Files are encrypted on your device before they ever reach Mega’s servers.
The keyword "mega.nz links" is heavily associated with piracy, and for good reason. Because MEGA offers generous storage (20 GB free) and strong encryption, it has historically been used to share copyrighted movies, software, and music.
When someone clicks on the mega.nz link, they are directed to the file or folder you've shared. If the link is for a file, the recipient can download it directly. If it's for a folder, they can view all the contents of the folder and download files as needed.
: MEGA’s Transparency Report clarifies that their terms of service strictly prohibit copyright infringement. While they cannot see your encrypted files, they will disable public links if a copyright holder reports them. Troubleshooting Common Issues
When you upload a file to MEGA, your browser or app encrypts the data before it leaves your device. The server receives gibberish. To decrypt that file, the recipient needs a key. That key is embedded directly within the MEGA link.
