The Cost of Sharing Large Files
Most cloud storage platforms restrict free file sharing. Free accounts typically offer limited storage (such as 2GB to 15GB), and sending larger files requires a paid subscription. In addition to subscription fees, cloud platforms often limit upload speeds and download bandwidth for free users, leading to slower transfers.
These limits exist because storing files on remote servers carries infrastructure and bandwidth costs. By shifting to a serverless model where files stream directly between devices, you can transfer files of any size without storage or subscription costs.
How P2P Technology Enables Free, Unlimited Sharing
Direct peer-to-peer (P2P) file sharing avoids the costs associated with server storage. By connecting the sender and receiver directly, the files transfer in real-time. Since no files are uploaded to or stored on web servers, there are no storage infrastructure costs, allowing the platform to offer unlimited transfers for free.
This direct connection is established in your browser using WebRTC. Once connected, your files are read from local storage, encrypted client-side, and streamed directly to the recipient, ensuring a fast and secure transfer.
| Transfer Metric | Standard Cloud Services | Direct P2P Client (WebRTC) |
|---|---|---|
| Service Cost | Requires subscription for files over 2-15GB | 100% Free; no file size limits or subscriptions |
| Account Signup | Required to manage and share files | No account required; immediate transfer |
| Transfer Speed | Throttled for free accounts | Limited only by your direct internet speed |
| File Retention | Files stored permanently or until deleted | Zero retention; files are not stored on servers |
Efficient Streaming for Large Files
Transferring large files, such as 20GB or 100GB, directly through a browser requires careful resource management to avoid crashes. Standard browsers cannot load very large files directly into memory. Our platform uses standard browser APIs to read files from local storage in small blocks.
Each block is encrypted client-side using AES-256-GCM and sent across the direct WebRTC connection. The receiving browser decrypts the blocks in real-time and saves them using the File System Access API. This chunk-by-chunk approach maintains low memory usage, ensuring a stable transfer for files of any size.
Security: E2EE Client-Side Encryption
While the service is free, it does not compromise on security. Files are encrypted client-side using AES-256-GCM. The decryption key is generated in your browser and appended to the sharing link as a hash parameter. Because the hash is never sent to the signaling server, the keys remain local to your device, ensuring privacy.
Frequently Asked Questions on Free Transfers
How is this service free with no limits?
By using peer-to-peer technology, files stream directly between devices instead of storing them on our servers, avoiding server storage costs.
Do I need to sign up for an account?
No. You can open the page, select your files, and start transferring immediately without registering.
Are my file transfers private?
Yes. All transfers are encrypted client-side, and the decryption keys are stored only in the sharing link hash on your device.
What is the maximum file size?
There is no size limit. The platform can transfer files of any size by streaming them directly between browsers.
