What Is a Crypto QR Code?
Crypto QR Code Generator is a free online tool that generate payment QR codes for Bitcoin, Ethereum, Solana, and more with BIP21/EIP-681 URIs. No files are uploaded — everything is processed locally on your device.
A crypto QR code generator creates scannable payment QR codes that encode a cryptocurrency address and optional amount using standard URI formats like BIP21 for Bitcoin and EIP-681 for Ethereum. These QR codes make it easy to receive payments — the sender simply scans the code with their wallet app instead of manually copying a long address. This eliminates typos and speeds up transactions for merchants, freelancers, and anyone accepting crypto payments. Our generator supports multiple coins, custom amounts, and downloadable PNG images, with your address never leaving your browser.
Privacy guarantee: Crypto QR Code Generator processes all files directly in your browser using WebAssembly. No data is uploaded to any server, no information is collected, and the tool works offline after loading. Unlimited usage with no signup, no watermarks, and no file size limits.

Frequently Asked Questions
What coins are supported?
The generator supports Bitcoin, Ethereum, and other popular cryptocurrencies. Each uses its standard payment URI format so the QR code works correctly with any compatible wallet app.
Can I add a payment amount to the QR code?
Yes. You can specify an amount that gets encoded into the QR code URI. When scanned, the sender's wallet automatically fills in the amount, reducing friction and errors.
What format does the QR code use?
Bitcoin QR codes use the BIP21 URI format (bitcoin:address?amount=X) and Ethereum uses EIP-681. These are industry-standard formats recognized by virtually all modern wallet applications.
Is my address kept private?
Yes. The QR code is generated entirely in your browser using JavaScript. Your cryptocurrency address is never sent to any server during the generation or download process.
