What We Check

Every Aspect of Your QR Code

QRastra's validator performs a comprehensive analysis of your QR code to catch issues before they become problems.

Encoding Analysis

Verifies that your content is properly encoded using the correct character set (UTF-8, ISO-8859-1, etc.) for optimal scanner compatibility.

Error Correction Level

Checks if the error correction level (L, M, Q, H) is appropriate for your use case. Higher levels provide better damage recovery.

URL Safety Scan

Detects potentially risky or malicious URLs, phishing attempts, and suspicious domains before they're encoded.
