Security and File Processing

Local document processing

All advertised tools read document data on your device using self-hosted libraries. No documents are transmitted to a remote converter. We validate file signatures, bound file bytes and page counts, and limit raster canvas dimensions. Encrypted files are rejected by modification tools.

Protect your originals

Local processing reduces document-transfer exposure but cannot eliminate browser bugs, malicious extensions or compromised devices. Keep your browser current and retain originals. These tools are not a secure redaction or certificate-signing service.

Hosting and reporting

Use HTTPS in production. Contact messages pass through the hosting mail system. Report issues through Contact without including sensitive documents. No security certification or legal compliance certification is claimed.
