Frequently Asked Questions

Will this tool automatically open the URL in the QR code?

No. The tool strictly extracts and displays the raw text payload, protecting you from automatically visiting malicious sites.

What image formats are supported?

You can upload standard web image formats such as PNG, JPEG, and WebP.

Does my image get uploaded to a server?

No. The image processing and decoding occur entirely in your browser. Your files never leave your device.

What if the QR code is slightly blurry or damaged?
