Secure Browser-to-Browser Sharing with Online File Transfer Secure
When transferring proprietary assets, design plans, client invoices, or private media files, security is non-negotiable. Using standard cloud drives for an online file transfer secure solution is highly vulnerable since files are cached in cleartext on third-party servers.
SendFiles.in establishes a direct browser-to-browser tunnel using military-grade AES-256 encryption. The encryption keys are generated locally inside your browser and never transit through our servers. This ensures that no third party can read your data.
Military-Grade Encryption
- ✓ End-to-End Encryption (E2EE): DTLS/SRTP protocols encrypt packets locally before they transit the network.
- ✓ Local Key Generation: Keys remain isolated within the browser sandbox, preventing third-party access.
- ✓ Zero Intermediary Access: Signaling coordinates the handshakes and withdraws immediately, leaving no server footprint.
Advanced Anonymity
- ✓ No Log Policy: Because no file is uploaded to our databases, there is no storage log of your personal data.
- ✓ No Sign-up Verification: Skip inputting usernames, passwords, or telephone verification codes.
- ✓ Decentralized Resilience: Point-to-point data packets avoid central vulnerability targets entirely.
Browser-Level Encryption
By avoiding database cache points, we simplify security compliance. Your corporate data remains isolated on your device memory. Secure peer-to-peer data channels use DTLS encryption protocols, preventing packet sniffing.
If restrictive security parameters block direct routing paths, STUN and TURN relays step in to establish connection rooms, allowing secure file sharing to occur.
Technical Specifications
Frequently Asked Questions About Online File Transfer Secure
Get answers to common technical questions about file security, size limits, and WebRTC connection safety.
How does a P2P transfer work?
P2P transfers connect the sender and recipient directly. Unlike cloud hosts that require full uploads first, the receiver downloads the file in real time as the sender uploads, saving time and keeping documents secure.
What is the upload size limit for my files?
There are absolutely no size restrictions. Since our platform is a serverless P2P utility, we do not host your files. You can transfer massive files—such as multi-gigabyte video projects or database archives—completely for free.
Do I need an account to send files?
No signup or login is required. You can share files online completely anonymously without entering emails, verifying identities, or logging in. This keeps your transfers private and fast.
How secure is my data during a large file transfer?
Every transfer is encrypted end-to-end using DTLS/SRTP protocols with AES-256. Because your files flow directly through a temporary WebRTC data channel and are never stored on any cloud servers, hackers have no central targets to intercept, providing maximum protection.
Do I need to keep the browser tab open during transfer?
Yes. Since the data is streamed directly from your device memory to the recipient's storage, both the sender and receiver must keep their browser tabs open. If either tab is closed, the connection tunnel closes and the transfer terminates immediately.
Do you compress my files?
No. We transfer your files bit-for-bit in their raw, original state. Your files arrive with zero compression or quality loss.
