Yahoo Mail lets you attach files to emails to send them to your recipients. Images, spreadsheets, or PDFs—you can attach any file to an email message you write to your Yahoo Mail account. The maximum message size limit is 25MB, which includes all the elements and text of the email and its encoding.

For large attachments—those exceeding 25MB in size—Yahoo Mail suggests using Dropbox or another large-file transfer service. You upload large files to a company's server, and it sends an email or provides a link for you to send in an email to your recipient. The recipient downloads the file directly from the transfer service website.
