Send Files Without Uploading to a Server
Eliminate cloud uploads entirely. Stream your files directly to the recipient's browser using in-memory WebRTC DataChannels.
The Problem with Traditional Uploads
When you send a file through conventional platforms, you are required to perform a full upload: your entire file is transmitted to a cloud server, saved to a remote storage disk, and processed by backend software. You must wait for the upload progress bar to hit 100% before the recipient can even begin downloading.
This traditional model introduces two major drawbacks:
- Double Waiting Time: You must first wait for the file to upload to the server, and the recipient must then wait for it to download from the server.
- Third-Party Custody: Your file sits on an external company's storage infrastructure, creating exposure to data leaks, unauthorized access, and automated indexing.
How Streaming Bypasses Server Uploads
ShareOnline fundamentally changes this workflow by streaming the file directly from sender to receiver:
- In-Memory Processing: When you select a file, the browser reads local file chunks into RAM on demand. No file copy is sent to ShareOnline servers.
- Direct Data Channel: Data packets travel directly from your device to the receiving device across an encrypted WebRTC SCTP channel.
- Immediate Reception: The recipient receives and buffers the chunks in real time as you send them, cutting the traditional double-transfer latency in half.
Where Does the Data Go?
The data travels directly across the network path connecting both devices. If both devices are connected to the same local Wi-Fi router, the data stays entirely within your local area network (LAN), never leaving your home or office router. If the devices are on different networks, packets route through the internet directly between public IP endpoints negotiated via STUN.
Why This Protects Sensitive Documents
Because no server receives or saves your file bytes, there is no digital footprint left behind in the cloud. Legal agreements, personal tax documents, confidential presentations, and private photos remain exclusively on the two participating devices.
