QR Code Decoder FAQ
Is the QR code decoder free?
Yes, completely free. There is no registration, no app download and no usage limits - you can decode as many QR codes as you need.
Can I read a QR code from a screenshot?
Yes. Simply upload any screenshot or photo that contains a QR code and it will be decoded instantly.
Is my image uploaded to a server?
No. The QR code is decoded entirely in your browser using JavaScript, so your image never leaves your device.
Why is no QR code detected in my image?
Common reasons are blurry or low-resolution images, poor lighting, heavy cropping, or a very small QR code. Try a clearer, well-lit image where the QR code fills a good portion of the frame.
What type of data can the decoder read?
The decoder can read URLs, plain text and any content encoded in a standard QR code, including Wi-Fi credentials, contact details, email addresses and more.
