QR Code Details

0 / 2,000

L restores about 7% · M about 15% (recommended) · Q about 25% · H about 30% of damaged QR data. Higher correction levels can make the QR pattern denser.

QR codes are generated only in this browser. Wi-Fi passwords and contact details are not sent to Utilook.

What can this QR code include?

Choose a content type and enter the details people should receive after scanning. Use URL for a website, Wi-Fi for a network connection, or vCard for a contact card. Each format is created as one QR code option rather than a separate page.

Choose content that scanners understand

A URL opens a page, Wi-Fi data proposes network settings, and vCard data creates a contact record. The scanner decides how to handle that payload, so test the generated code on both major mobile platforms before printing or distributing it.

Capacity, density, and print reliability

Longer content and higher error correction produce denser patterns with smaller modules. Use the shortest practical text, strong foreground-background contrast, an undisturbed quiet zone, and enough physical size for the expected scanning distance.

Frequently Asked Questions

Is my QR code data uploaded?

No. QR creation runs in your browser. The text, Wi-Fi password, and contact details are not sent to or stored by Utilook.

Which Wi-Fi security types are supported?

Choose WPA/WPA2, WEP, or no password. A person scanning the code still needs permission to join the network.

Can I use Korean or emoji?

Yes. The QR code is encoded as UTF-8 so Korean and other Unicode text can be included.

Why does a very long value fail?

QR codes have a finite capacity. Shorten the content or use a lower error-correction setting for more room.

What is QR code error correction?

Error correction helps a QR code remain scannable when part of it is scratched, covered, or poorly printed. L can recover about 7%, M about 15%, Q about 25%, and H about 30% of damaged data. M is recommended for most uses. Q or H can be useful when part of the QR may be obscured or printing conditions are poor. Higher correction levels can make the QR pattern denser.
