What Pixel Art Upscaler does

Resize pixel art in most editors and it comes out soft, because they smooth by default. The Pixel Art Upscaler resizes by nearest neighbour and whole numbers only, 2x to 16x, so every pixel becomes a sharp square block and no pixel ends up wider than its neighbour, which is what a 1.5x resize does.

Drop one sprite, a whole sheet or a folder. A sheet's data comes along: JSON atlases, Tiled tilesets and Godot 4 .tres files get their frame positions and sizes scaled by the same number, so the frames still line up. The page shows smooth against crisp side by side, and it can spot art that was already scaled up and shrink it to its real pixels first.

How it works

  1. Drop a sprite, a sheet or a folder on the box (or try our sample).
  2. Pick a scale from 2x to 16x and compare smooth against crisp.
  3. Add the sheet's .json or .tres if you have one; it is scaled with the picture.
  4. Download the PNG, or a ZIP for several files.

What you get out

  • PNG at 2x to 16x
  • ZIP for many files or a folder
  • Scaled JSON atlases, Tiled tilesets and Godot .tres
