Head Lab

Head Lab – Custom Player Head Editor & Generator

Design, preview and grab custom player heads — entirely in-game. No websites, no commands, no permissions.

Head Lab is a client-side custom player head editor and generator for Fabric. Press K (rebindable) or run /headlab-editor to open a pixel editor, paint a custom head, watch it live in 3D, and get the finished player head straight into your inventory — in singleplayer or on any server. It's an in-game replacement for online head generators and skin-to-head websites.

Features

• Pixel editor — paint all 6 faces on an unfolded net, base + hat layers, with pencil, eraser, fill and color picker. Undo/redo, mirror mode, and tool hotkeys.
• Live 3D preview — rotate, auto-rotate, and a head or full-body view.
• Full color control — 32-color palette, HSV picker, alpha bar for shading, hex input, and recent colors.
• Skin import — load any player's skin as a head by nickname (from the server itself, with autocomplete), or one-click your own skin.
• No permissions needed — in creative the head is delivered via the vanilla creative packet, so it works on any server without OP, plugins or commands.
• Load existing heads — open the editor holding a head to edit it, or paste a Value / URL / hash.

How to use

1. Press K (or /headlab-editor) to open. Holding a head loads it automatically.
2. Start from New, My skin, a player's skin (Load), or the head in your Hand.
3. Paint on the unfolded net — pick a tool (B/E/G/I) and a color, switch base/hat with Tab, mirror with M, undo with Ctrl+Z.
4. Check the live 3D preview — drag to rotate or switch to full-body view.
5. Press Generate — in creative the head drops straight into your inventory.

Generating uploads your drawing to MineSkin for a Mojang-signed texture. An optional API key gives faster limits — set it with the API Key… button or in config/headlab.properties.

FAQ

Does the server need the mod? No — everything except the optional /headlab give command is client-side.

Do I need OP/permissions? No. Creative delivery uses the vanilla inventory packet.

Why does Generate need internet? Head textures must be signed by Mojang; MineSkin does that.

Which versions? Minecraft 1.20.2 – 1.20.4 with Fabric Loader ≥ 0.16 and Fabric API.
