About QR Code Generator
This free QR code generator creates high-quality QR codes instantly for any content. QR (Quick Response) codes are two-dimensional barcodes that can be scanned by any smartphone camera to instantly access URLs, text, contact information, and more. They are used extensively in marketing, packaging, event tickets, restaurant menus, and business cards.
The tool lets you customize error correction levels to balance between data density and damage resistance. Low error correction creates smaller, simpler QR codes ideal for digital screens. High error correction allows up to 30% of the code to be damaged while remaining scannable, which is essential for printed materials exposed to wear and tear.
Generated QR codes are static, meaning the data is encoded directly in the image and never expires. You can download the QR code as a PNG file at your chosen resolution and use it freely in any commercial or personal project. All generation happens in your browser — no data is sent to any server, and no account is required.
Frequently Asked Questions
What is a QR code?
A QR (Quick Response) code is a two-dimensional barcode that stores data such as URLs, text, contact information, or Wi-Fi credentials. It can be scanned by smartphone cameras and QR reader apps to instantly access the encoded information without manual typing.
What can I encode in a QR code?
You can encode URLs (website links), plain text, email addresses (mailto: format), phone numbers (tel: format), SMS messages, Wi-Fi network credentials, vCard contact information, and geographic coordinates. The most common use is encoding website URLs.
What does error correction level mean?
Error correction allows a QR code to be scanned even if parts of it are damaged or obscured. Low (7%) is sufficient for clean digital use. Medium (15%) is the default and works well for most purposes. Quartile (25%) and High (30%) allow more damage tolerance and are recommended for printed QR codes that may get scratched or partially covered.
What size should my QR code be for printing?
For printed materials, a minimum size of 2x2 cm (about 0.8x0.8 inches) is recommended for close-range scanning. For posters or signs meant to be scanned from a distance, increase the size proportionally. A general rule is 10:1 ratio — at 1 meter scanning distance, the QR code should be at least 10 cm wide.
Do QR codes expire?
Static QR codes (like those generated by this tool) never expire. The data is encoded directly in the QR pattern itself. However, if the QR code links to a URL, the link destination could change or go offline. The QR code image itself will always be scannable.
