Send files from Files on iPad
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.
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.
To send files from Files, you can also use Split View or Slide Over to open Mail or Messages, select one or more items in Files, then drag your selection into a message.
Tip: If the files or folders 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.
