FAQ
Which images can be decoded?
Clear complete QR codes in screenshots or photos work best; heavy compression, blur or partial occlusion reduce success rates.
Is decoding safe? Will links auto-open?
Only the decoded text is shown, nothing opens automatically — verify link authenticity first to avoid malicious QR codes.
Is my image uploaded?
No, the decoding algorithm runs entirely in your browser.
