What it is

PixelStacker turns an input image into multilayer Minecraft pixel art by matching image colors to combinations of accepted in-game materials. It builds additional blending and color options by stacking stained glass over other blocks. Double layer mode combines stained glass panels with newer Minecraft blocks to broaden the palette. The program provides viewing options for building the result in-game and can save PNG or Schematic files. Listed export formats also include schem, NBT, schem3, and a materials list, with custom palette control. PixelStacker has a web demo and an API, as well as downloadable desktop releases in its GitHub repository. Listed platforms are web, Windows, and API. The maker says image handling can reach 8k, depending on the computer's specifications. Taylor Love is identified as the author and developer, and describes the project as a proof of concept for creating pixel art to build in-game. PixelStacker is free and open source; no paid plans or usage limits are stated.
