Question 1

What is a QR code?

QR (Quick Response) code is a two-dimensional barcode that can be scanned by smartphones to access information instantly. It can store URLs, text, contact information, and more.

Is this service really free?

Accepted Answer

Yes, QRgen.kr is 100% free to use for both personal and commercial purposes. There are no limits on the number of QR codes you can generate.

Question 3

Do the QR codes expire?

Accepted Answer

No. The QR codes generated here are 'static', meaning the information is directly encoded into the image. They will work forever as long as the content (like the URL) remains valid.

Question 4

Accepted Answer

Yes, you can use the generated QR codes for any commercial purpose, such as marketing materials, business cards, or product packaging.

Is my data safe?

Absolutely. We generate QR codes locally in your browser. The data you enter is not sent to our servers, ensuring your privacy is protected.

Question 6

How does the Wi-Fi QR code work?

Accepted Answer

When you scan a Wi-Fi QR code, your smartphone will ask if you want to join the network. It automatically inputs the network name and password for you.

Question 7

Why is my QR code with a logo not scanning?

Accepted Answer

If the logo is too large or covers important parts of the QR code, it might become unreadable. Try reducing the logo size or using a simpler logo. Always test your QR code before printing.

Question 8

Do you provide vector formats like SVG?

Accepted Answer

Currently, we provide high-resolution PNG downloads. We are working on adding SVG support in the future.

Question 9

Can I edit the QR code after generating it?

Accepted Answer

Since these are static QR codes, you cannot edit the content once it's generated. You will need to create a new QR code if the information changes.
