gradually increase Edge Strength for more definition as needed.
