Frequently Asked Questions (FAQs)
1. Do the generated QR codes expire?
No, these are static QR codes. The encoded text is embedded directly into the pixel structure, meaning they will work forever without expiry.
2. How does the logo affect scanning reliability?
QR codes have built-in error correction (we use High level 30% recovery) that allows central pixels to be covered. Keep your logo compact for maximum compatibility.
3. How does UTF-8 encoding work with this QR generator?
All input text is converted into standard UTF-8 byte streams. This ensures that non-ASCII characters like Vietnamese diacritics, Asian scripts, and emojis are decoded seamlessly by any modern QR code scanner or smartphone camera without character corruption.
