Frequently Asked Questions (FAQ)
Can I scan a QR code from a screenshot without a camera?
Yes! Drag and drop any image or paste a screenshot from your clipboard to decode the QR code instantly.
Is camera permission requested safely?
Yes. The browser requests standard permission for the video feed. Video frames are analyzed locally in canvas memory and never transmitted anywhere.
What types of payloads can it decode?
It decodes web URLs, plain text, Wi-Fi configurations (WPA/WPA2), SMS/Email templates, and vCard contact cards.
Does it automatically open the scanned link?
No. For your security against phishing, OmniTool Hub displays the decoded URL first so you can inspect it before choosing to visit.
