A QR (Quick Response) code is a 2D barcode that stores data in a matrix of black and white squares. When scanned with a smartphone camera or QR reader, it instantly opens a URL, shows text, dials a number, connects to WiFi, or saves a contact — no manual typing needed.

Yes — 100% free, no signup, no watermarks, no limits. You can generate unlimited QR codes and download them in PNG or SVG. All processing happens in your browser; your data never leaves your device.

Error correction lets a QR code be scanned even if it's partially damaged. Levels: L (7%), M (15%), Q (25%), H (30%). Higher levels are better for printed materials or when you want to overlay a logo. For digital use, M is fine.

Download PNG for digital use — websites, emails, WhatsApp, social media. Download SVG for print — business cards, banners, brochures, signage. SVG is infinitely scalable without quality loss, making it ideal for any print size.

QR codes made here are static — they never expire on their own. They work as long as the destination (URL, WiFi, contact) exists. If your webpage is deleted, the QR code will still scan but show an error. Dynamic QR codes (editable after printing) require paid third-party services.
