Read Security GuideFrequently Asked Questions
Everything you need to know about QR code validation.
How does the QR code validator work?
Upload any QR code image or check it via camera. The system reads and decodes the image client-side, parses the underlying text schema, runs a domain risk-check evaluation, and measures contrast alignment.
Is my uploaded QR code sent to any servers?
No. We prioritize your security. All image reading, pre-processing, and visual diagnostics are executed 100% inside your local browser. Your data never leaves your machine.
What security threats can the validator detect?
Our checker scans the underlying URL for unencrypted HTTP setups, known phishing domains, typosquatting domains (e.g. g00gle.com), subdomain abuse, non-standard ports, and hidden redirection paths.
Can I validate QR codes created by other generators?
Yes, our utility works universally. You can upload or scan any QR code image regardless of the builder or software used to construct it.
