Pixel Refiner

Turn blurry, scaled, or AI-generated pixel-art-style images into clean, usable sprites.

Pixel Refiner runs entirely in your browser. Your images are never uploaded to a server.

What it does

• Detects the underlying pixel grid and resamples at the right size

• Removes anti-aliasing and makes backgrounds transparent

• Reduces colors and maps images to retro console palettes

• Adds dithering, outlines, auto-trimming, and exact resizing

• Processes multiple images and exports them together as a ZIP

Good to know

Pixel Refiner is an image conversion and optimization tool, not a manual pixel-by-pixel editor.
