易云盘 is a cloud storage brand focused on fast, secure access to files through direct links. Its service lets individuals, teams, and businesses store, stream, download, and share content without requiring transcoding or an intermediate proxy layer. Direct links support video formats such as MP4, WebM, and MKV; audio including MP3, FLAC, and WAV; and images including WebP, JPG, PNG, and GIF. Users can share files and folders with passwords, expiration dates, and access controls, while security features include two-factor authentication, encrypted transfers, IP and referrer restrictions, and token-based file authentication.

The platform also offers Amazon S3-compatible uploads, WebDAV access, offline downloads from URLs and torrent sources, and hash-based deduplication for faster transfers. Traffic statistics help users monitor bandwidth and activity. Daily check-ins can earn additional storage, with the site advertising up to 500GB in bonus space. Plans range from a free tier for personal projects to professional, business, and custom enterprise options, with varying storage and bandwidth allowances. Custom domains, support, and auto SSL are available on selected plans.
