Nearest-neighbor scaling keeps hard pixel edges. Downloads as PNG.

Enlarge without smoothing

Choose a still image and a whole-number multiplier. Each original pixel becomes a block of pixels of the same color. Nearest-neighbor scaling avoids blended edges that can make sprites and icons look fuzzy.

Why whole-number scales matter

A 32 × 32 sprite becomes 128 × 128 at 4×. Every source pixel occupies an equal 4 × 4 block. Fractional scales can give different source pixels unequal widths, changing the rhythm of a pixel drawing.

Use PNG for the result

PNG avoids adding JPEG artifacts around the hard edges. This tool cannot remove blur already baked into the source. Use the original pixel artwork when possible; animated files need an animation-aware workflow.
