Generate a QR code for Wi-Fi credentials
Create a scannable Wi-Fi QR code that auto-connects iPhones and Androids. Password stays in your browser — never uploaded.
Generate a QR code for Wi-Fi credentials
Wi-Fi QR codes are the modern "print-it-and-stick-it" way to share network credentials with guests in a café, co-working space, hotel, or home. The data is encoded as a WIFI: format string (SSID + password + security type) that every modern phone camera recognises. This preset generates the code entirely in your browser, so the password never transits our servers — an important property for Wi-Fi keys that control network access to printers, security cameras, and other devices.
What is Generate a QR code for Wi-Fi credentials?
Generate QR codes for URLs, plain text, Wi-Fi credentials, contact cards, and any string up to about 2k characters.

Common pitfalls and how to avoid them
- Scanner cannot read the code — Increase the module size (print larger) or bump error-correction to "High" to survive surface damage and reflection.
- Logo obscures the data — Keep the logo to ≤20% of the total area and use error-correction level Q or H so the reader can reconstruct missing modules.
- Wi-Fi QR does not auto-join — Check the format string: WIFI:T:WPA;S:<name>;P:<pass>;;. iOS 16+ and Android both honour this when the camera scans it.
When should I use Generate a QR code for Wi-Fi credentials?
QR Generator creates new codes. To read an existing QR code (from image or camera), use QR Scanner. For barcodes (EAN, UPC, Code128), use Barcode Generator.
Will my iPhone auto-join?
iOS 16+ auto-joins from Wi-Fi QR scans. Older iOS and some Androids prompt you to join — one tap either way.
Is my password sent to your server?
No. The QR is generated entirely in your browser via JavaScript — the password string is encoded locally and never transmitted.
Can I add a logo?
Yes — upload a PNG and we centre it inside the code with error-correction level H (30% recovery) so scanners still read it.
Is my file uploaded anywhere?
No. Everything runs in your browser — the file never leaves your device, and there is no server component for this tool.
