A private Dropbox alternative
Dropbox holds your files — and the keys. Marsdrop encrypts everything in your browser, so the server can't read what you share. No account, free, with self-destructing links.
Encrypted in your browser, then uploaded. Share a link they open anytime.

Dropbox alternative FAQ
Is Marsdrop a good Dropbox alternative?
If your goal is privacy, yes. Dropbox stores your files and holds the keys, so it can technically read them. Marsdrop encrypts files in your browser and never receives the key, so no one — not even Marsdrop — can read your files.
How is Marsdrop different from Dropbox?
Dropbox is cloud storage that also shares files; it's encrypted on Dropbox's servers but Dropbox holds the keys. Marsdrop is built only for private sharing: zero-knowledge encryption in your browser, no account, and links that auto-expire.
Can Dropbox read my files?
Dropbox encrypts files at rest, but it controls the encryption keys, which means it can technically access your file contents (for example, to scan or comply with legal requests). With Marsdrop, the key never leaves the link, so the contents stay unreadable to the service.
Is this Dropbox alternative free?
Yes. Marsdrop is free, needs no account, and shares files via encrypted, self-destructing links.
