BY DESIGN.
NOT BY CLOUD.
BY PDF is a browser-integrated utility for secure document handling where data stays within your physical control.
Execution
Documents are processed in isolated browser memory (RAM) via Client-Side Logic. No server-side runtime is engaged.
Integrity
All assets are served via Cloudflare Global Edge. Conversion is performed on the user's hardware to eliminate data transit risks.
Persistence
Zero-Knowledge Architecture. We do not maintain databases, storage buckets, or tracking identifiers. Session data is volatile.
Technical Reality
Traditional "Cloud" converters act as a bridge, requiring your sensitive data to be transmitted to third-party servers. This creates a permanent vulnerability in your data chain.
BY PDF solves this by moving the logic to the user. By utilizing modern browser capabilities, we generate PDF Blobs (Binary Large Objects) directly on your device. The result is instant, private, and mathematically secure.
