How to create a Wi‑Fi QR code

  1. Enter your network name (SSID) exactly as it is broadcast.
  2. Select WPA/WPA2-Personal or Open (no password). WPA3-only and enterprise networks are not guaranteed to work.
  3. Add the Wi‑Fi password (case-sensitive) unless the network is open.
  4. Toggle “Hidden network” if your SSID is not broadcast.
  5. Adjust size, margin, and colors; generate and download PNG or SVG.
  6. Print, display, or open the printable sign generator for guest-ready signage.

Why Use This Wi‑Fi QR Code Generator?

A Wi‑Fi QR code contains the network name, security type and password in readable form. This generator builds it in your browser without uploading or saving those fields. Anyone with the image can read the credentials, so use a separate guest network and share the code only where intended.

  • Encode WPA/WPA2-Personal or open guest Wi‑Fi; test compatibility with your router and guest devices.
  • Support for hidden SSIDs where the network is not broadcast.
  • Custom size, margin, and colors for signage, stickers, or table tents.
  • Download print-ready PNG or SVG files; no watermarks, no sign-up.

Where Wi‑Fi QR Codes Shine

Wi‑Fi QR codes reduce friction anywhere guests connect:

  1. Short-term rentals and hotels with rotating guest networks.
  2. Events, conferences, and co-working spaces at check-in.
  3. Cafes, clinics, and lobbies to cut “what’s the Wi‑Fi?” questions.
  4. Offices using separate guest VLANs for visitors.

Frequently Asked Questions

Is this Wi‑Fi QR code generator really free?

Yes. It runs entirely in your browser. Create unlimited Wi‑Fi QR codes without accounts or watermarks.

Are my Wi‑Fi credentials stored?

The generator does not upload or save the fields you enter. The site still makes ordinary requests to load the page and its existing analytics. Downloaded QR images contain readable credentials and may be shared or synced by your device. Do not put passwords in URLs or analytics fields.

Which security modes are supported?

The standard WPA payload targets WPA/WPA2-Personal; open networks use no password. WPA3-only, enterprise sign-in and captive portals are not guaranteed to work. Keep your router’s appropriate security settings and use manual joining when needed; do not downgrade security just for a QR code.

Do you support hidden SSIDs?

Yes. Check the hidden network option so scanners include the hidden flag.

Can I change colors or add a label?

Use dark modules on a light background and leave at least four clear modules on every side. The tool blocks low-contrast or inverted colors, but a color check is not proof of scanning reliability. Put labels outside the quiet zone; do not cover the code with a logo.

Why does a code scan but fail to join?

First try joining manually using exactly the same name and password, including spaces and capitalization. Then check the security type and hidden-network setting. Names or keys made only of 0–9 and A–F can be interpreted as hexadecimal by some scanners; this tool preserves them without adding wrapper quotes, so test the intended devices or join manually. Changing a router password does not update an old downloaded code: generate and replace it.

Printable WiFi QR Code Sign

If you need a guest-facing sign instead of a plain QR file, use the printable sign generator. It adds a clear scan instruction, SSID label, fallback password text, and venue-friendly layouts for cafes, hotels, offices, rentals, and events.

More ways to get reliable scans

  • Use a guest SSID: Isolate visitor traffic from your main network; rotate the guest password on a schedule.
  • Prefer WPA2/WPA3: Only use “Open” for truly public networks. Hidden SSIDs may still need manual confirmation on some devices.
  • Size for the medium: This generator produces PNGs up to 600 px, rounded down to whole module pixels. Use SVG for larger layouts, keep the quiet zone, and test the final physical size and viewing distance.
  • Maximize contrast: Dark code on a light background; avoid low-contrast brand colors or busy backdrops.
  • Cross-device testing: Test with current iOS/Android cameras before printing a batch; check under real lighting to avoid glare.

Security and privacy

Guest-first approach

Use a guest SSID whenever possible so you can rotate passwords without exposing your main network. Avoid posting your primary SSID or private credentials publicly.

Strong credentials

  • Use WPA2 or WPA3 with 12+ character passphrases; avoid reusing old keys.
  • Rotate guest passwords weekly for public venues or per booking for rentals.
  • Add a "Last updated" note on printed cards and recycle old prints after rotation.

Data handling

All QR generation runs locally in your browser; SSIDs and passwords are not sent to a server. Disable JavaScript or use content blockers if you prefer to avoid analytics or ads entirely.
