Scanner tool
Scanner and reader searches usually need a working tool, not only advice. QR Code Crafter now includes a browser-local scanner for checking QR codes from exported artwork, screenshots, and camera input.
The scanner uses the browser BarcodeDetector API when available. Images stay on the device, and decoded links are shown plainly so you can copy or open trusted HTTP and HTTPS destinations.
Local scanner
Scan a QR code
Read QR payloads from an uploaded image or camera without sending the file to QR Code Crafter.
Upload image
Use a screenshot or exported QR artwork image.
Camera scan
Check a printed proof, screen, poster, or package.
Scanning happens locally in your browser. Images and decoded payloads are not uploaded.
Key decisions
Read exported artwork
Upload a PNG, JPG, WebP, or screenshot of the final asset to verify the encoded payload after layout, compression, or resizing.
Use camera checks
Scan a printed proof or screen display with the device camera when the browser supports native QR detection.
Keep scans private
Detection happens in the browser. QR Code Crafter does not upload the image or log the decoded QR payload.
QR scanner checks before publishing
| Check | What to verify | Why it matters |
|---|---|---|
| Payload | The decoded text, URL, WiFi, vCard, event, or payment payload is exact | Tiny typos can survive visual review and break the final scan flow |
| Final export | The QR code still scans after export from Canva, Adobe, PDF, or print artwork | Layout software can crop, compress, or resize a code after generation |
| Real device | At least one phone camera can read the final proof from the expected distance | A code that scans from the source file may still fail on a wall, table tent, or package |
QR scanner preflight checklist
- Scan the final exported artwork, not only the source QR code image.
- Confirm the decoded payload is exactly the URL, WiFi, contact, event, payment, or text value you intended.
- Check the printed proof from the expected distance and lighting conditions.
- Use a second phone camera before sending high-volume packaging, signage, or menus to production.
How to use the QR code scanner
- 1
Upload an image
Choose a QR code image, screenshot, exported PDF preview image, or campaign artwork saved as an image.
- 2
Scan with camera
Allow camera access when supported and point the camera at a printed proof, screen, poster, or package.
- 3
Review the decoded payload
Copy the result or open trusted HTTP and HTTPS URLs after confirming the destination is expected.
Frequently asked questions
Are uploaded QR code images sent to a server?
No. The scanner reads images locally in the browser when native QR detection is available. QR Code Crafter does not upload the image or decoded payload.
Why does the QR scanner say my browser is unsupported?
The scanner relies on the browser BarcodeDetector API. If your browser does not expose QR detection, use a modern Chromium-based browser or scan with your phone camera.
Should I open every decoded QR link?
No. Review the decoded destination first and only open URLs you trust. The scanner only provides an open button for HTTP and HTTPS links.
