Pixel Art Scaler

Upscale pixel art and sprites without blur. Use nearest neighbor for crisp, blocky edges at 2×, 4×, 8×, or any factor, or Scale2x and Scale3x to smooth diagonals while keeping the pixels sharp. Everything happens in your browser, so nothing is uploaded.

What the pixel art scaler does

Pixel art is made of a small grid of hand-placed pixels. When you enlarge it with a normal image editor, the software blends between those pixels to fill the gaps, and the sharp, blocky look turns into a soft blur. That is the opposite of what pixel art needs.

This tool scales the image up with no blending. With nearest neighbor, each pixel becomes a solid square block, so a 4× scale turns one pixel into a clean 4 by 4 square. The edges stay hard and the colors stay flat, exactly like the original, just bigger.

If your sprite has a lot of diagonal lines, Scale2x and Scale3x go a step further. They are pixel art algorithms that round off the staircase edges while keeping everything crisp, which can look smoother than plain nearest neighbor at the same size.

Why use our pixel art scaler

  • ·Free. No signup, no watermark, no limits.
  • ·No blur. Nearest-neighbor scaling keeps every edge crisp and every color flat.
  • ·Smart algorithms. Scale2x and Scale3x round off diagonals for a smoother retro look.
  • ·Keeps transparency. Transparent sprite backgrounds stay transparent in the PNG.
  • ·Runs in your browser. Your image is never uploaded or saved.

How to use it

  1. 1

    Add your pixel art

    Drag a PNG, GIF, or WebP sprite onto the box or pick a file. It is read in your browser and never uploaded. The tool reads every pixel at its true size.

  2. 2

    Pick a scaling method

    Choose nearest neighbor for crisp, blocky upscaling at any factor, or Scale2x and Scale3x to round off diagonal edges while keeping the pixels sharp.

  3. 3

    Set the scale factor

    For nearest neighbor, pick 2×, 4×, 8×, 16×, or any factor in between. Each pixel becomes a square block that many times as wide, so nothing turns blurry.

  4. 4

    Download the PNG

    The scaled image is shown next to your original so you can check it, then saved to your device as a PNG with clean, hard edges.

Nearest neighbor vs Scale2x and Scale3x

Nearest neighbor is the classic choice. It copies each pixel into a square block, so the result is a perfect, larger copy of the original with hard edges. Use it at whole-number factors like 2×, 4×, or 8× when you want the art to look exactly the same, only bigger.

Scale2x andScale3x come from the EPX family of pixel art algorithms. They enlarge by 2× or 3× and smooth the jagged steps along diagonal lines, which can make curved sprites look cleaner. They still keep flat colors and sharp pixels, so the retro feel stays. If you are not sure, try nearest neighbor first, then switch to Scale2x to compare.

Who upscales pixel art

Anyone who works with sprites or retro art can use this to make it bigger without losing the look. These are the people who use it most:

  • ·Game developers and sprite artists. Upscale sprites and tilesets for a store page, a trailer, or a higher-resolution build without losing the crisp pixel look.
  • ·Streamers and content creators. Blow up a small pixel avatar, emote, or logo so it stays sharp on a stream overlay, a thumbnail, or a banner instead of turning fuzzy.
  • ·Anyone printing pixel art. Printers and canvases need more pixels than a tiny sprite has. Scale it up first with hard edges so each pixel prints as a clean square.
  • ·Designers placing retro art. Drop a scaled sprite into a slide, a poster, or a web page at the size you need, with none of the blur a normal resize adds.

Frequently asked questions

How do I upscale pixel art without it getting blurry?
Use nearest-neighbor scaling. A normal resize smooths between pixels, which blurs sharp art. Nearest neighbor instead turns each pixel into a solid square block, so the edges stay crisp. Add your image here, pick a scale factor, and download the result. Nothing is uploaded.
What is nearest-neighbor scaling?
It is the simplest way to enlarge an image: every source pixel is copied into a square block of the same color, with no blending. For pixel art that is exactly what you want, because it keeps the hard edges and flat colors instead of smoothing them away.
What do Scale2x and Scale3x do?
They are pixel art scaling algorithms (from the EPX family) that make an image 2× or 3× larger while rounding off jagged diagonal edges. Unlike nearest neighbor, they smooth staircase lines a little, but they keep the pixels sharp and the colors flat. Try both and pick the look you prefer.
Which scale should I use: 2x, 4x, 8x, or 16x?
Whole-number factors keep pixels perfectly square, so stick to them. Pick the smallest factor that reaches the size you need. For example, a 32 px sprite at 8× becomes 256 px. Larger factors make a bigger, sharper block but also a heavier file.
Does this work on transparent PNG sprites?
Yes. The tool keeps the alpha channel, so transparent areas of a sprite stay transparent in the scaled PNG. The result is saved as a PNG, which preserves that transparency.
Are my images private?
Yes. The whole process runs in your browser. Your image is never uploaded to a server or saved anywhere, and once the page has loaded you can even use it offline.
