Online scanner tool
Choose an image from your device or use a supported camera to check a saved QR code, screenshot, another screen, or printed proof. The scanner works in desktop browsers and on phones.
The code is read in your browser. The scanner uses BarcodeDetector when available and a local JavaScript decoder otherwise. Review the result before opening a link.
Local scanner
QR code scanner online
Read QR payloads from an uploaded image, PC, laptop, or camera without sending the file to QR Code Crafter.
Upload image
Use a screenshot, downloaded QR file, or exported QR artwork image.
Camera scan
Check a printed proof, laptop screen, poster, or package.
Scanning happens locally in your browser. Images and decoded payloads are not uploaded.
Key decisions
Read saved QR images
Upload a PNG, JPG, WebP, or screenshot of the final asset to verify the encoded payload after layout, compression, or resizing.
Scan from PC or laptop
Choose a screenshot or downloaded file, or use camera access to check another screen, a print proof, poster, or package.
Keep scans private
The image is processed in your browser. QR Code Crafter does not upload it or log the decoded QR content.
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 |
Online QR scanner workflows
Use the same scanner page for desktop QA, laptop reviews, and phone-camera checks before a QR code goes live.
Scan a QR code image
Upload a saved PNG, JPG, WebP, GIF, BMP, or screenshot when you need to decode a QR code from artwork, email, a PDF preview, or a design export.
Scan on a PC or laptop
Take a screenshot of the QR code on your computer, upload it to the scanner, and confirm the exact URL, text, WiFi, vCard, event, or payment payload.
Use camera scanning
Allow camera access when supported to test a printed proof, packaging sample, poster, table tent, or another screen from the expected scan distance.
Review links before opening
Decoded HTTP and HTTPS links can be opened after review, but the scanner keeps the raw payload visible so suspicious redirects can be checked first.
QR scanner preflight checklist
- Scan the final exported artwork, not only the source QR code image.
- On a PC or laptop, upload a screenshot or downloaded QR image to verify the exact payload.
- 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 from your PC or laptop.
- 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 processes the image in your browser, using its built-in QR detection when available or a local decoder otherwise. QR Code Crafter does not upload the image or log the decoded content.
What if native QR scanning is not available?
The scanner first tries the browser BarcodeDetector API, then uses a local JavaScript decoder if native QR detection is missing. Camera scanning still requires browser camera access.
Can I scan a QR code on a PC or laptop?
Yes. Save the QR code image or take a screenshot, upload it to the scanner, and review the decoded payload. Camera scanning may also work when the browser and device permit camera access.
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.
