Why Use Image Debander?
Color banding and gradient artifacts can ruin a professional design. Our tool uses advanced dithering and smoothing algorithms to restore image quality.
Smooth Gradients
Fix "staircase" artifacts in skies, backgrounds, and shadows. Our algorithm intelligently identifies banding and applies smooth transitions.
Dithering Grain
Add subtle, high-frequency grain to break up flat areas. This classic digital technique prevents the eye from seeing steps in color transitions.
Restore Privacy & Quality
Debanding can also help hide metadata artifacts and compression noise. All processing is private and happens locally in your browser.
How to Deband Your Images
Upload Your Images
Drag and drop one or many images. We support most common formats and handle high-resolution files.
Fine-Tune Smoothing
Adjust the smoothing strength and radius. Add grain to achieve a professional film-like or clean finish.
Download High Quality
Preview results in real-time and download all your debanded images as a ZIP file or individually.
Frequently Asked Questions
What causes color banding?
Banding happens when there are not enough colors to represent a smooth gradient, often due to low bit-depth (8-bit) or heavy compression in JPEGs.
How does the debander work?
It uses a spatial filter to identify edges and flat areas, then applies dithering and smart interpolation to fill in the missing color steps.
Will it blur my image?
No, the algorithm is edge-aware. It targets gradients while preserving sharp details in textures and lines.
