For this article, I'll look specifically at Markup's signature tool.
You can use the different Markup tools on PDFs and image files. With iOS 13 and iPadOS 13, it sports a new interface, offers a variety of palette tools, and supports Messages and Photos as well as Mail. Introduced with iOS 10 in 2016, the Markup feature has evolved over the years.
That handy capability is possible due to the Markup feature in iOS and iPadOS. Sure, you can do this on your computer with Adobe Reader, but if your PC isn't handy and you're working with the email on your iPhone or iPad, you can sign the document directly from your mobile device. You've received or need to send a PDF or other document through email that must be signed and sent to the other party.
