MC-Web launcher
Minecraft Java 26.2 in the browser, built from your own game files. Do the steps in order; steps 1 and 2 are only needed once per browser.
1. Choose a player name
3–16 letters, numbers or underscores. Worlds are saved in this browser under this name. There's no sign-in.
Player: choose a name.
2. Get the game
Click LOAD GAME FILE and pick your .mcweb game file.
Game: not loaded yet.
Your worlds (optional)
YOUR WORLDS (IMPORT / EXPORT .ZIP)
Export a world saved in this browser as a .zip, to back it up or move it to another device. Import works with any Java Edition 26.2 world .zip.
3. Play
Opens fullscreen. Click the game once to capture the mouse. Stay in fullscreen: in a normal window Ctrl+W closes the tab and loses anything unsaved. Hold Esc to leave fullscreen.
Chromebook detected: turn this on if you are playing on the touchpad.
In the world, the R key is right-click: tap R to place blocks and use items, hold R to eat, draw a bow or block with a shield. Clicking the touchpad stays left-click (break blocks, attack). A two-finger tap on the touchpad also right-clicks.
Drop a resource-pack .zip or folder here.
Packs stay in this browser. Turn them on from Options → Resource Packs in the game.
MORE (remove install, boot diagnostics)
Renderer: WebGPU when the browser has it, otherwise WebGL2 (Chromebooks). Add ?mcweb_gl=webgl2 to the address to force WebGL2.
Local server: connecting.
Multiplayer: set your Friends status to Joinable while in a world, and friends can press Join.
