Send files only your recipient can open
End-to-end encrypted file transfer in your browser. Files are locked on your device before upload, so only people with your link can open them, not even us.
Two Things You Can Do
1. Request Files Privately
Create an end-to-end encrypted drop portal. Specify the exact documents you require, restrict allowed formats (such as PDF, PNG, or JPG), set an expiration, and share a single link. Files are locked in the sender's browser before upload. Only you hold the key to open them.
2. Send Files or Notes
Send files, folders, or private notes. Everything is locked on your device before it uploads, and only the people with your link can open it.
How end-to-end encrypted file transfer works
Files and secret notes are locked on your device before upload, so only people with your link can open them.
Step 1: Choose files, folders, or a note
Pick what you want to send. Add optional passwords, download limits, or auto-delete after a set time.
Step 2: Lock on your device
Your browser encrypts everything before it uploads. The secret key stays on your device.
Step 3: Share the link
Send the link to your recipient. Only people with the link can unlock and view your files.
