Can I create a URL QR code without signing up?

Yes! With Online-QR, you can generate QR codes by simply using our API URL: https://api.online-qr.com/v1/make-qr?data=YOUR_URL. No signup, no account, no SDK needed.

Can I change the URL after the QR code is printed?

Yes, if you create a Dynamic QR code. Dynamic QR codes use a short redirect URL that you can update anytime without changing the printed QR code. Create a free account to use dynamic QR codes.

Is there a limit to how many URL QR codes I can generate?

No! Static QR code generation via the API URL is completely free and unlimited. For dynamic QR codes with tracking, the free tier includes generous limits.

What size should my URL QR code be for print?

For reliable scanning, print URL QR codes at a minimum of 2cm x 2cm (about 0.8 inches). For posters or signs viewed from a distance, scale up proportionally — at least 1cm of QR code size per meter of scanning distance.

What is a URL QR Code?

A URL QR code encodes a web address (URL) into a scannable QR code. When someone scans it with their phone camera, they are taken directly to the linked webpage. URL QR codes are the most common type and are used on business cards, flyers, posters, product packaging, and digital media. They bridge the physical and digital worlds by letting people navigate to any website without typing an address.
