Step-by-Step Guide: How to Send Large Files
Learn how to send large files with WeTransfer protocols. Traditional setups limit free uploads to 2GB or require premium subscriptions for massive folders. Direct peer-to-peer (P2P) transfers bypass all file size caps. Read more on our primary WeTransfer hub.
By learning how to open direct WebRTC tunnels in your browser, you can stream gigabytes of raw videos, databases, or project structures safely with no middleman.
Large Sharing Tools
- ✓ No Upload Delays: Streaming starts immediately when the recipient opens the link.
- ✓ Zero Compression: Files arrive bit-for-bit in their original, raw format.
- ✓ Folder Structures: Maintain complete folder trees during P2P session transfers.
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: Transferring Massive Files Directly
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 Sending Large Files
What is the maximum file size I can send?
There are zero file size limits. You can transfer databases, media files, and archives of any size.
Do I need to sign up to transfer large files?
No. Senders run files straight from memory, avoiding registration or credentials entry.
Is the link secure from public 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.
How do you maintain secure connections?
WebRTC establishes secure channels using DTLS/SRTP with local AES-256 keys generated inside the browser.
Do you log metadata for transfers?
No. File processing is completed locally inside the browser. Senders stream files directly, and zero file metadata is saved.
