GenQR AI
Your 100% Free QR Code Generator

Accepting cryptocurrency payments is easier with QR codes. Our qr code generator free lets you create qr code free for Bitcoin, Ethereum, and other cryptocurrencies in seconds.

Bitcoin URI Scheme

Bitcoin QR codes use the BIP-21 URI scheme:

bitcoin:1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa?amount=0.001&label=MyStore&message=Order%20%2312345

• bitcoin: — Protocol identifier
• address — Receiving wallet address (required)
• amount — BTC amount (optional, decimal)
• label — Human-readable label for wallet display
• message — Transaction description

How to Generate a Bitcoin QR Code

1. Select "Bitcoin" tab in our qr code generator
2. Paste your Bitcoin address (starts with 1, 3, or bc1)
3. Optional: Enter amount in BTC (e.g., 0.005)
4. Optional: Add label (your business name)
5. Optional: Add message (order ID, invoice number)
6. Customize design if desired
7. Download as SVG for print, PNG for digital

Supported Cryptocurrencies

Our qr code free generator supports multiple crypto URIs:

• Bitcoin (BTC): bitcoin:address
• Ethereum (ETH): ethereum:address (EIP-681)
• Litecoin (LTC): litecoin:address
• Bitcoin Cash (BCH): bitcoincash:address
• Dogecoin (DOGE): dogecoin:address
• Generic: Any URI scheme your wallet supports

Amount Handling

Fixed amount: Include amount= parameter. Wallet pre-fills the amount — user just confirms.

Variable amount: Omit amount parameter. User enters amount in their wallet — ideal for donations, tips, or variable invoices.

Design Tips for Crypto QR Codes

• Use Bitcoin orange (#F7931A) or Ethereum blue (#627EEA) for modules
• Add crypto logo in center (auto-background-removal)
• Error correction Level H — crypto addresses are long, creating dense codes
• Download SVG for crisp display at any size

Security Considerations

• Verify address: Always double-check the address in the QR code matches your wallet
• Test first: Scan with your own wallet before publishing — send a dust amount (0.00001 BTC)
• Static codes = static addresses: If you rotate addresses for privacy, generate new QR codes
• No amount = user enters: Risk of typos; consider fixed amounts for commerce

Use Cases

Merchant Payments

Print Bitcoin QR code on invoices, receipts, or POS displays. Customers scan and pay instantly.
