How to Sign a PDF on Your iPhone or iPad

You’ve received or need to send a PDF through email that must be signed and sent to the other party. If you’re working with the email on your iPhone or iPad, you can sign the document directly from your mobile device. This handy capability is possible due to the Markup feature. With iOS 13, you can use a variety of tools. In this post, we will look at the Signature Markup tool.

This is for iPhone/iPad or similar devices using iOS 13 or above
