How to Make a WiFi QR Code

1. Open the WiFi QR code generator: /wifi-qr-code-generator 2. Enter your network name (SSID) exactly as it appears in your WiFi settings — capitalization matters. 3. Pick the encryption type: WPA/WPA2/WPA3 for almost any modern network, WEP for legacy gear, None for an open network with no password. 4. Enter the password, exactly as it is. 5. Customize the look if you want — logo, colors, dot style. These don't affect scannability as long as error correction stays high. Download, print, done. That's the whole workflow for a static WiFi QR.

Case-sensitive SSIDs. Most home routers broadcast something like "Home_WiFi_Network" — and the QR has to match that exact casing. If you typed it lowercase but the router broadcasts mixed case, the join will silently fail. Special characters in passwords. Spaces, ampersands, and quotes all work, but they need correct encoding. The generator handles this for you; if you're hand-crafting a WIFI: payload yourself, you'll need to escape those characters manually. Hidden SSIDs. If your network is hidden (not broadcasting), the QR has to explicitly say so. Otherwise the scanner's phone looks for the network in the list of nearby networks, doesn't find it, and gives up. The Build QR generator has a "hidden network" toggle for exactly this. Enterprise WPA. WPA-Enterprise (802.1X with RADIUS, common in corporate WiFi) isn't supported by the standard WIFI: QR format. Only WPA-Personal is. If your network needs a username and password (not just a password), QR codes can't help — use the corporate WiFi provisioning profile mechanism instead.

WiFi QR codes usually get scanned from up close — counter cards, table tents, mirrors in hotel rooms. The general rule of thumb is 1 cm of QR width per 10 cm of scanning distance. • Close-range scans (under 30 cm): 2-3 cm square is plenty. • Wall posters at conversation distance (1-2 m): 8-12 cm square. • Visible from across a room (3-5 m): 25-40 cm square. Always test the printed code with at least one iPhone and one Android before committing to a print run. Android's camera app is a touch slower at detecting QR codes in low light than iOS is, so test in the lighting where the code will actually live.

Static WiFi codes are fine if your network password never changes. But if you rotate it — quarterly, after an event, when a contractor leaves — every printed static code dies the moment you change it. A dynamic WiFi QR redirects through a Build QR link to a small page that shows the current credentials. Update the page; every printed code stays valid. As a bonus, you get scan analytics — useful for offices wondering whether the guest WiFi actually gets used. See the dynamic QR generator for details.
