Frequently Asked Questions
QWhat data can I encode in a QR code?
You can encode any text up to several hundred characters, including URLs, plain text, WiFi credentials (SSID, password, encryption type), and vCard contact information.
QWhat is error correction and which level should I choose?
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%. Use H for printed materials that may get dirty or partially covered.
QPNG or SVG — which format should I download?
Download SVG for print materials since it scales to any size without quality loss. Download PNG when you need a raster image for web embedding or sharing on social media.
QIs my data sent to a server?
No. The QR code is generated entirely in your browser using JavaScript. Nothing you enter is transmitted to any server.
