Secure file transfer with end-to-end encryption.
Send sensitive files through encrypted links instead of risky email attachments or generic cloud shares.
What secure file transfer means
Secure file transfer should protect the file before it leaves your device, limit who can access it, and remove access when it is no longer needed. SecureTransfer encrypts files in your browser, then uploads only encrypted data.
Why email attachments and generic cloud links are weak
Email attachments
Attachments can be forwarded, retained in mailboxes, and copied across servers.
Generic cloud links
Cloud drives often prioritize collaboration and long-term storage over short-lived delivery.
SecureTransfer links
Use browser-side encryption, expiry, download limits, and tracking for file delivery.
Browser-side encryption
Your browser generates an encryption key and encrypts the file locally. The key is placed after the # in the share URL. Browsers do not send URL fragments to servers, so SecureTransfer stores encrypted blobs without receiving the key.
Expiring links and download limits
Set a short expiry for sensitive files or cap downloads so access ends after the intended recipient retrieves the file.
Frequently asked questions
- Is SecureTransfer end-to-end encrypted?
- Yes. Files are encrypted in your browser before upload and decrypted in the recipient’s browser.
- Can SecureTransfer read my files?
- No. The decryption key is stored in the URL fragment, which is not sent to the server.
- Do recipients need an account?
- No. Recipients can open the secure link and download without creating an account.
- How long do files stay available?
- You choose an expiry from short-lived links to longer storage options; files are deleted after expiry.
- Can I set download limits?
- Yes. You can set a maximum number of downloads for a transfer.
