"QR library failed to load"
- Check your internet connection (first load requires CDN)
- Refresh the page
- Try a different browser
- Check browser console for network errors
Generated QR code won't scan
- Increase error correction level (try Q or H)
- Use a simpler/shorter input
- Ensure sufficient contrast (dark QR on light background)
- Use a dedicated QR scanner app (some camera apps are unreliable)
Background image looks distorted
- Use a square or near-square image
- Try a different image
- File must be under 5MB
- Supported formats: PNG, JPG, WebP, GIF
Large resolution export is slow
- 2048×2048 rendering takes a few seconds
- Try 1024×1024 for faster export
- Complex backgrounds slow down rendering
