Mega is a cloud storage and file hosting service that allows users to store and share files online. Founded in 2013 by Kim Dotcom, it offers a generous amount of free storage space, with options for paid plans that provide additional features and capacity. The service emphasizes privacy and security, using end-to-end encryption to protect user data. This means that only the user has access to their files, making it a popular choice for those concerned about data security and privacy in the digital age.
