Confirm that fields, entered values, and required controls remain usable in the final PDF. Start with the destination requirements, work from a copy, and inspect the downloaded result. It may affect features depending on the source and tool, so test fields and values in the exact output. This keeps the workflow reversible and gives you a concrete final file to review before the next step.

Prepare the fillable PDF before processing

Confirm that fields, entered values, and required controls remain usable in the final PDF. Record the source filename, size, page count, and any destination rules first. PDFStay's normal fillable PDF workflow is designed to process the PDF in the current browser session rather than upload it to PDFStay servers. Your own organization or destination policy remains the final authority.1, 2
