What this tool does

A focused job, with a visible boundary.

Build an inspectable QR code in your browser without submitting its contents to a QR service.

01

URL, Wi-Fi, contact, email, phone, SMS, and text modes

02

Exact payload preview

03

PNG and SVG downloads

Know the limits

Local does not mean unlimited.

Browser processing protects the file from an upload workflow, but the browser, device, output format, and selected settings still matter.

  • Anyone who can scan the finished QR code can read its contents.
  • A QR code does not prove that a URL or contact is trustworthy.
  • Complex payloads create denser codes that can be harder for cameras to scan.

Clear answers

QR generator questions.

Does NullKit receive the QR content?

No. Payload construction and QR rendering happen in the current browser tab.

Can I make a Wi-Fi QR code?

Yes. Enter the network name, security type, and password. Anyone with the resulting code may be able to join that network.

Do generated QR codes expire?

No. These are static codes containing the information directly. They continue to work while the encoded destination or credentials remain valid.
