Frequently asked questions
Are codes or scanned images uploaded?
No. Generation and image decoding run in your browser. Camera access is requested only when you choose it.
Which barcode formats are supported?
The generator supports Code 128, Code 39, EAN-13, EAN-8, and UPC-A with format-specific validation.
What does QR error correction change?
Higher levels can recover from more damage but produce denser symbols. Test the final size and surface with real scanners.
Is opening a scanned link automatically safe?
No. The editor previews the exact content and flags some risky patterns, but you should still verify the destination before opening it.
