Frequently asked questions
What is the difference between PNG and SVG?
PNG is a high-resolution raster image, ideal for print and social media. SVG is vector-based, scalable to any size without quality loss, ideal for large-format printing.
Does the QR code expire?
No. The generated QR code is static-it encodes the URL or text directly in the pattern. As long as the linked content exists (e.g., the website is online), the QR works forever.
Can I add my association's logo in the center?
Yes-upload your logo in the dedicated field. The logo covers about 15% of the QR code, but the built-in error correction (level H) ensures readability.
How many characters can I encode?
Up to 2,953 alphanumeric characters. For long URLs, use a URL shortener first. For vCards, fields are automatically optimized.
Is data sent to servers?
No. The QR is generated entirely in your browser via the qrcode.js library. No content is ever sent to our servers.
How do I test the generated QR?
Click "Test QR" in the preview panel or scan the QR with your phone camera. We recommend testing before printing.
