Frequently Asked Questions
Common questions about QR code scanning, security, and image troubleshooting.
Why won't my image decode?
For the algorithm to successfully decode the image, the QR code must have clear contrast (usually black on white), not be cut off at the edges, and be reasonably sharp. If your image is very blurry or low-resolution, the tool cannot map the data pixels.
Is it dangerous to scan random QR codes?
Yes, scanning codes found in public places with your phone can be dangerous because they might force your device to navigate to a phishing site or trigger a malicious download. Using our online reader is a safe middle-step to reveal the URL before deciding to visit it.
What kind of data can be hidden in a QR code?
QR codes can hold almost any type of alphanumeric data. The most common are Website URLs, plain text messages, VCard contact information, Wi-Fi network credentials, SMS drafts, and email templates.
Are my uploaded images saved by your site?
Absolutely not. Our application operates strictly locally via HTML5 File APIs. When you drop an image into the upload box, it is loaded directly into your browser's memory. No network requests are made to send your image to a server.
