Send files from Files on iPhone
You can send a copy of any file in the Files app to others. If you have a document you want to send that isn’t digitized, you can scan it with Files first.
Send a file
Touch and hold the file, then tap Share.
Tip: To send a smaller version of the file, tap Compress before you tap Share. Then touch and hold the compressed version of the file (identified as a zip file), and tap Share.
Choose an option for sending (for example, AirDrop, Messages, or Mail), then tap Send.
Scan a document
Tap at the top of the Browse screen, then tap Scan Documents.
Tip: If the files you want to share are stored in iCloud Drive, you can invite others to view or edit their contents—you don’t need to send them copies.
