eSign PDF in one paragraph

eSign PDF is an iPhone and iPad app for signing and filling PDFs you received — by email, Files, or a scan. It flattens the signed file so the signature shows on Windows and Android, works offline, needs no account, and costs $59.99 one-time (US). It does not send documents for other people to sign; for that, DocuSign Personal is $11 a month billed annually ($132 a year, 5 envelopes a month).

Ready to go paperless?

Sign your first document in under a minute. No printer needed. $59.99 one-time (US).
