Frequently Asked Questions
What types of QR codes can this tester decode?
Our tester can decode all standard QR code formats including URLs, plain text, WiFi credentials (SSID/password), vCard contacts, email addresses, phone numbers, SMS messages, calendar events, cryptocurrency addresses, and geographic locations.
Is this QR code tester free?
Yes, completely free with no limits. There is no account required, no watermarks, and no daily scan limits. Upload as many QR codes as you need to test.
Can I test QR codes from my camera?
Yes! Click the camera button to use your device camera for live scanning. This works on phones, tablets, and laptops with webcams. Grant camera permission when prompted.
Why is my QR code not scanning?
Common reasons include: the image is too small or blurry, the QR code is damaged or partially obscured, the colors have low contrast, or the quiet zone (white border) is missing. Try uploading a higher resolution image.
Can I test a QR code before printing it?
Absolutely — that is one of the most popular uses for this tool. After generating a QR code with Nofolo, download it and upload it here to verify the encoded data matches what you expect before printing.
Does this tool store my QR code images?
No. All processing happens locally in your browser. Your images are never uploaded to any server. Once you leave the page, the data is gone.
