QR codes are the fastest way to share a link, connect to WiFi, or save contact details without anyone having to type anything. Creating a QR code used to require special software — now it takes 10 seconds and is completely free.
What Can a QR Code Contain?
A QR code can store many types of data: Website URL (share any link instantly) | Plain text (short messages, codes) | WiFi credentials (SSID, password, encryption type) | Email (pre-filled recipient, subject, body) | Phone number (tap to call) | vCard (digital business card with name, phone, email, company) | Location (GPS coordinates for maps).

WiFi QR Code — Share Your Password Without Saying It
The most popular QR code use at home and in cafés. Create a WiFi QR code with your network name (SSID) and password. Print it and stick it near your router. Guests scan it and connect instantly — no typing the password. Works on all Android phones and iPhones (iOS 11+) with the default camera app.
QR Code for Business Cards and Marketing
Print a QR code on your business card linking to your LinkedIn profile, portfolio or contact page. Add a QR code to product packaging linking to instructions or warranty registration. Use QR codes in print advertisements to track campaign traffic by creating a UTM-tagged URL first. Add QR codes to restaurant menus linking to the online menu.
Frequently Asked Questions
How much data can a QR code hold?
A standard QR code can hold up to 4,296 alphanumeric characters or 7,089 numeric characters. For URLs, keep them short — shorter URLs make simpler, faster-scanning QR codes.
Does the QR code expire?
Static QR codes (like the ones generated here) never expire. Dynamic QR codes (paid services) can be updated after creation.
Can I customise the colour of a QR code?
Yes. The tool lets you change the foreground and background colour. Always ensure high contrast — dark module on light background — so scanners can read it reliably.
Can I scan QR codes with my phone camera?
Yes. On Android (8+) and iPhone (iOS 11+), the default camera app scans QR codes automatically. No separate QR scanner app needed.
