About QR Code Generator
Error correction is the setting worth understanding: higher levels rebuild a code that is partly obscured or scuffed, at the cost of a denser pattern. Raise it for anything printed on a label that will take wear, keep it low for clean on-screen display.
Encode your name, phone, email and company into a vCard QR code that drops your full contact card into any phone with one scan. It is generated on your device, so your details stay private.
Generate scannable QR codes for links, WiFi networks, contact cards (vCard), SMS messages and email, then fine-tune the size, foreground and background colours and error-correction level before exporting a crisp PNG or vector SVG. A WiFi QR lets guests join your network with one scan; a vCard QR drops your contact details straight into a phone; a URL QR bridges print and web.
Higher error-correction levels add redundancy so a code still scans when part of it is dirty, printed small or covered by a logo. The image also encodes your value directly rather than pointing at a shortener, so it keeps working indefinitely — there is no redirect to expire, break or start charging.
