Open Qranite's free WiFi QR code generator, enter your network name (SSID) and password, choose your security type (usually WPA), and download the code as PNG or SVG. No signup, no watermark, and the code never expires. Guests scan it with their phone camera and join your network in one tap.
The code itself is just a short text string: your network name, your password, and the security type. Phones read that string and offer to connect. No app, no server, no account is involved. That is also why the code keeps working for as long as your password does.
How do I make a WiFi QR code, step by step?
The whole process takes about a minute. Here is the exact sequence.
- Open the generator. Go to the WiFi QR code generator. No account, no email, no trial clock.
- Enter your network name (SSID). Type it exactly as it appears in your phone's WiFi list. Capitalization counts.
- Enter the password. Also case-sensitive. Copy it from the router label or your router settings if you are unsure.
- Pick the security type. Choose WPA unless your router predates 2006. The table below covers the options.
- Style and download. Logo, colors, and dot styles are free. Download SVG for print, or PNG up to 4096px for everything else.
Which security type should I choose?
Pick WPA. That one setting covers WPA, WPA2, and WPA3, which is nearly every router sold since 2006. The setting tells the scanning phone what kind of connection to expect, so a mismatch means a failed join even if the password is right.
| Setting | Pick it when | Notes |
|---|---|---|
| WPA | Your router was made after 2006 | Covers WPA, WPA2, and WPA3. The right choice for almost everyone. |
| WEP | Hardware from the early 2000s | Obsolete and insecure. Only pick this if your router truly uses it. |
| None (open) | Networks with no password | The code encodes only the network name. |
Why isn't my WiFi QR code connecting?
Four causes account for nearly every failure. First: capitalization. SSIDs and passwords are both case-sensitive, so CoffeeShop and coffeeshop are different networks to a phone. Second: lookalike characters. A capital O typed as a zero, or a lowercase l typed as a one, produces a code that scans fine and connects never.
Third: the wrong security type. A WPA network encoded as WEP will fail silently on most phones. Fourth: hidden networks. If your router does not broadcast its SSID, turn on the hidden network option in the generator so phones know to probe for the name. Some older Android phones still struggle with hidden SSIDs, so consider unhiding the network if guests report problems.
If a code that used to work suddenly stopped, the cause is almost always a changed password — or, with other generators, an expired trial. We wrote up the full list in why did my QR code stop working.
How do I test it before printing?
Tell your phone to forget your network, then scan your own code. If it reconnects, the code is correct. Testing while already connected proves nothing — the phone just stays on the network it already has.
Test at realistic distance. A useful rule: a code scans comfortably from about ten times its own width. A 2-inch code works from roughly 20 inches, which suits a counter or a fridge. Going on a wall across the room? Print bigger. And if you can, test one iPhone and one Android before committing to lamination.
Where should I put a WiFi QR code?
Put it where people ask for the password. At home that is the fridge, the entryway, or a small frame in the guest room. For short-term rentals, a framed card on the kitchen counter answers the question before it gets texted to you at 11pm. Cafés and restaurants do well with table tents or a corner of the menu. Laminate anything that lives outdoors.
Print at 2 inches (5 cm) per side or larger. One inch is the practical minimum, and only at arm's length. One place to avoid: street-facing windows. Anyone who can scan the code can join the network, so keep it where only invited people see it.
Is it safe to put my WiFi password in a QR code?
Two separate questions hide in there. The first is whether the generator sees your password. With Qranite, no. The code is generated 100% in your browser, so your SSID and password never reach our servers — or anyone's. Most online generators submit your form to a backend first. Ours cannot, by design.
The second is physical. The printed code contains the password, so treat the paper like the password itself. Fine on the fridge, unwise taped to a shop window. If you host strangers regularly, put guests on a separate guest network and make the code for that. Your router almost certainly supports one.
Does a WiFi QR code expire?
No. A WiFi code is static: the credentials live in the image itself, so there is no link to expire and no server to shut off. It works until you change your password, at which point you print a new one for free. This is true of static codes from any generator, ours included.
One honest note: WiFi codes cannot be made dynamic in any useful sense. Dynamic codes redirect URLs; WiFi codes hand credentials straight to the phone. Any service selling you an editable WiFi code subscription is selling you a landing page with extra steps.
