Frequently Asked Questions

Use caution with sensitive data. QR codes are readable by anyone with a scanner. Only convert non-sensitive environment variables or display QR codes temporarily in secure environments. Consider masking sensitive values.

QR codes can hold up to 4,296 characters. Most .env files fit comfortably, but large configuration files may need to be split into smaller sections or have comments removed.

Yes. The QR code contains your .env file as exact text. When scanned, you get back the same environment variables with identical formatting, including comments and empty lines.

Use any QR code scanner app on your phone. The scanned result will be your environment variables as text, which you can save as a .env file or copy into your development environment.

Yes. Comments (lines starting with #) are preserved in the QR code along with your environment variables, maintaining documentation and context from the original file.

All standard .env formats are supported: KEY=value pairs, quoted values, multi-line values, exports, and comments. The converter preserves the exact format of your environment file.

No. All processing happens locally in your browser using JavaScript. Your environment variables never leave your device, ensuring complete privacy for sensitive configuration data.

For sensitive data like API keys or passwords, consider masking values (e.g., API_KEY=***MASKED***) or only include non-sensitive configuration variables in the QR code conversion.

Yes. Docker-compose .env files, Kubernetes config files, and other container environment files work perfectly. The QR code preserves all variable declarations for easy deployment setup.

Scan the QR code with any scanner app to get the environment variables as text, then save that text to a file with a .env extension. All variables and formatting will be identical.

Special characters, spaces, and escape sequences in environment variable values are properly preserved in the QR code, maintaining the exact configuration needed for your application.

Yes, but exercise caution. QR codes work well for non-sensitive CI/CD variables like feature flags or environment names. Avoid including secrets, tokens, or credentials in QR code conversions.
