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

If you receive an attachment that you need to sign and send back to the sender, the process is similar.

2. Tap the Markup icon in the upper right (the one that resumbles a pen tip)
3. Tap the “+” icon on the Markup toolbar at bottom righ hand corner and select Signature. Your Signature will automatically appear if you already created it via Markup.
4. Tap your Signature, position and resize it accordingly
5. When finished, tap Done
6, Tap New Message or Reply All and send the signed document back to the sender. For demonstration purposes, I just placed my Signature again, this time in lower right hand corner. Refer to below image:
