Quarry documentation

Quarry is a browser-based editor for Minecraft Bedrock worlds. It runs entirely in your browser — nothing is uploaded to a server. Import a world, edit it in a 3D viewport, and export it back out, ready to play.

Quarry is an unofficial tool. It is not affiliated with or endorsed by Mojang Studios or Microsoft.

Getting started

1. Open a world. On the welcome screen, import a .mcworld file or a world folder, or start a fresh world from a template — Flat, Creative platform (a clean slab in the void), or Empty — which starts you on a build plane, a virtual grid floor to place that first block on. You can also restore your most recent autosaved session. First time in? Hit Take a tour for a quick guided walkthrough (replayable from the ☰ menu).
2. Look around. Hold the right mouse button and drag to look; WASD to fly; scroll to zoom. (Full list under Controls.)
3. Pick a block. Use the hotbar along the bottom — click a slot, scroll over it, or press number keys 1–9. Open the palette to browse and search every block, including any add-on blocks in the world.
4. Build. Choose a tool from the left column (build, brush, shape, line, fill, select…) and click in the world. See Building tools.
5. Export. When you're done, use Export to download an updated .mcworld. Quarry also autosaves locally as you work, so a reload won't lose progress.

The interface

The tool column on the left selects what a click does. The active tool's settings live in the options bar across the top (directly under the top bar) — its controls sit inline, anything extra is behind the ⋯ button, and multi-step tools put their Apply / Cancel buttons at the bar's right end. Editing panels (Selection, Mask, Inspect, Library…) are sections of the dock on the right edge — one open at a time, switched by its icon tabs. Most tools show a live preview before you commit.

Good to know

• Your edits are non-destructive. Quarry only rewrites the parts of the world you actually change; everything else (entities, biomes, player data, unfamiliar data) is preserved exactly.
• The layout adapts to your screen. Laptops get a tightened compact layout; on big monitors (1920px and wider) the right dock widens and the block picker shows four columns. No settings to flip — it follows the window size.
• Exports target Bedrock 1.20.60+ (chunk version 40). Very old pre-1.13 chunks are preserved on export but not shown in the viewport.
• Different dimensions have different height ranges — Overworld −64…320, Nether 0…128, End 0…256.
• Pick a UI theme from the ☰ menu — Auto (matches your system), Dark, Light, Midnight, Minecraft, or High contrast. It restyles the editor interface only; the world rendering is unaffected.
• Blocks render from accurate Minecraft models. Quarry draws each block from its real Java model geometry (painted with Bedrock textures), so shapes like stairs, fences, rails, doors and lecterns match the game exactly, with connected blocks, biome tinting and Vibrant Visuals all intact. To fall back to the simpler built-in shape renderer, untick Accurate block models in the ☰ menu.
