Generate a QR code from any URL or text. Everything runs in your browser — nothing is uploaded.
A QR code (Quick Response code) is a two-dimensional barcode that stores information in a grid of black and white squares. Originally developed in 1994 by Denso Wave for tracking car parts in manufacturing, QR codes have since become one of the most widely used methods for sharing information quickly between the physical and digital worlds.
QR codes encode data using a pattern of dark and light modules arranged in a square grid. The three large squares in the corners help scanners detect the code's orientation, so it can be read from any angle. The remaining modules store the actual data along with error correction information. This error correction means a QR code can still be read even if up to 30% of it is damaged or obscured, making them remarkably resilient.
A standard QR code can hold up to around 4,296 alphanumeric characters or 7,089 numeric digits. The more data you encode, the denser and larger the QR code becomes. For most practical uses like URLs, Wi-Fi credentials, or contact details, the resulting code stays compact and easy to scan.
QR codes appear everywhere in daily life. Restaurants use them for digital menus. Retailers print them on packaging to link to product information or promotional offers. Event organisers embed them in tickets for quick check-in. Businesses put them on business cards to share contact details instantly. They are also widely used for mobile payments, Wi-Fi network sharing, app download links, and two-factor authentication.
This generator creates QR codes entirely in your browser. Your data never leaves your device — there is no server involved. Simply type or paste your text, generate the code, and download it as a PNG image ready for print or digital use.
