Player Guide & How to Play

Everything you need to know about playing Eaglercraft in your web browser, backing up worlds, and tweaking performance.

1 How Browser Minecraft Works

Eaglercraft is an ahead-of-time (AOT) transpiled version of Minecraft compiled to execute directly inside modern web browsers without Java or third-party desktop installers:

  • TeaVM & WebAssembly (WASM): Translates original Java bytecode into efficient WebAssembly binary code and optimized JavaScript.
  • WebGL Graphics: Converts desktop OpenGL graphics calls into WebGL 2.0 shaders to render 3D voxels at 60+ FPS on standard GPUs.
  • Sandboxed Browser Storage: Saves player preferences, keybindings, and custom skins directly on your computer.

2 Saving & Backing Up Worlds (.epk files)

Singleplayer worlds persist locally in your browser. To protect your builds from accidental browser cache clearing, export regular backups:

How to create a world backup:
  1. Open the Singleplayer world selection menu.
  2. Select your world and click Backup / Export.
  3. Save the resulting .epk file to your computer or cloud storage.
  4. To restore anytime, click Import World and choose your saved .epk backup.

3 Chromebook & Low-End Hardware FPS Tweaks

If you are playing on a school Chromebook or low-spec laptop, adjust these video settings for maximum frame rate:

  • Render Distance: Set to 4 Chunks or 6 Chunks.
  • Graphics: Change from Fancy to Fast.
  • Smooth Lighting: Turn OFF.
  • Particles: Set to Minimal or Decreased.
  • Max Framerate: Set to 60 FPS or VSync to prevent CPU thermal throttling.

4 Connecting to Community Servers & SMPs

Because browsers cannot open raw TCP sockets, Eaglercraft uses secure WebSockets (wss://). For modern versions like Eaglercraft 26.2, servers use modern proxies (such as BungeeCord or Velocity with ViaVersion).

  • Check out our curated list of 26.2 compatible servers on the Community Servers tab.
  • Copy the wss:// address (e.g. wss://tuff.ws).
  • Go to Multiplayer → Direct Connect in the game, paste the address, and click Join Server!

5 Uploading Custom Skins

Custom player skins can be loaded directly from your device without needing a Mojang account:

  • Go to Options → Edit Skin in the main menu.
  • Click Upload Skin and select any PNG skin image.
  • Both classic 64x32 format and modern 64x64 double-layer skins are fully supported.
