Generate a QR code for a link, WiFi network, phone number, email, WhatsApp chat, contact card, or plain text — download as PNG or SVG.
No — the QR code encodes your data directly (except WhatsApp links, which point to wa.me). It will keep working forever, with no tracking or expiration.
PNG is a fixed-resolution image, great for most uses. SVG is a vector format that stays sharp at any size — ideal for print.
The password is encoded directly in the QR code image, so anyone who scans it can see or use it — treat the image itself as sensitive.
