Bitcoin QR Code Generator: Create Free BTC Payment QR Codes
By Aniket Nigam · Verified 2026-04-15 · Methodology
Quick Answer
A Bitcoin QR code uses the BIP-21 payment URI format: bitcoin:{address}?amount={BTC}&label={merchant}. Scanning opens the user's Bitcoin wallet with the address and amount pre-filled, reducing the chance of a copy-paste error on a 34-character address.

Frequently Asked Questions
Does the Bitcoin QR work with all wallet apps?
All major Bitcoin wallets support BIP-21 URI format: Coinbase Wallet, Trust Wallet, Electrum, Muun, Phoenix, BlueWallet, and Bitcoin.com Wallet all scan and pre-fill the fields correctly.
Is it safe to display my Bitcoin address publicly?
Your Bitcoin address is public by design - sharing it only lets others send you funds, not access your wallet. The private key (held by your wallet) is what controls spending. Each address-QR pair is safe to display.
Should I use a new Bitcoin address for each payment?
For privacy, yes. Reusing addresses links transactions on the public blockchain, making it easier for third parties to track payment history. Most HD wallets generate a fresh address automatically after each use.
Can I encode ETH or other coins in the same format?
No. Each cryptocurrency has its own URI scheme. Ethereum uses ethereum:{address}?value={wei}. Creating a QR with the wrong scheme causes the wallet to reject or misread the payment.
