About
Tap the line. Your saved signature snaps onto it, at the right size.
An email arrives at 9:01 with a lease to sign. Tap the PDF, tap Share, tap Sign PDF. Tap the line. Done opens the share sheet: choose WhatsApp and the chat, attach it to an email, or save it to Files. Signed at 9:01.
HOW IT WORKS
- Draw your signature and initials once, or type them. They stay on this iPhone.
- Open almost any PDF: from Mail, WhatsApp, Messages or Files through the share sheet, from Files inside the app, or scan paper with the camera.
- Tap Sign, then the line: the signature snaps onto it at a size that fits. Initials work the same way.
- Text: one tap for today's date, your name, email, phone or address, or type anything. Check: tick a box.
- Everything you place is selected right away: drag it to move it, drag a dot to make it bigger or smaller, or remove it. Undo takes back the last step.
- Tap Done. The signed copy is flattened and the share sheet opens: WhatsApp, Mail, Files, print.
NO ACCOUNT. YOUR DOCUMENTS STAY ON YOUR IPHONE.
The app never uploads your documents or your signature. No sign-up, no envelope. It works offline.
WHAT IS FREE, WHAT IS PRO
Your first 3 signed documents are free, with no watermark. The sample lease doesn't count.
Pro signs every document after that:
- Pro Yearly, with a 1-week free trial
- Pro Monthly
- Pro Lifetime, one payment
Prices are shown in the app in your currency.
Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period; your account is charged for renewal within 24 hours before the end of the period. Any unused part of a free trial is forfeited when you buy a subscription. Manage or cancel in Settings > [your name] > Subscriptions.
Sign PDF places your own signature on a document, as signing the paper by hand would. It is not a certified digital-signature service, and it does not sign PDFs that someone has already signed digitally.
