Why local processing matters
When you process documents locally, file contents are not transferred to a third-party processing service.
For sensitive paperwork, this reduces avoidable transfer exposure and supports a cleaner compliance posture.
Quality checks before sending
Open the output in a separate PDF viewer and check first page, last page, and any critical attachment pages.
If the file is being uploaded to a portal, verify the accepted size and naming format before final upload.
When to repeat the workflow
Repeat the process when source documents change or when portal limits are updated.
Keep a simple processing note with date and version if the document is part of a recurring submission routine.
