Wi-Fi QR code

Wi-Fi QR code

Type the network name and password. The code is built on this page — the password is never sent to our servers. Download four ready-to-cut guest cards as an A4 or US Letter PDF, or a QR image for your own layout.

Content

Your QR code updates as you type. For WPA or WEP, enter the password. For an open network, choose No password. Network names support up to 32 UTF-8 bytes. The password is never uploaded.

Static code — the data is baked in. Nothing is uploaded, and there is no link to edit later. It does not expire; to change it after printing, you print a new one.

What the code actually holds

A Wi-Fi QR code is not a link. Phones read a short WIFI: string with the network name, the security type and the password, then offer to join. There is nothing to edit later, which is why this page does not create a dynamic short URL. If you change the password, you print a new code.

Where it works

Phone support varies by camera, scanner and network settings. Test the downloaded code on the phones your guests use, and confirm that they join the intended network. Select Hidden network only if your access point does not broadcast its name. Keep manual joining instructions available.

How to make a Wi-Fi QR code

  1. Enter the networkType the exact SSID. It is case-sensitive. Tick hidden network if the name does not appear in the phone’s Wi-Fi list.
  2. Add the passwordPaste it once and glance at it — the field is plain text so you can check it before you print. Nothing is uploaded.
  3. Download and printChoose A4 or US Letter and Download guest cards for four 90 × 120 mm cards with manual joining details. Print at 100% actual size rather than fit-to-page, measure a 90 mm edge and cut along the guides. For your own layout, download PNG or SVG. Put the code on a light background and preserve the white margin around it. Print one card at the intended size before making a batch; screen recognition alone does not prove the print works.
  4. Confirm the connectionScan the printed card, check the network name and confirm the phone joins successfully. If the name or password changes, generate a new code and replace every old card. Use a guest network whose owner has approved sharing it.

Check your QR before printing

Keep the full clear margin around your downloaded QR. Print one proof at the final size, measure it, and scan it with the phones your visitors use before ordering a batch.

Compare QR print dimensions and make an A4 or US Letter proof for a plain, no-logo static link or text code. For your existing dynamic code, paste its Qex short link, rather than the destination, to keep the same redirect in the proof. For a code with a logo, frame, Wi-Fi details or a contact card, test the actual downloaded artwork; the plain calculator does not reproduce that design.

Diagnose a QR code that will not scan or open if a proof fails.

Questions

Is the Wi-Fi password sent to Qex?

No. This page assembles the WIFI: string and draws the code in your browser. The downloaded image contains the network details, including the password. Anyone with the image can read those details; closing the tab does not remove downloaded or printed copies.

Can I change the password later without reprinting?

Not with a Wi-Fi code — the password is inside the pattern. Reprint when the network changes. For a link you might change (a menu, a review page), use a dynamic code instead.

Will it work on iPhone and Android?

Compatibility depends on the phone, scanner and network configuration. Scan a test print with your target iPhone and Android devices, then confirm a successful connection. A scanner may show the raw WIFI: text instead of offering to join.

Should I put this on a public street poster?

Only for a network you are happy strangers will join. A guest network with a password you can rotate is safer than the shop’s admin Wi-Fi.

Text QR codeA text QR code stores your words inside the code itself: a scanner shows the message with no website and no internet connection. Type up to 800 characters and Qex encodes them in a static QR code you download free, with no account. Shorter text gives a smaller, easier-to-scan code: 100 characters make a 41×41 grid. Some phone cameras do not display plain text. Want words people can read on the printed code too?

A compatible scanner can open a draft in the visitor’s mail app. Scanning does not send a message; check the recipient and subject before printing.QR code for a menuStart with a menu your guests can open on a phone without signing in.
