WIFI:T:WPA;S:Cafe Guest;P:flat white 42;;Wi-Fi QR Code Generator
Guests point a camera at the card and they are on the network. No password typed, no app installed.
This generator builds a Wi-Fi QR code in your browser from your network name, security type and password. Phones read it and offer to join. The code is plain text, not encryption, so print it where you would be happy writing the password — and nothing you type is sent to a server.

PNG for signs and table tents
Wi-Fi codes are usually printed in physical spaces, so a high-resolution PNG is the safest default.
Leave empty for qrcode-YYYY-MM-DD
PNG is best for social media and print. SVG is scalable and perfect for web use.

Background image (Optional)
For best scan reliability, error correction is bumped to High when an image is set. Use a light image with a dark foreground (or vice-versa) for strong contrast.
Logo (Optional)
Built-in icons
Tinted with your foreground color. Pair with high error correction (Q or H).
Use higher error correction (Q or H) when adding a logo to ensure scannability.
Saved Configurations
Save reusable brand or campaign setups, then export them as JSON to share across devices.

§ 01What it encodes
What a Wi-Fi QR code actually contains
| Field | Meaning | Notes |
|---|---|---|
| T | Security type | WPA covers WPA2-Personal and WPA3-Personal alike. Omit entirely for an open network. |
| S | Network name (SSID) | Exact and case-sensitive — "Cafe Guest" is a different network from "cafe guest". |
| H | Hidden flag | Add H:true only when the SSID is not broadcast. There is no H:false; absence means visible. |
| P | Password | Exact text. Semicolons must be escaped, which the generator does for you. |
That is the whole payload. No URL, no redirect, no server — which is why it works with no signal and never expires.
§ 02How to make one
- Step 01
Enter the network name
Copy the SSID exactly as your router broadcasts it, including capitals and spaces.
- Step 02
Pick the security type
WPA for almost every modern network. Use nopass only for a genuinely open one.
- Step 03
Type the password
Punctuation is escaped automatically — semicolons are the ones that silently truncate otherwise.
- Step 04
Style and export
Add a logo or colours if you want, then export SVG or PDF for print, PNG for a screen.
§ 03In practice
Where people use it
- Café and restaurant table cards
- Office and co-working guest networks
- Holiday rentals and Airbnb welcome packs
- Conference and event venue Wi-Fi
- A sticker on the back of the router at home
What breaks it
- Typing the SSID from memory
- Network names are case-sensitive and often contain a trailing space or a hyphen you did not notice. Copy it from the router admin page, not from your phone’s Wi-Fi list.
- Punctuation in the password
- A semicolon ends a field in the WIFI: format. Unescaped, the phone reads a truncated password, tries to join and reports a generic failure that tells the user nothing.
- Printing it too small
- A long password makes a denser grid with smaller modules. A Wi-Fi code usually needs 2.5 cm or more, not the 2 cm a short URL gets away with.
§ 04Questions
- Does the generator escape semicolons in my password?
- Yes. Semicolons, colons, commas, backslashes and quotation marks are escaped automatically when the WIFI: string is built, so a password containing punctuation still works.
- Is my Wi-Fi password sent anywhere when I generate the code?
- No. The string is assembled in your browser and the image is rendered on your device. Nothing is uploaded. If you use the share link, though, the configuration travels inside that URL — treat it like the password itself.
- Can I add a logo to a Wi-Fi code and keep it scannable?
- Yes, with care. Wi-Fi payloads are longer than a short URL, so the grid is already dense. Keep the logo under about a fifth of the area, use high error correction, and scan the result before printing.
- What size should I export a Wi-Fi table card at?
- Export SVG or PDF so size is decided at layout time rather than baked in. For a table tent read at arm’s length, print the code at least 2.5 cm across, and larger if your password is long.
