Pixel Art Scaler — Upscale Sprites with Crisp Edges

Upload pixel art to scale up

Accepted formats: JPG, PNG, WEBP, BMP, GIF (non-animated)

Upload Image

Paste (Ctrl/⌘+V) or drop an image — or import from a URL

Upscale pixel art and game sprites by an exact 2× to 8× without the blurry softening that ordinary resizing causes. Nearest-neighbour keeps every pixel hard and blocky, while the EPX/Scale2x and Scale3x algorithms smooth diagonals and curves while keeping your palette pixel-exact. Everything runs in your browser — nothing is uploaded.

Frequently Asked Questions

How do I enlarge pixel art without it becoming blurry?

Use the nearest-neighbour mode. It multiplies each pixel into a clean block, so a sprite scaled 4× stays perfectly crisp instead of being smoothed into a fuzzy mess like a normal photo resize would do.

What are Scale2x and EPX?

Scale2x (also called EPX) and Scale3x are pixel-art upscaling algorithms that intelligently smooth diagonal lines and curves while preserving the original palette. They make sprites look hand-drawn at a larger size without introducing new colors.

Does upscaling change my sprite's colors?

No. Every mode keeps the palette exact — no new colors or anti-aliasing are introduced. This matters for retro art where a precise, limited palette is part of the style.

Is the pixel art uploaded anywhere?

No. The scaling is computed entirely in your browser, so your sprites and tiles never leave your device.
