No QR code handy?
Nothing is uploaded or stored — it all runs on your device.
The decoded content appears here — with type, safety check and actions.

One engine, the full lifecycle: Create a code that's verified to scan, Rescue a damaged one, and Verify quality — all on-device with a real decoder (jsQR) plus image processing (grayscale, contrast stretch, Otsu threshold, sharpening). Deep AI reconstruction of severely damaged codes, AI backgrounds, and the industrial verification API are the paid tiers.

FAQ

Scanning QR codes — quick answers

How do I scan a QR code without an app?
Right here in your browser: tap “Start camera”, allow camera access and hold the code inside the frame. The content appears instantly — no app, no signup, free.
Can I read a QR code from a photo or screenshot?
Yes — upload the image or drag & drop it into the scanner. Semacode reads the code from JPG, PNG or HEIC and shows you the content.
What if the QR code doesn’t work or is damaged?
Semacode automatically enhances the image (contrast, sharpness, threshold). If that’s not enough, the AI repair reconstructs damaged codes and recovers the content — switch to the Rescue tab.
Is the QR scanner safe and free?
Yes. Scanning runs entirely on your device — nothing is uploaded. Before you open a link, we check it for common phishing patterns. The scanner is free.
