WeTransfer is a cloud-based file transfer service that allows users to send and receive large files up to 2GB for free. The sender simply uploads the file to WeTransfer's servers and specifies the recipient's email address. The recipient then receives an email with a download link to retrieve the file. WeTransfer also offers a paid subscription service called WeTransfer Pro, which allows users to send up to 20GB of files and provides additional features such as password protection, customizable branding, and storage.
