Frequently Asked Questions about QR Codes
What is a QR Code?
QR Code (Quick Response Code) is a two-dimensional barcode that can store information such as URLs, texts, phone numbers, emails and much more. Created in Japan in 1994, it is widely used to facilitate quick access to digital information.
How to scan a QR Code?
Most modern smartphones have native QR Code readers in the camera. Open the camera, point at the QR Code and tap the notification that appears. There are also specific apps like QR Code Reader, Google Lens and Zxing.
Can I customize colors?
Yes! Our tool allows you to customize both the QR Code color and the background color. We recommend maintaining high contrast (eg: black on white) to ensure good readability by readers.
Is it really free?
Totally free! There are no usage limits, mandatory registration or hidden fees. You can generate as many QR Codes as you want and download them in high-quality PNG at no cost.
What's the best size for printing?
For printing, we recommend sizes between 500-800px. For digital use (websites, emails), 200-400px is sufficient. The important thing is to maintain the proportion and ensure that the QR Code is scannable at the final size of use.
Is the data secure?
Yes! All processing is done locally in your browser. Your data is not sent to our servers, ensuring complete privacy and security of the information entered.
