Frequently Asked Questions
What is a QR code?▼
A QR (Quick Response) code is a two-dimensional barcode that can store text, URLs, contact information, and more. It can be scanned by smartphone cameras and QR reader apps to quickly access the encoded information.
What is error correction in QR codes?▼
Error correction allows a QR code to be read even if part of it is damaged or obscured. Level L recovers 7% of data, M recovers 15%, Q recovers 25%, and H recovers 30%. Higher levels make the QR code denser but more resilient.
What is the maximum size of data a QR code can hold?▼
A QR code can store up to 4,296 alphanumeric characters or 7,089 numeric characters. For URLs and text, the practical limit is around 2,000-3,000 characters depending on the error correction level.
Should I use SVG or PNG format?▼
Use SVG for print materials and when you need the QR code at any size without quality loss (it's vector-based). Use PNG for digital use cases like websites, social media, and presentations where a fixed resolution is fine.
Is this QR code generator free?▼
Yes, completely free with no limits, watermarks, or signup required. QR codes are generated entirely in your browser — no data is sent to any server.
