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.
WeTransfer Security Analysis: Secure WebRTC Auditing
Evaluate your risk protocols in our comprehensive WeTransfer Security Analysis. Most traditional setups upload your files to cloud staging servers, leaving them vulnerable to data mining and third-party access. Read more details on our main WeTransfer hub.
By understanding browser-to-browser WebRTC socket streams, you can secure private documents, enterprise backups, and media assets without intermediate disk storage.
Security Audits
- ✓ Zero Disk Footprint: Files stream straight from browser memory, leaving no traces on disk servers.
- ✓ Local Keys: AES-256 keys are created directly in the browser and never shared with signaling hubs.
- ✓ No Tracking logs: We do not log filenames, file contents, IP addresses, or session databases.
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.
Workflow: Securing Point-to-Point Connection Tunnels
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 Security
Are files stored on your servers?
No. Point-to-point transfers move data directly from the sender's browser memory to the receiver's device, skipping server staging entirely.
What encryption protocols do you use?
WebRTC enforces DTLS for connection setup and SRTP for media/data encryption, using local AES-256 keys generated on-device.
Can the signaling server see my files?
No. The signaling server only handles connection metadata to discover local network paths. It has no access to the encrypted data packets.
Is a login required for secure sending?
No. You can send files securely without passwords or registrations, protecting your personal email from data harvesting.
How do you prevent man-in-the-middle attacks?
The point-to-point tunnels utilize certificates generated locally inside the browser. Tunnels are established and verified via DTLS protocols.
What happens to the tunnel when I leave the page?
The encryption keys are instantly flushed from system memory, and the point-to-point socket connection closes permanently.
