MinecraftArt.org Pixel Art Generator vs PixelStacker

MinecraftArt.org Pixel Art Generator converts images into Minecraft block pixel art for editing and export. It runs on the web, requires no registration, and accepts JPG, PNG, GIF, BMP, and WEBP files up to 10MB. Users can choose all blocks, survival-only blocks, or a custom palette, then adjust block selection and dithering for a Minecraft version, game mode, and block preferences. The editor includes pencil, brush, bucket fill, eyedropper, zoom, and unlimited undo and redo. Its RGB matching compares image pixels with a database of more than 1,000 Minecraft blocks. Finished designs can be exported as command blocks, .mcfunction files, or WorldEdit-compatible .schematic files; the site also describes compatibility with MCEdit and other building tools. Minecraft support is listed for versions 1.9 to 1.21. Height limits are 256 blocks before Minecraft 1.18 and 384 blocks in 1.18 or later. Image processing happens locally in the browser, and the site says it does not store uploaded images or generated files on its servers. The free service has no service-level agreement and may change or discontinue features.

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.
