Frequently Asked Questions

Do QR images or camera frames upload to the server?

No. Uploaded images, clipboard images, and live camera scans are decoded locally in your browser. The decoded content is not sent to the 100tools server.

What QR code contents can it recognize?

The reader decodes standard QR text and labels common payloads such as URLs, WiFi credentials, email, phone, and SMS. Other payloads are shown as plain text with one-click copy.

What should I do if camera scanning fails?

Check that the browser has camera permission and keep the full QR code clear inside the viewfinder. Reflections, blur, shadows, cropped corners, or very small codes can reduce detection accuracy.
