Tip: right-click any spot on Google Maps and copy the coordinates
A red Swiss flag is automatically overlaid on the QR — required by Swiss banks.
Paste a BOLT11 invoice (lnbc...) or a Lightning address. We prefix with the lightning: URI scheme so any Lightning wallet can scan it.
Compatible with Google Authenticator, Authy, 1Password, Bitwarden, and any standard TOTP app.
Encodes the entire authorized_keys line. Scan to copy/paste the key onto a new machine.
For very long keys, use rMQR landscape or split into multiple QRs. Standard QR caps around ~2KB.
The official WireGuard mobile apps scan these directly. Never include your private key in a printed QR — only digital sharing.
GS1 Digital Link is the modern web-friendly alternative to the EAN-13 barcode for retail products. Resolver domain defaults to id.gs1.org but you can use your own.
Paste the share link from the Spotify app, or just the ID. We build the open.spotify.com URL automatically.
Format depends on platform — for Mastodon use @user@instance, for Bluesky use handle.bsky.social, for Nostr paste the npub key.
Geo URI (RFC 5870) opens directly in any maps app on the device — Google Maps, Apple Maps, OsmAnd, etc. — without picking a vendor.
Standard BitTorrent magnet link. Scanned by any BitTorrent client that supports URI scheme handlers.
Paste a full RFC 5545 iCalendar payload — supports multiple events, alarms, recurring rules. Most calendar apps import the QR directly.
Local uploads stay in your browser and only appear on the printed card. MeCard QR data has no photo field.
MeCard is a simpler alternative to vCard, preferred by some Android devices

Micro QR capacity: 35 digits, 21 uppercase alphanumeric, or ~15 bytes (lowercase/URLs). Best for short codes, serial numbers, and IDs. For URLs, use standard QR instead.
Rectangular Micro QR — a narrow, wide format ideal for test tubes, wristbands, and ticket strips. Up to 361 characters.

Renders behind the QR at reduced opacity. Auto-forces EC=H so the QR still scans through the photo.
Batch Generation
Upload a CSV to generate up to 500 QR codes in a single batch. Each row becomes its own QR — pick a template or override 21 properties on a per-row basis: colors, frames, dot/eye/eyeball styles, gradients, transparency, size, error correction, format, built-in logo, and more.
21 columns: type, data, filename, frametext, frame, template, fgcolor, bgcolor, size, ec, dotstyle, eyestyle, format, logo, gradient, g2, gtype, gangle, transparent, eyeball, eyecolor. Only type and data are required. Use | to separate fields inside data (e.g. ssid|password|WPA).
All 20 QR types supported, including URL, WiFi, vCard, MeCard, Email, SMS, Event, Location, UPI, SEPA, PayPal, Crypto, Micro QR and rMQR. Download the sample CSV to see every column, all 40 templates, 11 frame styles, and the 12 built-in logos in action.
Save the entire QR — type, all field values, style, frame, logo, business card design — as a single .qr.json file. Load it later to recreate everything in one click.

How Crypto QR Codes Work
Cryptocurrency QR codes encode your wallet address in a standard URI format recognized by wallet apps. For Bitcoin, this is BIP21 (bitcoin:address?amount=X). For Ethereum, it's EIP-681 (ethereum:address). When someone scans the QR code with their crypto wallet, it pre-fills the recipient address, amount, and label — reducing errors from manual address entry.
We support four cryptocurrencies: Bitcoin (BTC), Ethereum (ETH), Litecoin (LTC), and Bitcoin Cash (BCH). Each uses the standard URI format recognized by major wallets like MetaMask, Trust Wallet, Coinbase Wallet, and others.
How to Create a Crypto QR Code
- Select your cryptocurrency — Bitcoin, Ethereum, Litecoin, or Bitcoin Cash.
- Paste your wallet address — the receiving address for payments.
- Set amount and label (optional) — pre-fill a specific amount and a human-readable label like "Donation" or "Invoice #123".
- Download your QR code and share it for receiving payments.
Where to Use Crypto QR Codes
- Accepting payments — at physical locations that accept cryptocurrency
- Donations — open-source projects, charities, and content creators accepting crypto
- Invoices — include a QR code on invoices for crypto-paying clients
- Point of sale — retail checkout screens for crypto payments
- Tip jars — digital tip jars for streamers, artists, and performers
Security Note
Always double-check your wallet address before generating the QR code. Cryptocurrency transactions are irreversible. Test with a small amount first if using the QR code for payments. Your wallet address is encoded in the QR image and is never sent to our servers.
Frequently Asked Questions
Which cryptocurrencies are supported?
We support Bitcoin (BTC), Ethereum (ETH), Litecoin (LTC), and Bitcoin Cash (BCH). Each uses the standard URI format (BIP21 for Bitcoin, EIP-681 for Ethereum) recognized by all major wallet apps.
Will any Bitcoin wallet app recognize this QR code?
Yes. The QR code uses the standard bitcoin: URI format (BIP21), which is supported by virtually every Bitcoin wallet including Coinbase, Trust Wallet, MetaMask, Electrum, BlueWallet, and others.
Can I set a specific payment amount?
Yes. Enter an amount in the optional field and it will be encoded in the QR code. The sender's wallet will pre-fill the amount. They can still modify it before sending if they choose.
What if I send to a wrong address — can it be reversed?
No. Cryptocurrency transactions are irreversible by design. Once a transaction is broadcast and confirmed, there is no central authority that can claw it back. Always double-check the address on screen against the address on the QR code (or rescan it). For new payment flows, test with a small amount first.
Does the QR code work for SegWit and Taproot addresses?
Yes — the bitcoin: URI format works with any valid Bitcoin address type: legacy (1...), P2SH (3...), bech32 SegWit (bc1q...), and Taproot (bc1p...). Just paste the address you want to receive at — the QR code encodes it verbatim. Modern wallets handle all four address types correctly.
Can I include a payment label or note?
Yes. The optional 'Label' field encodes a human-readable description (e.g., 'Donation', 'Invoice 2026-001') as a URL parameter. The sender's wallet displays it before they confirm the payment, which helps them recognize what they're paying for. Keep labels short — under 50 characters — for the cleanest QR code.
Is the wallet address visible to anyone who scans?
Yes — the address is plain text inside the QR code, and that's by design. Bitcoin addresses are public information; sharing one is how you receive payments. Sharing your address doesn't expose your wallet, balance, or transaction history (unless someone analyses the public blockchain). For privacy, generate a fresh address for each payment.
What is BIP21 and why does it matter?
BIP21 (Bitcoin Improvement Proposal 21) is the standard for encoding payment requests in URIs like bitcoin:address?amount=0.001&label=Coffee. Every major wallet implements BIP21, so a QR code following this format works everywhere. Our generator emits BIP21-compliant URIs for Bitcoin and Litecoin/BCH, and the equivalent EIP-681 format for Ethereum.
