QR Code Generator
Turn any link or text into a QR code you can download and share. Generated instantly in your browser.
How QR codes actually work
A QR (Quick Response) code is a two-dimensional barcode that encodes data — typically a URL or short text — into a grid of black and white squares that a camera can read and decode almost instantly. Unlike a traditional one-dimensional barcode, which can only store a limited string of numbers, a QR code's two-dimensional structure allows it to hold significantly more data, including full web addresses, contact information, or short messages.
This tool encodes whatever text or link you provide directly into a QR code image using your browser, entirely on your device. Any smartphone camera app (or a dedicated QR scanner) can then read that code and take the user directly to the encoded link or display the encoded text.
Common uses for QR codes
QR codes are widely used on printed materials — business cards, flyers, restaurant menus, product packaging, and posters — as a bridge between physical and digital content, letting someone move from a printed page straight to a website without typing a URL manually. They're also commonly used for sharing Wi-Fi credentials, contact details, event registration links, and payment information.
Why QR code density matters
The more data you encode into a QR code, the denser and more complex its pattern becomes, which can make it harder for some cameras to scan reliably, especially at a small printed size. Keeping the encoded content concise — a short URL rather than a long one, for example — generally produces a QR code that's easier and faster to scan.
What can I put in a QR code?
Any URL, plain text, or short message. Keep it concise — very long text produces a denser, harder-to-scan code, especially if it will be printed at a small size.
Do QR codes expire?
No, a QR code generated this way encodes the content directly and works for as long as any linked destination remains valid — the code itself doesn't have an expiration date.
Why won't my QR code scan?
Common causes include the code being printed too small, poor lighting or a low-quality printout, or the encoded content being too long and dense. Try generating it at a larger size or shortening the URL first.
Is it safe to scan any QR code?
Exercise the same caution you would with any link — a QR code can point to a malicious website just as easily as a legitimate one, so be cautious about scanning codes from unfamiliar or untrusted sources.
