Tips & Troubleshooting
- Choose Error Correction Level H (30%) if you plan to place a logo in the center or if the code might get scratched on printed surfaces.
- Always download the SVG vector format for large-scale professional printing; use PNG for digital displays and social media.
- Ensure strong visual contrast between the foreground code color and background (e.g. dark code on a white background).
- Always test-scan the generated QR code with both iPhone and Android cameras before sending materials to the printer.
Frequently Asked Questions
Do generated QR codes expire?
No. Static QR codes encode your data directly into the pixel matrix and will work forever without relying on redirection servers or subscriptions.
How does the Wi-Fi QR code work?
Scanning a Wi-Fi QR code with an iPhone or Android smartphone automatically connects the device to the network without typing passwords.
What is Error Correction Level (ECC)?
Error correction allows QR codes to remain readable even if partially damaged, smudged, or obstructed (Level L: 7%, M: 15%, Q: 25%, H: 30% recovery capacity).
Can I download vector SVG QR codes for printing?
Yes! Vector SVG downloads scale to any billboard or packaging size without pixelation or quality loss.
Is my QR data sent to your servers?
No, all QR matrix generation and graphics rendering execute 100% locally in your web browser.
Is there any scan limit or watermark?
Daily Tools QR codes are 100% free with unlimited scans and zero watermarks.
