FAQ
Questions, answered.
Can I fill form fields with this tool?
Interactive form-field editing lands in Prompt 4D. Today, use it to add signatures, dated approvals, and text stamps to any PDF — fillable or flat.
Is this a legally-binding digital signature?
Sign PDF adds a visible signature image, name, date, reason, and location. For long-term validation with cryptographic certificates (PAdES, DocuSign, eIDAS), pair this with a certificate-issuance provider or wait for the upcoming Digital Certificate Signatures release.
Can I sign every page at once?
Yes — toggle “Apply to every page” to stamp the signature on all pages.
