What is a QR code?
A QR code (Quick Response) is a two-dimensional barcode that can store many types of data: URLs, text, contact info, GPS coordinates, Wi-Fi credentials, and more. It was invented in 1994 by Japanese company Denso Wave for tracking auto parts, and quickly became popular worldwide thanks to its large storage capacity and fast scan speed.
Unlike traditional 1D barcodes that hold only a few dozen characters, a QR code can contain up to 4,296 alphanumeric characters or 7,089 numeric characters. That capacity makes it ideal for encoding web links, payment info, or even entire paragraphs of text.
QR codes have a built-in error correction system based on the Reed-Solomon algorithm. It lets the code be scanned correctly even if part of it is damaged or covered. The correction level can be set from L (7% recovery) to H (30% recovery) — the higher the level, the more resilient the code, but also the denser.
Our generator creates QR codes directly in your browser, without sending any data to a server. Your information stays 100% private. Customize colors, size, and error correction level, then download as a PNG image or a scalable SVG for maximum quality at any size.
