When should you use QR Code Generator vs other tools?
Use QR Code Generator when the goal is fast scanning and sharing. If the linked asset is an image that still needs format cleanup before you encode it, continue with Image Convert. If you are building a broader asset workflow around uploads, graphics, and exports, jump to the Image Tools hub.
No-upload workflow: your QR text, Wi‑Fi credentials, payment links, and scanned images stay in the browser instead of being sent to a third-party QR service.
Frequently Asked Questions
What can I encode in a QR code?
QR codes can encode URLs, plain text, email addresses (mailto:), phone numbers (tel:), SMS messages, WiFi network credentials, geographic coordinates, and vCard contact information.
What is error correction level?
QR codes have built-in error correction allowing them to be read even if partially damaged. Level L (7%), M (15%), Q (25%), H (30%). Use H if you plan to overlay a logo on the QR code.
How large should I print a QR code?
Print QR codes at least 2cm × 2cm. As a rule of thumb, the scanning distance should be at most 10× the QR code size.
Can I use this for Wi-Fi, menus, payment links, or internal handoff pages?
Yes. Those are some of the most practical use cases. QR codes work well for Wi-Fi sharing, table menus, print signage, payment links, app downloads, and cross-device handoff flows.
Is my data sent to a server when generating?
No. QR code generation and scanning both happen locally in your browser. Your URLs and content are never transmitted to any server.
Can I create QR codes for Wi‑Fi, menu links, or payment pages?
Yes. These are some of the most common workflows. You can generate QR codes for Wi‑Fi credentials, restaurant menus, payment URLs, contact cards, and event links, then download them for print or digital sharing.
