With Markup in iOS 14 (and versions back to iOS 12), you can edit screenshots and photos, select different opacity and font thickness, and even add a signature to a PDF document. Here’s how to use it in Messages:
° Open Messages and tap the compose button to start a new conversation. Or go to an existing conversation.
° Tap the Photos button and select a photo.
° Tap the photo in the message, then tap Markup. From here, you can add a sketch to the photo, or tap the plus (+) button for other Markup options.
° Tap Save, then tap Done.
° Tap the blue arrow to send.
(This how-to is based on my experiences and info on Apple’s support pages — where the images sometimes come from.)
