EMG - NFT Metadata Builder

Create, edit, and export NFT metadata for multiple blockchains.

No accounts, no servers, no data collection. Your projects are stored locally and never leave your device.

Get Started

Create your first NFT metadata project. Upload images, customize metadata, and export in formats compatible with your chosen blockchain.

All data stays in your browser. No servers, no tracking, complete privacy.

Upload JPG, PNG, GIF, or WebP. Images are stored locally in your browser.

Export projects as JSON or ZIP. Import anytime to continue working.

Edit metadata across multiple NFTs at once. Save time with bulk updates.

How It Works

Choose your blockchain (Ethereum, Solana, Polygon, XRP, or Tezos) and set up your collection details.

Drag and drop your NFT images. They're stored locally in your browser using IndexedDB.

Customize names, descriptions, and attributes for each NFT. Use batch edit to update multiple items at once.

Export as JSON files, ZIP archives, or upload directly to IPFS. All metadata follows blockchain-specific standards.
