WiFi QR code generator
Let guests join your Wi-Fi by scanning, with no password to type. Works even when your password has commas or semicolons in it.
- Free to use
- No account needed
- Tested before you download
- Ready to print
Step 1
What should this code do?
Joins a WiFi network
Exactly as it appears, including capitals.
Punctuation is handled correctly: a semicolon or comma will not break the code.
Step 2 · Make it yours (optional. A plain code works great.)
Colour
Every one of these is dark enough to survive print. Pick one, or set your own below.
Codes with a label are scanned noticeably more often than bare ones.
A logo covers modules. We raise error correction to compensate and then decode the finished code to confirm it still reads.
Higher settings keep the code readable even if it gets scuffed or partly covered, but pack the dots tighter. Standard is right for almost everyone.
Step 3
We’ll tell you exactly how big to print it so it scans easily from that distance.
Common questions
- Does this work on both iPhone and Android?
- Yes. Both read the standard WiFi format from the camera app without an extra application. On iOS the network joins after a confirmation prompt; on Android the behaviour depends on the version but is equivalent.
- My password has a semicolon in it. Will that break the code?
- Not here. The WiFi format treats semicolons, commas, colons and backslashes as structural characters, and a password containing one silently truncates unless it is escaped. We escape them correctly, which is a common source of codes that scan but fail to connect.
- Is my password sent anywhere?
- No. The code is generated entirely in your browser. Your password is encoded into the image on your own device and never reaches our servers.
Before you print
Size is the most common failure, but it is not the only one.
- Test the actual print, not the screen
- Scan it from the physical proof, at the distance and in the lighting people will really use, with an older phone if you have one. A code that scans on a monitor can fail on paper.
- Keep the quiet zone empty
- The blank margin around the code is part of the code. Scanners use it to find the edges. Placing text or a border inside it is the most common design mistake.
- Avoid glossy lamination where you can
- Gloss reflects overhead light straight back into the camera and washes out the pattern. Matt finishes scan far more reliably indoors.
- Do not print on a curve if you can avoid it
- Bottles, cups and cylinders distort the pattern. If you must, keep the code small relative to the curve and use a higher error correction level.
- Tell people what they get
- A code with no label is scanned far less often than one that says what happens next. 'Scan to see the menu' outperforms a bare code consistently.
