Do these QR codes expire?

No. The data is encoded directly in the image, so there is no redirect service that could ever be shut down. The code works permanently.

What error correction level should I choose?

Medium suits most screen use. Choose a higher level for printed codes that may be scuffed, or where a logo overlaps part of the code.

Can a QR code contain a Wi-Fi password?

Yes. Both iOS and Android recognise the Wi-Fi format and offer to join the network on scan, which is far easier than dictating a long key.

QR Code Generator

What the QR code generator is for

A QR code moves information from a screen or a printed page into a phone without anyone typing it. That removes transcription errors entirely, which matters most for long strings like Wi-Fi keys and URLs.

Because it is generated here in the browser, the content never reaches a third-party service — unlike most online QR generators, which see everything you encode.

Common uses

Sharing a Wi-Fi password with guests without reading it aloud
Putting a link on a poster, business card, or packaging
Encoding contact details for quick scanning
Sharing a long URL that would be painful to type

What the output means in the real world

The image is the encoded payload, not a shortened mystery link unless you put one in. Download the WebP or PNG and keep the source text next to it so you can regenerate after a URL change. For Wi-Fi WIFI:T:WPA;S:...;P:...;; strings, treat the image like the password: do not post it on a public page.

How this fits into real work

Restaurant menus and parking meters made QR phishing ordinary. Confirm the URL domain in the phone preview before you open it. Encoding your own HTTPS URL here is fine; encoding a bit.ly hop is how you lose the audit trail.

Wi-Fi QR codes spare guests from typing a 30-character PSK. Print them for the guest SSID only. A code on the lobby TV that joins the corporate LAN is a standing invitation.

Authenticator enrolment QRs contain the TOTP secret. Display them once, then destroy the image. A photo of the enrolment screen is a second copy of the factor.

How to use this tool

Choose the content type and enter the text, URL, or Wi-Fi details.
Pick a size — larger codes scan more reliably from a distance or in poor light.
Set error correction. Higher levels survive damage and partial obstruction at the cost of density.
Download the image and always test it with a real phone before printing.

Tips

Keep good contrast and a clear white margin around the code; both are essential for reliable scanning.
Shorter content produces a simpler, more scannable pattern — shorten long URLs first.
For anything printed at volume, test scanning from the actual distance people will use.

Privacy & how it works

Everything happens inside your browser. The values you type are held in page memory only, are never sent to a server, and disappear when you close the tab. You can confirm this by opening your browser's network tab and watching it stay silent while the tool runs — or by disconnecting from the internet and using the tool offline. The code is rendered in your browser, so the content is never uploaded — unlike most online QR services.
