Frequently asked questions
What is QR4URL?
QR4URL is a free QR code generator with scan tracking. You can create QR codes for links, text, email, phone numbers, SMS, WiFi, UPI payments and contact cards.
What is a QR code?
A QR (Quick Response) code is a square barcode that stores information such as a link or text. A phone camera reads it in a moment.
How does a QR code work?
A QR code is a pattern of small squares that encodes data. The camera finds the three large corner squares to see the direction, then reads the pattern. Built-in error correction lets a code scan even if a small part is damaged.
How do I scan a QR code with my phone?
Open the camera app, point it at the code and tap the link or message that appears. Many phones also have a QR scanner in the camera settings or in Google Lens.
Are QR codes safe to scan?
A QR code is only data, so the risk is where it sends you. Check the link before you open it, be careful with stickers placed over other codes, and never enter passwords or card details on a page you do not trust.
What is the difference between a QR code and a barcode?
A normal barcode is one-dimensional and holds a short number. A QR code is two-dimensional, holds much more data such as links and text, and can be scanned from any angle.
What size should a printed QR code be?
Print it at least 2 cm (about 0.8 in) wide for close scanning. For scanning from far away, make it bigger. A common rule is about 1 unit of size for every 10 units of distance.
Can I scan a QR code from a screen or screenshot?
Yes. Scan it with a second phone, or open the screenshot in your gallery and use Google Lens or your phone's scanner.
How does scan tracking work on QR4URL?
With tracking on, the QR code points to a short QR4URL link. When someone scans it, we count the scan and then open your content. You see the totals with your Tracking ID. Read our Privacy Policy for the details we store.
Is QR4URL really free?
Yes. You can create, style and download QR codes for free, with no account.
