The Bridge Between Physical and Digital
You’re setting up a conference booth and need a QR code that links to your landing page. Or you’re printing business cards with a vCard QR code so people can save your contact info with one scan. Or you just moved into a new apartment and want a QR code on the fridge so guests can connect to WiFi without asking for the password.
This tool generates standard QR codes from text, URLs, email addresses (with pre-filled subject and body), phone numbers, WiFi credentials, and vCard contact information. The output renders on an HTML canvas and downloads as a PNG. Every QR reader app and phone camera on the market can scan it.
WiFi QR Codes Are Magic
Select the WiFi mode, enter your network name, password, and encryption type (WPA2 for most networks). The generated QR code lets anyone connect to your WiFi by pointing their phone camera at it. No more spelling out xK9$mP2! one character at a time.
iOS added native QR WiFi support in iOS 11. Android’s had it for years. The QR code contains a standard WIFI:T:WPA;S:NetworkName;P:Password;; string that both platforms understand.
Printing Guidelines
Minimum size: 2x2 cm (about 0.8 inches). Below that, phone cameras struggle to focus and resolve the modules.
Distance rule: 1/10th. If people will scan from 2 meters away (a poster on a wall), the QR code should be at least 20 cm on each side.
Data density matters. A URL like https://example.com produces a sparse, easy-to-scan QR code. A vCard with full contact details produces a much denser one that needs to be printed larger.
Test before mass printing. Generate the code, print one copy, scan it with at least two different phones. Then print 5,000.
Beyond URLs
vCard business cards. Encode your name, title, phone, email, and company into a QR code. Stick it on your business card. People scan it and your full contact info saves directly to their phone.
Event check-in. Generate unique QR codes for each registrant. Scan at the door with the QR Code Reader for instant check-in.
Product packaging. Link to assembly instructions, warranty registration, or ingredient information. Consumers scan instead of hunting for tiny URLs printed in 6pt font.
Restaurant table tents. The COVID-era digital menu trend stuck around because it works. Generate a QR code linking to your menu, laminate it, put it on every table.
The QR code holds up to 4,296 alphanumeric characters, but keep it short. Less data = fewer modules = smaller printable size = easier scanning.
For linear barcodes (shipping labels, inventory), the Barcode Generator handles Code 128. The QR Code Reader scans and decodes QR codes from uploaded images or camera.
All generation runs in your browser. Your WiFi password, contact info, and URLs stay on the page.
