Secure QR Code Generator
Why Client-Side QR Codes?
Using standard online QR generators sends your input data directly to third-party tracking servers. If you are generating a QR code for a sensitive cryptocurrency wallet address or private URL, this exposes your data. This tool runs 100% locally in your browser — your text inputs and wallet keys never leave your machine.
Cryptocurrency URI Schemas
To ensure wallet apps recognize your address correctly, they use standardized URI formats:
- Bitcoin:
bitcoin:[address]?amount=[val] - Ethereum:
ethereum:[address]
