What Is a QR Code and How Does It Work?
A QR (Quick Response) code is a two-dimensional barcode that stores information in a pattern of black and white squares. When scanned by a smartphone camera or QR reader app, it instantly decodes the stored data - whether that's a URL, plain text, WiFi credentials, or contact information.
- QR codes can store up to 7,089 numeric characters or 4,296 alphanumeric characters
- They include built-in error correction, working even when partially damaged
- Modern smartphones can scan QR codes directly through the default camera app
- QR codes never expire - they work as long as the encoded content is accessible
Types of QR Codes You Can Create for Free
URL QR codes are the most common type, directing scanners to a website. WiFi QR codes let guests connect to your network without typing passwords. Text QR codes can contain messages, notes, or any plain text up to several thousand characters.

QR Code Best Practices for Business
When using QR codes for business, size matters. A QR code should be at least 2cm x 2cm (0.8 x 0.8 inches) for reliable scanning. For posters or billboards, increase the size proportionally. Always include a call-to-action near the code, like 'Scan for Menu' or 'Scan to Connect to WiFi'.
Free QR Code Generator vs Paid Options
Free QR code generators like ours create static QR codes that permanently encode your data. Paid services typically offer dynamic QR codes where you can change the destination URL after creation, plus analytics tracking. For most personal and small business use cases, free static QR codes work perfectly.

QR Code Generator →Frequently Asked Questions
Are free QR codes really free forever?
Yes, static QR codes generated by free tools work forever. The data is encoded directly in the QR pattern, so there's no service dependency. Your QR code will work as long as the content it links to exists.
What is the best image format for QR codes?
PNG is the best format for most uses. It provides high quality with a small file size. For print materials requiring very large sizes, SVG format is ideal as it scales without losing quality.
Can I create a QR code for WiFi password sharing?
Yes! WiFi QR codes encode your network name (SSID), password, and encryption type. When scanned, the phone automatically connects to the WiFi network without manual password entry.
How small can a QR code be and still work?
The minimum recommended size is 2cm x 2cm (about 0.8 inches). For scanning from a distance of 1 meter, the code should be at least 10cm x 10cm. The general rule is: scanning distance divided by 10 equals minimum QR code size.
