Upscale
Nearest-neighbor upscale for crisp pixel art.
Scale sprites up without the AI fuzz — every pixel stays sharp.
Standard image scalers smear pixel art into soft, watercolor mush. The StudioSprite Upscaler uses pure nearest-neighbor scaling, so a 32×32 sprite scaled 4× becomes a perfectly crisp 128×128 — every pixel multiplied, none invented.
It runs entirely in your browser, handles transparency cleanly, and is built for indie devs, RPG Maker creators, and anyone shipping 2D games who needs sprites to render at a larger resolution without losing the retro feel.

Frequently asked
Why does my pixel art look blurry when I scale it in Photoshop?+
Default image scalers use bilinear or bicubic interpolation, which is designed for photos. Pixel art needs nearest-neighbor scaling — that's exactly what this tool does.
What's the maximum upscale factor?+
8× per pass. You can re-upload the result to go higher if needed.
Does it work with transparent PNGs?+
Yes — alpha is preserved exactly, so the upscaled sprite drops straight into your game with no halo or background.
Is there a file size limit?+
Processing happens in your browser, so the only limit is your device's memory. Typical sprites up to 1024×1024 work instantly.
