About Tresorit Send
Tresorit Send is a free, end-to-end encrypted file transfer service from Swiss privacy company Tresorit. It lets anyone share files up to 5GB without creating an account, using AES-256 client-side encryption with password protection, link expiration, and revocable share links.
Pros & Cons
Pros
- Strong AES-256 end-to-end encryption with zero-knowledge architecture

- Generous 5GB per-transfer limit for a free tool
- Password protection, expiration, and revocation built in
- Swiss jurisdiction and independently audited security
Key Features
End-to-End Encryption
AES-256 client-side encryption means files are encrypted on your device before upload, and Tresorit never sees the decryption key.
5GB File Transfers
Send a single file or folder up to 5GB in size — enough for most video, archive, and dataset transfers.
Password Protection
Add an optional password to any share link so only recipients with the password can download.
Link Expiration
Set an expiry date on every link; files and metadata are permanently removed 14 days after expiry.
Download Notifications
Get email alerts when recipients open or download your shared files.
Link Revocation
Instantly revoke access to any share link, even after it has been distributed.
No Account Required
Anyone can send files without signing up — just drop a file in the browser and share the link.

Best For
Sharing confidential documents with clients
Lawyers, accountants, and consultants can send contracts, tax returns, or NDAs with end-to-end encryption and password gates instead of unsecured email attachments.
Sending large creative assets
Designers, video editors, and photographers can ship multi-gigabyte raw files or project bundles without needing a paid WeTransfer subscription.
Transferring sensitive personal files
Anyone can send medical records, identity documents, or financial paperwork to family or professionals without leaving a copy on a cloud provider.
Ad-hoc secure B2B handoffs
A free, no-account tool for one-off secure file transfers between organizations where setting up a shared drive is overkill.
