QR Code FAQ

What is a QR code?

A QR code (Quick Response Code) is a matrix barcode used to encode and store information.

It was invented in 1994 by Japan's Denso Wave and was initially used to track parts in the automotive manufacturing industry. Today QR codes are widely used across many fields, including payments, information storage, and identity verification.

How long is a QR code valid?

A QR code itself has no time limit—it is a static image, and the QR code remains valid as long as its content is accessible. However, if the URL contained in the QR code expires, the QR code will not be able to access the corresponding content.

What content does the QR code generator support?

The online QR code generator supports URLs, text, email addresses, phone numbers, business card information, and more—any text content can be turned into a QR code.

Can the generated QR code be printed?

Yes. The QR codes generated by this tool are high-definition images that can be used directly in printing, promotional materials, or business cards.

How do I ensure the QR code is clear?

You can adjust the QR code size in the settings; the larger the value, the clearer the generated image, which is better for printing.

Are colored QR codes supported?

Yes. You can customize the foreground and background colors to generate a colored QR code.

What format is the downloaded QR code?

The online QR code generator downloads images in JPG format by default, making them easy to share and use.
