Crisp local scaling
Pixel Art Upscaler Without Blur
Enlarge sprites, icons, and low-resolution game art by whole-number steps while preserving each source pixel as a clean block.
Upscale pixel art locally
Choose a whole-number scale. Nearest-neighbor resizing repeats source pixels without smoothing or AI-generated detail.

Preserve the grid instead of smoothing it
Photo resizing blends neighboring pixels, softening one-pixel outlines and introducing colors outside the palette. Nearest-neighbor scaling maps every source pixel to an exact output block.
This is deterministic local resizing, not generative AI. It preserves the grid but cannot reconstruct missing shapes, correct a damaged sprite, or reverse JPEG artifacts.
How to enlarge pixel art cleanly
- 1
Use the cleanest source
Prefer an original PNG at its native grid size instead of a screenshot or social-media copy.
- 2
Choose a whole-number scale
Use 2×, 4×, or 8× so every source pixel becomes an equally sized block.
- 3
Inspect and export
Check outlines, transparent edges, and palette colors at 100% before saving PNG.
Designed for grid-based artwork
Game sprites
Create larger presentation or prototype assets without blurring sprite edges.
Pixel icons
Enlarge small icons for documentation, portfolios, and design review.
Pattern references
Make individual color cells easier to see without interpolated shades.
Scaling is not restoration
The result is a larger copy of the existing pixel grid, not newly recovered detail.
- JPEG ringing and pre-existing blur are enlarged with the artwork.
- Non-integer display sizes can still look soft when another app scales the export.
- Very large sources or 8× output may exceed browser memory limits.
Pixel art upscaling questions
Why does a normal resizer blur pixel art?
Bilinear and bicubic filters blend neighboring pixels. Nearest-neighbor scaling copies them without averaging.
Does this add AI-generated detail?
No. It only repeats the existing pixel grid, keeping the result faithful and predictable.
Which output format should I use?
Use PNG for crisp edges, limited palettes, and transparency. Avoid JPEG for final pixel art.
