Which wallet formats does this support?

It builds standard payment URIs (such as bitcoin:address?amount=…) for Bitcoin, Ethereum, Litecoin and Dogecoin, plus a raw mode that encodes any address verbatim for other chains.

Is it safe to put my receiving address in a QR code?

Yes — a receiving address is public information meant to be shared. Never put a private key or seed phrase into any QR generator.

Is my address uploaded anywhere?

No. The payment URI and QR code are generated entirely in your browser; nothing is sent to a server.

Crypto Address QR Code Generator

A scannable QR code for your crypto wallet

This generator encodes a wallet address into a standard payment URI — for example bitcoin:address?amount=0.05 — so a payer can scan and have the amount prefilled in their wallet app. Choose a supported coin, or use raw mode to encode any address for any chain.

Paste your public receiving address, optionally set an amount and label, then download the code as PNG or SVG. Everything runs in your browser, so your address never leaves your device. Never enter a private key or seed phrase.
