Often, certain files cannot be sent regularly via email due to file size restrictions. WeTransfer addresses this problem. WeTransfer is a web-based service provider that allows users to send large files up to 2GB via email for free. Without account registration, users can upload files, and end users are notified by email when the files are ready for download. WeTransfer monetizes on this concept by showing users high quality photo advertisements during uploading and downloading. The firm also offers a subscription-based service for larger files and cloud space where these files can be saved.
