Pixel Art Resizer

A 16 × 16 sprite enlarged by 4× becomes 64 × 64. Each original pixel occupies a 4 × 4 square, so outlines, spacing and repeating patterns keep their proportions. This is a useful choice for game sprites, avatars, presentation graphics and artwork that needs a larger export without a new drawing style.

A custom size such as 16 × 16 to 50 × 50 still has sharp edges, but some source pixels become three pixels wide and others four. Nearest-neighbor scaling does not blend their colors; it cannot make unequal pixel widths uniform. Choose a whole-number multiplier when that regular grid matters.

Nearest-neighbor resizing chooses an existing source pixel for each output position instead of mixing neighboring colors. This tool copies its red, green, blue and alpha values together. Transparent areas remain transparent, and existing semi-transparent edges remain semi-transparent. The checkerboard is only a viewing aid.

Resizing does not repair a blurred source, remove JPEG artifacts, reduce the palette or turn a photograph into a carefully drawn sprite. Start with the original small PNG when possible. To convert a photo into pixel art or redraw individual pixels, use the related converter or pixel editor below.

Downscaling removes samples. A one-pixel outline, highlight or gap may disappear, even when the output edges remain crisp. Review the reduced result at 100%, then make any artistic corrections in an editor. Repeatedly shrinking and enlarging cannot recover the discarded detail; every change here is calculated from the loaded original.

You can resize a static sprite sheet as one image. Integer enlargement keeps frame dimensions and spacing in the same proportion. This tool does not split frames, update an animation atlas or export animation. It accepts static PNG, JPEG and WebP images; animated files in a supported format are flattened to the browser-decoded still image.
