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.

What is a BIP-21 payment URI?

BIP-21 is the Bitcoin standard for payment URIs like bitcoin:address?amount=0.05&label=Shop. Most wallet apps recognise it and prefill the address, amount and label when you scan it. Ethereum uses the similar EIP-681 scheme.

Should I set an amount on the QR code?

It is optional. Adding an amount means the payer's wallet prefills it, which reduces mistakes for fixed-price payments. Leave it blank for donations or variable amounts so the payer enters their own figure.

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

This generator turns a crypto wallet address into a scannable QR code, encoded as a standard payment URI so a payer can scan it and have the address — and optionally the amount and label — prefilled in their wallet app. It supports Bitcoin, Ethereum, Litecoin and Dogecoin, plus a raw mode for any other chain. Always use your public receiving address; never a private key or seed phrase.

How it works

For a supported coin the tool builds a BIP-21 / EIP-681 style payment URI: the coin’s scheme, a colon, your address, then any optional parameters as a query string. For example bitcoin:address?amount=0.05&label=Shop. The amount and label are URL-encoded so special characters are handled correctly. In raw mode it encodes the address exactly as entered, for chains without a standard URI scheme. That string is then rendered into a QR code you can download as PNG or SVG.

Example

For a Bitcoin address with a 0.05 BTC amount and the label Coffee, the encoded payload is:

bitcoin:bc1qexampleaddress?amount=0.05&label=Coffee

When a payer scans it, their wallet opens a transaction to that address with 0.05 BTC and the “Coffee” label already filled in.

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.
