Question 1

What types of content can I encode in a QR code?

Accepted Answer

You can encode any text, URL, email address, phone number, SMS message, Wi-Fi credentials (SSID and password), or plain text up to approximately 3,000 characters.

Question 2

How long does a QR code last?

Accepted Answer

A static QR code lasts forever — it is an image encoding your data directly. There is no server dependency, no expiry date, and no tracking unless you use a third-party dynamic QR service.

Question 3

Can I add a logo or customise the QR code?

Accepted Answer

You can adjust the size and error correction level. Level H allows up to 30% of the code to be damaged and still scan correctly, making it safe to overlay a small logo in the centre.

Question 4

Can I download the QR code?

Accepted Answer

Yes. Download as a PNG at any resolution. The file has no watermark and is free for personal and commercial use.

Question 5

Is my data sent to a server when generating?

Accepted Answer

No. QR codes are generated entirely in your browser using a local JavaScript library. Your input is never uploaded or stored anywhere.
