FAQ
Is my file safe?
Files are transferred over an encrypted channel, automatically deleted within 24 hours, and never used for AI training.
Are there any limits?
Requires the server-side PDFBox Preflight command.
Is the protection strong enough?
Files are transferred over an encrypted channel to the server for validation, automatically deleted within 24 hours, and never used for AI training. The process strictly verifies ISO 19005 compliance without modifying your file.
Can I process multiple files in bulk?
A single tool page handles one task at a time; for bulk work use the Batch Processing workflow and add this tool as a step to run a whole set at once.
Is the processed file still editable?
This tool only generates a compliance report and does not modify your original PDF. Your original file remains untouched and fully usable, and you can review or download the report independently.
