How it works
Complete the job in three clear steps
- Upload a clear image or grant camera access.
- Place the complete QR code inside the preview area.
- Review decoded content and inspect any destination before choosing to open it.
Free local QR scanner
QR Code Scanner
Scan QR codes from an uploaded image or camera with local jsQR and ZXing decoding, then preview the decoded content safely.
Free to use Uploaded images and camera frames are decoded locally and are not sent to Lucaden.

Important
Check the result before relying on it
Scan-test generated codes before printing or distribution. A generated barcode does not register identifier ownership, and decoded external links should be checked before opening.
Practical details
What this Lucaden tool does
Uploaded QR images are decoded with the pinned jsQR pixel scanner first, with ZXing retained as a local fallback and camera engine.
Decoded links are shown for inspection and are never opened automatically.
Included capabilities
- jsQR uploaded-image decoding
- ZXing image fallback
- Local camera scanning
- Safe link preview
Useful for
- Read a QR from a screenshot

Questions
About this tool
Will the scanner automatically open a link?
No. It shows the decoded content and destination host first, leaving the decision to open it with you.
Why can a scan fail?
Blur, glare, low contrast, missing corners, or a QR that is too small in the image can prevent reliable decoding.
