mc-pixel vs PixelStacker

mc-pixel is a free web creator that turns images into Minecraft block-art schematics for Minecraft Java Edition. It accepts PNG, JPG, WebP, and GIF files and exports .litematic schematics, with CSV also listed as an export format. Users can configure horizontal floor art or vertical wall art and adjust dimensions up to the displayed total limit of 16,384 blocks. Its palette lists Wool, Concrete, and Terracotta among 49 available blocks. Designs can be viewed as a 2D pixel grid or 3D block preview, and the creator includes undo and a materials list. Users can tune palette categories, fill empty pixels, and add a foundation layer. Accounts can save, edit, or delete creations and set them public or private. The community gallery supports tag filtering, previews, and downloads of published schematics. Public creations have shareable pages showing a preview, size, author, and download. The exported .litematic file is described as ready for the Litematica mod.

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.
