How to Create a Free QR Code Online — URL, WiFi, vCard and More

QR codes are everywhere: restaurant menus, shop windows, business cards. Creating them doesn't require expensive software — it takes a few seconds with the right tool.

What Can You Encode in a QR Code?

A QR code can contain any text, but there are standardised formats that smartphones recognise automatically:

| Type | What the phone does when scanned | |------|----------------------------------| | URL | Opens the website in the browser | | WiFi | Offers to connect to the network | | vCard | Offers to save the contact | | Email | Opens the email client with recipient pre-filled | | Phone | Asks if you want to call the number | | Text | Displays the raw text |

How to Create a QR Code with QR Lab

The Saloneylab QR Generator is free and runs entirely in your browser — no data is ever sent to any server.

1. Choose the type (URL, WiFi, vCard…)
2. Enter the content
3. Customise size, colours and error correction
4. Add your logo (optional)
5. Download PNG or SVG

How to Add a Logo to the Centre

QR Lab supports placing a logo at the centre of the QR code. For best results:

• Use a PNG with a transparent background (ideal for brand logos)
• Error correction is automatically set to H (30% recovery) — meaning up to 30% of the code can be covered by the logo and the QR remains perfectly scannable
• The logo is scaled to ~22% of the total size — beyond this threshold, scannability may be affected

Which Format to Download: PNG or SVG?

• PNG: ideal for web, email, presentations. Choose 512px or 1024px for quality prints.
• SVG: vector format, scales to any size without quality loss. Perfect for professional printing (posters, banners, brochures).

WiFi QR Code — The Most Practical Use Case

A WiFi QR code is probably the most useful in everyday life. Instead of dictating your password out loud (with the risk of typos), just print the QR code and display it near the router. Guests scan and connect without typing anything.

The generated code format:

WIFI:T:WPA;S:NetworkName;P:password123;;

Works natively on iOS 11+ and Android 9+, no app required.

Free, Private, Client-Side

Unlike many online generators that send your content to their servers (and often sell that data), QR Lab generates everything directly in your browser. Your WiFi password, phone number or email never leaves your device.
