WiFi QR Code Generator

WiFi QR Code Generator

Generate branded WiFi QR codes with your logo and colors. Scan to auto-connect — no typing. WPA3/WPA2/WEP, open and hidden networks, scannability check.

How does a WiFi QR code work?

Your phone camera reads the QR code's WIFI: payload and prompts to join the network. iOS 11+, Android 10+, and most camera apps support this natively without a separate scanner.

Is my password sent anywhere?

No. The QR code is built entirely in your browser using a small JavaScript library. Nothing leaves your device — no server upload, no logging, no tracking.

Which security types are supported?

WPA / WPA2 / WPA3 (share the same type token), WEP, and open networks (no password). WPA3-only routers without WPA2 fallback may still need manual setup on older devices.

Why does my generated QR code not connect?

Common causes: SSID typo (case-sensitive), wrong security type, special characters in SSID/password that need escaping, or 5GHz-only network that the scanning phone doesn't support.

Can I use this for a hidden network?

Yes — check the 'Hidden network' box. Note that some Android versions still won't auto-connect to hidden networks from QR; the user may need to manually add it.

What's the largest password I can encode?

WiFi passwords are limited to 63 characters by the WPA standard. The QR code itself can hold more, but anything beyond that won't work on the network.

How should I print the QR for guests?

Pick the 512×512 or larger size, print on white paper, and keep at least 1 cm of white margin around the code. Avoid glossy paper that reflects flash during scanning.

Why won't my QR code with a logo scan?

A centred logo covers part of the code, so the scanner must reconstruct the missing modules from error-correction data. Keep the logo at 20–25% of the QR width or less and use error-correction level Q or H. This tool automatically forces level H whenever a logo is added so the code stays readable.

What error-correction level should I use?

L (7%) and M (15%) are fine for plain codes on clean surfaces. Use Q (25%) for printed codes that may get scuffed, and H (30%) whenever you overlay a logo or print at small sizes. Higher levels add more modules but greatly improve real-world scan reliability.

Can I match the QR to my brand colors and still keep it scannable?

Yes, but keep dark modules on a light background — most scanners reject light-on-dark (inverted) codes. Aim for a contrast ratio of at least 4.5:1 (3:1 is the bare minimum). The built-in scannability check measures your foreground/background contrast and warns you before you print.

What size should I print the QR code for scanning at a distance?

Follow the 10:1 rule: scan distance should be about ten times the code's printed width. A 3 cm code scans reliably at ~30 cm (a table tent), while a poster read from 3 m needs roughly 30 cm. Print at 300 DPI, keep the quiet-zone margin, and prefer a vector source when scaling large.
