Pixel Art Upscaler
Scale up pixel art with algorithms designed to preserve sharp edges and details.

Nearest Neighbor
Classic pixel-perfect scaling. Each pixel becomes a block.
Scale2x / Scale3x
Smart edge detection that smooths diagonal lines.
HQ2x
Advanced algorithm with subtle anti-aliasing.
Frequently Asked Questions
Which algorithm should I use?
Nearest: For authentic retro look.
Scale2x/3x: For promotional art or larger displays.
HQ2x: For subtle smoothing.
Why does my image look blurry?
Make sure your source image is actual pixel art (small dimensions, no anti-aliasing). These algorithms work best on crisp, low-resolution images.
What about non-integer scaling?
You can scale by any percentage. Integer scales (100%, 200%, etc.) with Nearest Neighbor preserve pixel-perfect quality. Non-integer scales may introduce some interpolation.
