Send big files up to 5GB securely, fast, and free
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.
AES-256 client-side encryption means files are encrypted on your device before upload, and Tresorit never sees the decryption key.
Send a single file or folder up to 5GB in size — enough for most video, archive, and dataset transfers.
Add an optional password to any share link so only recipients with the password can download.
Set an expiry date on every link; files and metadata are permanently removed 14 days after expiry.
Get email alerts when recipients open or download your shared files.
Instantly revoke access to any share link, even after it has been distributed.
Anyone can send files without signing up — just drop a file in the browser and share the link.
Lawyers, accountants, and consultants can send contracts, tax returns, or NDAs with end-to-end encryption and password gates instead of unsecured email attachments.
Designers, video editors, and photographers can ship multi-gigabyte raw files or project bundles without needing a paid WeTransfer subscription.
Anyone can send medical records, identity documents, or financial paperwork to family or professionals without leaving a copy on a cloud provider.
A free, no-account tool for one-off secure file transfers between organizations where setting up a shared drive is overkill.
