Frequently Asked Questions
Common questions about this tool and how it works.
A QR (Quick Response) code is a two-dimensional barcode capable of storing various types of data, such as URLs, text, or contact info, which can be instantly read by smartphone cameras.
QR codes have built-in redundancy. A 'High' error correction level allows the code to be scanned even if up to 30% of it is damaged or obscured (e.g., by a logo in the middle).
No. These are static QR codes, meaning the data is encoded directly into the image pattern. They do not rely on any external server or redirect service, so they will work forever.
Yes. Our generator creates high-resolution images suitable for printing on flyers, business cards, and packaging. Always test scan the printed proof before mass production.
