What image formats are supported for scanning?
The scanner supports common image formats including PNG, JPG, JPEG, GIF, and WebP. You can upload photos taken with your phone, screenshots, or any image file containing a QR code.
Can I customize the appearance of generated QR codes?
Currently, you can adjust the size of generated QR codes from 128px to 512px. The codes use a standard black-on-white color scheme for maximum compatibility with scanners.
Why might QR code scanning sometimes fail?
Scanning accuracy depends on image quality, lighting, and QR code clarity. Ensure the QR code is clearly visible, not distorted, and has good contrast. Higher resolution images generally scan more reliably.
Are there any limits on content length?
QR codes have natural capacity limits based on error correction level and content type. For optimal compatibility, keep text under 300 characters, though longer content may work depending on the scanner.
