Any File Type
Whether you are sharing high-resolution photos, music folders, or documents, we preserve original files.
High Speed Upload
Direct browser streaming utilizes your full ISP bandwidth. No server upload throttle limit.
No Signup Required
Protect your anonymity. Drop your files, get your connection link, and start transferring instantly.
End-to-End Protected Sharing with WeTransfer Secure
Initiate fully protected data transmissions online using WeTransfer Secure. Our serverless architecture avoids storing your files on cloud disks where data could be leaked, intercepted, or indexed. This security-first portal links directly to our primary WeTransfer hub.
By utilizing WebRTC technology, your browser establishes direct encrypted socket tunnels with the recipient. This prevents any intermediate servers from accessing your private documents, databases, or project media.
Security Controls
- ✓ Zero Cloud Storage: Files are streamed directly and never cached on cloud storage server disks.
- ✓ DTLS/SRTP Encryption: Standard browser encryption ensures complete privacy of the data channel.
- ✓ No Credentials Staged: Senders share files without inputting passwords, emails, or personal details.
Full Privacy & Encryption
- ✓ End-to-End Encryption: DTLS/SRTP protocols with AES-256 secure the connection channel completely.
- ✓ No Server Interception: Files are streamed directly and never stored on intermediate cloud server disks.
- ✓ Privacy Protection: No registration, email logins, or account requirements for downloaders.
Step-by-Step Flow: Verifying Direct Encrypted Transfer
Our browser coordinate system initiates direct socket tunnels in seconds. Review the process below.
Stage Local Files
Select folder structures or zip archives. The application loads local file metadata into the session instantly.
Send Secure Link
Copy the direct session link. Share this connection link with the downloader using any messaging platform.
Keep Active Stream
Ensure your browser tab remains open. Once the recipient starts downloading, the data streams live from memory.
NAT Traversal Protocol and Secure Traversal Fallbacks
Most devices on the internet sit behind NAT routers or enterprise firewalls that prevent incoming connections. Our signaling server acts as a coordinator, employing public STUN (Session Traversal Utilities for NAT) servers to discover raw network paths between the sender and recipient.
In cases where extremely strict network policies block direct UDP peer connectivity, the system falls back to a TURN (Traversal Using Relays around NAT) server path. Since all data is fully encrypted end-to-end with local AES-256 keys, the TURN relay server only acts as a blind carrier and cannot inspect the contents of your transfer.
Frequently Asked Questions About WeTransfer Secure
What encryption protocol is active?
The channel relies on standard WebRTC DTLS/SRTP with local AES-256 keys created inside browser memory.
Can your system administrators read my files?
No. Because files are streamed directly browser-to-browser and never staged on our signaling server disks, interception is impossible.
Do you keep database logs of shared files?
No. We do not store filenames, file directories, file sizes, or metadata records on database servers.
Is the connection link secure from crawlers?
Yes. The room URL relies on secure cryptographically random hashes that search engine bots cannot discover or crawl.
What happens to the tunnel if my browser crashes?
If the tab closes unexpectedly, the encryption keys are wiped from memory and the tunnel closes instantly.
Do downloaders need decryption software?
No. Decryption tasks are handled natively by the downloader's web browser, saving files in their raw, original state.
