Bloxelizer vs SchemViewer

Bloxelizer provides Minecraft schematics and building tools for browsing builds, viewing them in 3D, following guides, and converting files. Its free toolkit includes an image and 3D-model voxelizer, a pixelizer for pixel art and map art, and a converter. The converter handles Minecraft schematic and world formats, Hytale prefabs, 3D models, and images; it also supports world imports and batch processing. Conversion runs in the browser without uploading files unless you choose to save or share them. If a target Minecraft edition or version lacks a block, Bloxelizer maps it to the closest available block. The free plan requires no account. Plus adds guide exports, texture packs, modded blocks, private schematics, progress tracking, teams, and bulk conversion. Plus (monthly) is $2.50 a month; Plus (yearly) is $29.99 a year. Creator plans add further tools for managing and presenting builds. Available platforms are listed as web, and an install guide covers adding it to mobile home screens.

SchemViewer is a free browser-based 3D viewer for Minecraft .litematic schematic files. It uses the Deepslate WebGL engine for interactive viewing, with controls to rotate, zoom and pan. A Y-axis slicer changes the visible height to inspect schematic layers, while region controls show or hide individual subregions and their bounding boxes. The searchable materials checklist supports filtering and checking off blocks. Technical mode switches between default Minecraft textures and customized technical textures. Users can export block lists and metadata as CSV or JSON; the placement workflow is export-only. The maker says files are processed offline in the browser and are not uploaded to a server. A Canvas 2D renderer provides a fallback to the WebGL viewer. The listed format is .litematic, and listed platforms include web, Linux, macOS and Windows. The project is licensed under MIT. For local use, the README describes cloning the repository and opening index.html in a web browser.
