6. How to Create a Bitcoin / Crypto QR Code
QR codes are the standard way to share cryptocurrency wallet addresses. They eliminate copy-paste errors and support the BIP-21 payment URI format for Bitcoin.
Steps:
1. Go to QRCodeGen.ai and select Text or URL
2. For a simple address: paste your wallet address
3. For a BIP-21 payment request: enter bitcoin:youraddress?amount=0.01&label=Payment
4. Generate and share
Why QR codes for crypto: Wallet addresses are long strings of random characters. A single wrong character sends funds to the wrong address forever. QR codes eliminate this risk.

8. How to Create a Restaurant Menu QR Code
Link your digital menu to a QR code that diners scan at their table. Update your menu online anytime without reprinting QR codes.
Steps:
1. Host your menu online (Google Docs, your website, a PDF on Google Drive, or a menu service)
2. Go to QRCodeGen.ai and select URL
3. Paste the link to your online menu
4. Customize with your restaurant's brand colors and logo
5. Print on table tents, stickers, or placards
Pro tip: Use a URL you control (like yourrestaurant.com/menu) rather than a direct Google Docs link. This way you can update the menu content without changing the QR code.

QR Code Best Practices
Design
• High contrast is essential — dark dots on a light background. Avoid light-on-light or dark-on-dark.
• Minimum size: 2cm × 2cm for print, 200×200px for screens.
• Add a call-to-action: "Scan for menu," "Scan to connect to WiFi," etc.
• Test before printing — scan with both iPhone and Android.
Privacy
• QRCodeGen.ai processes everything in your browser. Your WiFi passwords, contact info, and URLs never leave your device.
• Most other QR code generators send your data to their servers. This matters when encoding passwords or personal information.
Static vs Dynamic
• Static QR codes (what QRCodeGen.ai creates) encode data directly. They work forever, need no internet, and can't be tracked.
• Dynamic QR codes use a redirect server. They can be edited after printing but cost money, depend on the service staying online, and track every scan.
• For most use cases, static codes are the better choice. Read our full comparison.

Frequently Asked Questions
Is QRCodeGen.ai really free?
Yes — unlimited QR codes, full customization, no watermarks, no account required. It's free because it runs entirely in your browser with no server costs.
What QR code types can I create?
URL, WiFi, vCard (contact card), Email, Phone, SMS, and plain Text. Plus specialized formats like WhatsApp click-to-chat and Bitcoin payment URIs.
Can I add my logo to a QR code?
Yes. Upload any image and it's placed in the center of your QR code. QR codes have built-in error correction, so they scan reliably even with a logo covering part of the pattern.
What's the best format to download?
Use SVG for print (scales infinitely without quality loss). Use PNG for digital — screens, social media, presentations. QRCodeGen.ai supports up to 2048×2048 resolution.
Do QR codes expire?
Static QR codes never expire. The data is encoded directly in the image. As long as the image exists and the destination (URL, WiFi network, etc.) is valid, it works forever.
Are QR codes safe?
QR codes themselves are just encoded data — they're as safe as the content they point to. The privacy concern is with the *generator*: most send your data to their servers. QRCodeGen.ai eliminates this by processing everything locally. Read our privacy guide.
Can I create QR codes on my phone?
Yes. QRCodeGen.ai works on all modern mobile browsers — iPhone Safari, Android Chrome, and others. No app download needed.
