QR codes for URLs, Wi-Fi, vCards, email and SMS — updated live as you type.

A QR code (Quick Response Code) is a two-dimensional barcode developed by Denso Wave in 1994. It can store text, URLs, contact info, Wi-Fi credentials and more, and is read by virtually every smartphone camera without a dedicated app.
This QR code generator supports six content types: plain text, URL, Wi-Fi access (SSID + password), vCard contact, email (mailto:) and SMS. Size, colors and error correction are freely configurable.
QR codes have four error correction levels: L (~7%), M (~15%), Q (~25%) and H (~30%). Higher levels keep the code scannable even when damaged or partially covered by a logo, at the cost of denser modules. M is fine for paper print; use Q or H if you overlay a logo or place the code outdoors.
