OnionShare

OnionShare is an open-source tool that lets you securely and anonymously share a file of any size. It works by starting a web server accessible as a Tor onion service, with an unguessable URL that you can share with the recipients to download or send files.

Key Features:

• Share files of any size anonymously
• No file size limits
• Works through Tor for anonymity
• Temporary sharing - links expire after use
• No third-party servers involved
• Receive files anonymously as well
• Self-hosted - runs on your own computer

Use Cases: Secure file sharing for journalists, activists, or anyone who needs anonymous file transfer.
