A TransferThing link
Drop the file here, paste the link into your Yahoo mail. Up to 5 GB, without an account for you or the recipient.
A cloud drive link
Put the file on Google Drive, OneDrive or Dropbox and paste the share link. It uses your storage there; check who can open it.
Zip or split
A .zip barely shrinks videos, photos or PDFs. Several e-mails work, but your recipient has to put everything back together.
