Make sprites bigger without blurry edges, or turn enlarged and AI-generated pixel art back into clean 1× pixels.
Ordinary image resizers blend neighboring pixels to make photos look smooth. For pixel art, that blending turns crisp edges into a blurry mess. This tool uses nearest-neighbor scaling: every pixel becomes an exact square block of the same color.
AI image generators and screenshots often produce "pixel art" where each pixel is really a 6×6 or 8×8 block, with slightly uneven colors and soft edges. Restore 1× detects the block size, shrinks the image to one pixel per block, and averages away the noise. You get a real sprite you can edit, recolor and scale cleanly, for example with Then scale 4×.
Quick answers about the pixel art scaler tool.
Drop the image, choose Scale up and a whole number like 4×, then download. Every pixel stays a sharp square.
It copies each pixel into a block instead of blending colors, so edges stay hard. It is the right method for pixel art and retro graphics.
Often, yes. Restore 1× finds the grid of blocks and averages each block into one pixel. It works best when the blocks are roughly even.
The image has no regular blocks, either because it is already at 1× or because it is not real pixel art.
Results can be up to 16,384 pixels per side. Larger scales are reduced automatically.
