P2P File Transfer in Browser
Share files directly browser-to-browser with temporary secure room codes, encrypted transmission, and zero permanent cloud storage.
Zero registration required • 100% free • End-to-end encrypted browser stream
No File Size Limits
Send 500 MB PDFs, 10 GB 4K video exports, or 50 GB archives without paying subscriptions or hitting arbitrary cloud caps. If your device can read it, QuickSync can stream it.
Zero Cloud Retention
Your confidential documents and personal media never touch any cloud storage bucket. Once the transfer completes and you close your tab, no digital footprint remains on our servers.
Hardware-Level E2EE
WebRTC DataChannels enforce DTLS and SRTP cryptographic handshakes by standard specification. Intermediate signaling servers and ISPs see only encrypted noise in transit.
QuickSync vs Traditional Cloud File Sharing
Compare how peer-to-peer data pipes outperform centralized cloud uploaders in speed, security, and storage caps.

How WebRTC Eliminates Cloud Latency
When uploading a 10 GB file to conventional services, you spend 20 minutes uploading to their datacenter. Then your recipient spends another 20 minutes downloading. That is a 40-minute round trip with double the bandwidth consumption.
QuickSync establishes a direct peer-to-peer WebRTC connection using STUN/TURN signaling. As soon as you add a file, chunks stream immediately to your recipient's browser. If both devices share the same local office WiFi, data flows over the local network at full gigabit speed without hitting public ISP bottlenecks.
Zero Interception: True Privacy Architecture
Most transfer utilities retain files on cloud storage buckets for 7 to 30 days. During that window, unencrypted or semi-encrypted files are susceptible to subpoena requests, accidental bucket misconfigurations, or employee inspection.
With QuickSync, our server acts solely as a lightweight signaling coordinator to exchange WebRTC session descriptors (SDP) and ICE candidates. Once the connection is negotiated, the media channel is completely detached from our infrastructure. We cannot inspect, decode, or store your documents even if we wanted to.
Frequently Asked Questions
Is there really no file size limit on QuickSync?
Yes. Because QuickSync streams data peer-to-peer via WebRTC DataChannels, your files never occupy storage on our servers. There is no arbitrary 2 GB or 5 GB cap. Whether transferring a 10 MB PDF report or a 40 GB system image, QuickSync transfers it at the full speed of your network connection.
How does QuickSync compare to WeTransfer or Google Drive?
WeTransfer and Google Drive require complete uploads to their cloud infrastructure before generating download links, introducing double latency and leaving data on external servers for days. QuickSync creates a direct encrypted WebRTC tunnel where the recipient downloads chunks in real time as they are sent.
Are my files encrypted during transfer?
Yes. WebRTC mandates strict end-to-end encryption by specification using DTLS (Datagram Transport Layer Security) and SRTP. Even the signaling server that negotiates the connection cannot intercept or decrypt the data passing through the DataChannel.
Why do both sender and recipient need to keep the browser tab open?
In a true peer-to-peer network with zero cloud storage, the sender browser acts as the direct host. Data is streamed in real time from the sender device to the receiver. Closing the browser tab terminates the live data connection.
Does QuickSync work across different operating systems and smartphones?
Yes. QuickSync runs in any modern web browser—including Chrome, Safari, Firefox, and Edge—across Windows, macOS, Linux, iPhone, iPad, and Android without requiring app installations or browser extensions.
Need to Process Files Before Transferring?
Compress huge PDFs, merge reports into single documents, or convert audio files before starting your QuickSync P2P transfer.
