Minecraft Image Converter vs PixelStacker

Minecraft Image Converter is a free web tool that turns images into block grids and build plans. It accepts PNG, JPG, JPEG, and WebP files and offers Wool, Concrete, Terracotta, and Full Blocks palettes. Dithering, brightness and contrast controls, zoom, and grid lines let users adjust the conversion. For building, it provides block counts, a copyable material list, and row-by-row guidance. Exports include PNG references and Sponge .schem v3 schematic files for WorldEdit-style workflows. A schematic represents a one-block-thick vertical wall, not a complete three-dimensional model. The palettes currently use Java Edition blocks; Bedrock compatibility is described as planned for a future update. Images are processed in the browser and, according to the maker, are not uploaded, stored, or reviewed. The privacy policy says the site may collect aggregated usage information such as page views and feature interactions, without identifying individual users. The tool is free for personal and commercial use, with no sign-up or watermark. It is an independent fan project, not affiliated with Mojang Studios or Microsoft.

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.
