Question 1

What can I create with QR & Barcode Hub?

Accepted Answer

You can generate customizable QR codes and barcodes, and scan existing ones using your webcam or an uploaded image file.

Question 2

Does scanning a code send the image to a server?

Accepted Answer

No — both webcam and file-upload scanning are processed locally in your browser, so the image never leaves your device.

Question 3

Can I customize a generated QR code's appearance?

Accepted Answer

Yes, typical options include size, colors, and error-correction level, though adding a logo or heavy styling can reduce scannability if the code becomes too cluttered.

Question 4

Why won't my webcam scan a code?

Accepted Answer

Webcam scanning needs camera permission granted to the site plus a well-lit, in-focus, roughly head-on view of the code — blurry or steeply angled shots often fail to decode.

Question 5

Is this tool free to use?

Accepted Answer

Yes, generating and scanning codes is free with no account required.
