Privacy and cleanup

Server-based tools use isolated temporary job folders. Outputs are streamed back and scheduled for deletion. The local reader never uploads your PDF.

Upload limits

The backend uses your configured production limits.

Large documents

OCR, flattening, comparison, and image conversion are CPU-heavy. Start with a smaller document when validating a new deployment.
