Frequently asked questions
Does it create reusable AcroForm fields?
The current workflow prints entered values into the PDF; it is not a full form-authoring replacement.
Can I correct a detected field?
Yes. Always review and adjust field positions before export.
PDFPerch processes files locally unless this guide explicitly identifies a cloud-dependent feature. Always keep an original copy and verify critical output before submission, printing, signing, or accounting use.
