What is the QR Code Generator?
A QR code generator converts any text, URL, phone number, or data into a scannable square code. Smartphones running iOS 11+ or modern Android can scan them natively with the camera — no extra app needed. BlueQRCode generates QR codes entirely in your browser, so nothing you enter is ever sent to a server.
When to use this tool
- ✓Linking a printed flyer, poster, or billboard to a webpage without making people type a URL
- ✓Embedding contact details or WiFi credentials in a business card or sign
- ✓Driving traffic from physical product packaging to a landing page, video, or review form
- ✓Event check-ins, table menus, conference badges, or anywhere you want zero-friction access
- ✓Sharing plain text — instructions, discount codes, or messages — that should be readable offline
How to use the QR Code Generator — step by step
- 1
Choose what to encode
Type any URL, plain text, phone number, or other data into the input field. Shorter content produces a simpler, easier-to-scan code.
- 2
Customize appearance (optional)
Adjust the foreground and background colors to match your brand. Keep contrast high — low-contrast codes fail scanners.
- 3
Preview the code live
The QR code updates in real time as you type. Check that all details are correct before downloading.
- 4
Test before printing
Scan the on-screen preview with your phone to confirm it decodes correctly. Do this on both iOS and Android if possible.
- 5
Download PNG or SVG
Use PNG for digital use or documents. Use SVG for print — it stays sharp at any size, from a business card to a billboard.
- 6
Place and track
Add to your materials. If you need tracking, use a UTM-tagged URL so you can measure scans in Google Analytics.
