Arachne

What Arachne is

Arachne is a free, open-source web tool for turning pictures into Minecraft map-art schematics for survival or creative building. Designs can be flat or staircased and range from one map to a 16×16 grid. It estimates the effort to build and remove each block choice, accounting for tool tier, Efficiency, Silk Touch, haste, flying, and whether the block drops itself when broken.

For image rendering, Arachne provides error-diffusion methods, ordered patterns, palette color mixing, and an optional pass to refine results for viewing distance. Text can be added using 142 site-served fonts, with effects including outlines, shadows, underlines, gradients, rotation, and mirroring. The tool counts art, filler, and noobline blocks, and provides a searchable filler-block list that accounts for game versions.

Arachne targets Minecraft releases from 1.13 through the current release, with the palette and file DataVersion following the selected version. It exports Litematica .litematic files, vanilla structure .nbt files readable by Litematica and WorldEdit, optional map data files, and a plain-text build sheet. The maker says images stay in the browser and presets are stored there; the site has no backend, analytics, or tracking, though the server keeps ordinary security request logs. Arachne is in beta, and its source is licensed under GPL-3.0-only.

Who it suits

Arachne suits Minecraft builders who want to convert images into map art and plan the materials and effort involved. It is useful for people creating flat or staircased designs, adding text, and exporting schematics for Litematica or WorldEdit.

Getting started

1. Visit the Arachne website in a web browser.
2. Choose a Minecraft release from 1.13 through the current release.
3. Create a flat or staircased layout, from one map up to a 16×16 grid.
4. Use the image rendering options and add text if needed.
5. Review block counts and estimated building or removal costs.
6. Export a Litematica schematic, vanilla structure file, optional map data, or text build sheet.

Verdict

Choose Arachne if you want a free, open-source way to turn pictures into Minecraft map-art schematics and plan materials. Its export formats and block estimates support both design and building preparation. Look elsewhere if you need a product outside the web or require a release that is not in beta.
