Onion Share is an open source utility which is used to share files of any size over the TOR network securely and anonymously. It is so secure and so simple to use, just drag your file and drop it to the OnionShare. It will then generate a long random URL which can be used by the recipient to download the file over the TOR network using the TOR browser.
