ItemSeed — Pixel Art RPG Item Generator

ItemSeed is a seeded, deterministic procedural pixel-art RPG item generator that runs directly in your browser.

Generate infinite weapons, gear, and magical artifacts without external dependencies or heavy engines. Every generated asset can be downloaded as a clean, transparent PNG and is licensed under CC0 1.0 Universal — 100% free for commercial and indie games with no strings attached.

✨ Key Features

• Native 16×16 & 32×32 Pixel Art: Built from the ground up for retro resolutions. 16×16 icons are uniquely hand-compressed with feature-folding logic, never crudely downscaled.
• Same Seed = Same Item: Fully deterministic procedural generation. A 20-character string reproduces the exact same sprite every time, allowing artwork to live in source code rather than binary blobs.
• 24-Cell Batch Exploration: Explore 24 procedural variations simultaneously. Click any cell to immediately inspect, fine-tune, or download.
• Transparent PNG Export: Single-click download (⇩ png) with standardized filenames containing item type, seed string, and resolution.
• Multi-Theme & Multi-Language: Seamless dark/light theme switching and full dual-language support (English & 繁體中文).
• Runs Everywhere: Zero build step, vanilla HTML5 Canvas + JavaScript. No ads, no logins, no paywalls.

🛡️ Supported Item Families

1. Potion: Volumetric flasks, round bottles, test tubes with fluid levels, bubbling effects, and cork/wax/cloth seal stoppers.
2. Sword: Slanted broadswords, rapiers, and curved sabers with blade reflections, crossguards, grips, and pommels.
3. Spear: Symmetrical tridents, harpoons, and straight lances with bound shafts and butt caps.
