Technical Considerations & Limits
- • Zero-transmission privacy: data processing runs strictly client-side inside your browser environment. Source code, secrets, and payloads are never dispatched to external servers or telemetry systems.
- • Processing speed depends entirely on your device hardware (CPU & available RAM). Extremely large files (>200MB) may exceed browser memory limits.
