2

3
Send it back
Tap Share and choose Mail. Reply to the person who sent it, with the signed PDF attached.
If they can't see your signature
Sometimes you sign, send it, and the other person says the signature line is blank. This happens when they open it on some Windows computers or Android phones. They do not always show a signature added with the iPhone's built-in tool.
eSign PDF locks the signature into the page before you send it (this is called flattening). Then it shows up on any computer or phone.
The free way
Your iPhone already has a tool called Markup. Tap the PDF in your email, tap the pen icon, tap +, then Add Signature. For a simple one-page form going to someone with an iPhone or Mac, that is often enough. Our guide on how to sign a PDF on iPhone shows each tap.
The easier way
eSign PDF lets you sign, date, and send back a PDF so it shows up on any device. $59.99 one-time (US). No account. Nothing is uploaded. Your file stays on your iPhone.
FAQ
Do I have to print it out to sign it?+
Usually no. You can sign the PDF on your iPhone and send it back. If the sender asks for ink on paper, do what they ask.
How do I send it back after I sign it?+
Tap the Share button and choose Mail. Reply to the original email so the signed PDF goes back to the right person.
The person said my signature is missing. What happened?+

$59.99 one-time (US). Other plans and local prices are in the App Store.
