LifeSimGrid: Your Ultimate Toolkit for Life Simulation Games

LifeSimGrid offers a suite of powerful, 100% client-side tools designed to enhance your experience with life simulation games like Animal Crossing and Tomodachi Life. Our mission is to provide a comprehensive, privacy-first utility suite for sandbox life sim players and retro 8-bit enthusiasts. All tools operate entirely on open, universal web standards, requiring no software downloads, no account registrations, and no cloud server reliance.

Core Features:

• ACNH Pixel Studio: Convert any image into Animal Crossing custom design pixel patterns and Tomodachi Life pixel art. Features smart scaling, multi-ratio support (1:1, 2:3, 16:9), four grid density levels (32×32 to 256×256), adjustable brightness and contrast, and an optional 32-color 8-bit retro palette. The paint-by-numbers system with numbered color swatches acts as a perfect tracing guide for in-game editors.
• Mii QR Code Unlocker: Instantly fix 'This Mii Cannot be Edited' errors. Upload Mii QR codes to unlock copying and editing permissions. Supports single-file editing and batch processing for multiple QR codes, exporting unlocked Miis as individual PNGs or a single ZIP file. Processes FFL binary data locally without server interaction.
• Tomodachi Voice Lab (MBTI): Synthesize 8-bit Mii voices for Tomodachi Life using the Web Audio API. Choose from 5 retro voice presets (Adult Male, Adult Female, Elder, Child, Robot), customize pitch and speed, and test custom phrases with the text-to-speech simulator. Explore the 16-personality MBTI-style compatibility calculator and relationship leaderboard.
• Pixel Grid Studio: A general-purpose image-to-pixel-art converter for various crafting and gaming projects. Supports custom grid sizes from 16×16 to 128×128, with features like error-diffusion dithering and Euclidean distance color matching.
• Tomodachi Island Planner: Design your Tomodachi Life island layout with an interactive grid planner. Drag and drop buildings, place residents by MBTI compatibility, and export your island design as a template (PNG or JSON).

Privacy-First Engineering:

Every tool on LifeSimGrid runs entirely in your browser. No images, QR codes, or game data are ever uploaded to any server. Your data stays on your device — always. All processing happens client-side using HTML5 Canvas, Web Audio API, and binary data parsing. No account is required to use any tool, ensuring instant access and zero tracking.

Open Source Commitment:

The full source code for LifeSimGrid is publicly available on GitHub under the MIT License, allowing for community audit and contributions. We are committed to transparent, open-source software development.
