How to sign documents on your iPhone.


Download Acrobat from the app store on your iPhone to get started. Then follow these simple steps: 





Open a PDF file in the Acrobat mobile app. 





Tap the pencil icon in the lower right corner of your screen.





Select Fill & Sign.





From the available options, tap the Draw icon (which looks like a fountain pen).





Select Create Signature.





From the options, select Draw and use your finger (or an Apple pencil or other stylus) to write your signature.





Click Done to save your digital signature for future use.



Now you can move and resize your digital signature to fit anywhere on the document, all within the app.

This same process can be used to sign documents on an iPad, on an iPod Touch, or even with the trackpad and cursor on a Mac desktop.

If you see changes that need to be made in a PDF document before you sign, there’s no need to collect screenshots of the issues and hop on the phone. Use markup features in the Acrobat app to note them on the document itself with these steps: 





Once your document is open in the Acrobat mobile app, tap the pencil icon in the lower right corner of your screen.





Select Comment.





With the available markup tool options, you can use your fingers or a stylus to highlight, strike through, or underline text. You can also add notes and comments or draw and erase handwritten notes, arrows, circles, etc.





When finished, click Done in the upper left corner of the screen.





Select the ellipsis icon in the top right of the screen and choose Save to Document Cloud to make the notes accessible to everyone who has access to the document.
