How It Works
Upload sprites
Drop in one or many sprite images to resize in a batch.
Choose the target size
Choose a percentage or fit within maximum dimensions, then select nearest-neighbor or smooth resampling.
Download resized sprites
Export the batch with crisp, pixel-preserving scaling.
Compare nearest-neighbor and smooth resizing
Load the numbered 64 × 64 tile with Try an example. A 4× export is 256 × 256: nearest-neighbor repeats each source pixel in a 4 × 4 block, while smoothing blends edge colors.

Reproduce the result
- Load the sample or select frame-01.png from the downloads below.
- Choose 4× pixel art. Inspect Before and after, then download the PNG.
- Switch Resampling to Smooth and export again. Compare the edges at 100% zoom.
- Use whole-number scales for even pixel blocks. Fit to max dimensions only shrinks images and preserves aspect ratio.
Expected result
Two 256 × 256 PNGs with different edge treatment. The reference comparison shows nearest-neighbor on the left and smooth on the right. Browser smoothing can vary.

Frequently Asked Questions
Most editors default to smooth interpolation, which blurs pixel art. Choose Nearest-neighbor in this tool to preserve hard pixel edges, or Smooth for illustrations and photos. The 2×, 3×, and 4× pixel art presets select nearest-neighbor automatically.
Yes — batch mode applies the same target size or scale factor to every uploaded image, keeping a whole animation set consistent.
Whole-number multiples (2×, 3×, 4×) keep every source pixel an exact square block. Fractional scales force resampling and can distort the art.
Yes — author at your highest resolution, then batch-resize to 50% (and 25% if needed) for the lower-density sets. Downscaling from a clean master always beats upscaling, so keep the big version as your source of truth.
Downscale whenever possible. Upscaling can't invent detail: pixel art survives whole-multiple upscales exactly, but painted or photographic sprites go soft. If assets must ship larger than the source, consider redrawing the source bigger instead.
Odd dimensions and off-center pivots don't survive scaling cleanly — a 15px-wide sprite at 50% has no exact center. Keep source dimensions even (ideally multiples of your scale factors) so pivots and collision boxes land on whole pixels after resizing.
