Will my files be uploaded to your servers?

No. Parsing, flattening, and export happen in your browser, reducing transfer risk for sensitive documents.

Will flattening change document appearance?

Visual layout usually stays the same. The key change is that form controls are removed so values cannot be edited.

Why do I see no form fields detected?

Some PDFs are not interactive forms. Export still works, but visual differences may be limited.

What if one file fails in a batch?

Failures are tracked per file. Successful files can still be exported while failed files can be retried separately.

Can I add more files in the workbench?

Yes. You can append files during processing, which is useful for late-arriving documents.

Are output names suitable for archive workflows?

Yes. Output names preserve source traceability and flatten indicators for legal or audit indexing.
