MEGA

MEGA is a New Zealand-based cloud storage and file hosting service, characterized by end-to-end encryption and large free storage capacity.

MEGA

Overview

MEGA (MEGA Limited) is a cloud storage and file hosting service provider headquartered in Auckland, New Zealand. Founded in 2013 by Kim Dotcom, MEGA prioritizes user data security and privacy, with its most notable feature being the provision of end-to-end encryption by default. Free users receive 20GB of basic storage, which can be expanded up to 16TB through paid plans. MEGA is accessible via web browsers, desktop applications (Windows, macOS, Linux), and mobile apps (iOS, Android), and supports file synchronization, backup, and sharing functions.

History and Background

MEGA was launched on January 19, 2013, as an alternative to Kim Dotcom's previous file hosting service, Megaupload, which was shut down by the U.S. Department of Justice in 2012. While Megaupload was closed due to copyright infringement issues, MEGA was designed from the outset as a legal service, minimizing legal risks by encrypting user data so that even the service provider cannot view the contents of users' files. In 2015, Kim Dotcom sold his stake in MEGA and stepped down from management, after which MEGA has operated under an independent management structure.

Technical Features

MEGA's core technology is an end-to-end encryption system combining RSA-2048 asymmetric encryption and AES-128 symmetric encryption. When a user uploads a file, it is encrypted in the browser or app before being transmitted to the server, so the MEGA server only stores encrypted data, and the decryption key is held solely by the user. This means MEGA cannot access user data and cannot provide it even in response to legal requests. Additionally, MEGA uses HTTPS for file transfers and supports two-factor authentication (2FA) to enhance account security.

Services and Pricing

MEGA offers 20GB of storage in its free plan, with paid plans consisting of Pro Lite (400GB, €4.99/month), Pro I (2TB, €9.99/month), Pro II (8TB, €19.99/month), and Pro III (16TB, €29.99/month). All paid plans include transfer quotas (traffic), with Pro III providing 12TB of transfer per month. MEGA also offers a Business plan with team collaboration features and a central management console. Key features of MEGA include file versioning, folder sharing, link creation (with password and expiration date settings), and chat functionality (MEGAchat).

Security and Privacy Controversies

While MEGA ensures high privacy through end-to-end encryption, it has faced criticism for potentially being exploited for the distribution of illegal content. Since MEGA cannot view user data, it cannot proactively block illegal files such as those involving copyright infringement or child pornography. In response, MEGA operates a policy of detecting illegal content and suspending accounts through a user reporting system and AI-based file hash analysis. In 2021, MEGA collaborated with New Zealand police to identify distributors of child sexual abuse material (CSAM).

User Experience

MEGA offers an intuitive web interface and desktop synchronization client, with relatively fast upload and download speeds for large files. Free users face transfer speed limits, while paid users can access higher bandwidth. The mobile app supports automatic photo backup and offline file access. However, some users note that end-to-end encryption limits file search functionality and that the complexity of sharing links is a drawback.

Latest Trends

As of 2024, MEGA is enhancing AI-based file management features. In late 2023, MEGA launched a beta service called 'MEGA AI,' testing image object recognition, document summarization, and automatic tag generation. In early 2024, MEGA's desktop app was updated to version 5.0, improving the UI and synchronization speed. As competition in the cloud storage market intensifies with Google Drive, Dropbox, and OneDrive, MEGA maintains its privacy-focused differentiation and strengthens GDPR-compliant marketing in the European market. In 2025, news emerged that MEGA is researching the introduction of post-quantum cryptography (PQC) in preparation for quantum computers.
