File Transfer Online Free — Send Files Without Upload

Send Files Without Uploading to the Cloud

Traditional file sharing services — WeTransfer, Google Drive, Dropbox — upload your files to their servers before the recipient can download them. This means your data sits on third-party infrastructure, subject to their terms of service, data retention policies, and potential security breaches.

MiOffice takes a different approach. Files are sent directly from your browser to the recipient's browser using WebRTC peer-to-peer technology. No server stores the file. No cloud account is needed. The connection is encrypted, and when the transfer is complete, there is no copy of your file on any server anywhere.

How to Transfer Files Online (3 Steps)

1. 1

   Open MiOffice Send Files

   Visit the MiOffice Send Files tool in your browser. No download, Guest access on supported tools; AI requires sign-in and credits.

2. 2

   Select Files and Share the Code

   Add the files you want to send, then share the generated join code (or QR code) with the recipient via text, email, or chat.

3. 3

   Recipient Downloads Directly

   The recipient opens the same page, enters the join code, and receives the files directly from your browser. No server in between.

MiOffice vs Cloud File Sharing

When P2P File Transfer Is the Right Choice

• •Sensitive documents — Tax returns, contracts, medical records that should not sit on a cloud server.
• •Large files — Video files, design assets, or data exports that exceed cloud service limits.
• •Same-network transfers — Sending files between your phone and laptop on the same Wi-Fi. P2P is faster than uploading to the cloud and downloading back.
• •No account available — Quick transfers to people who do not have a shared cloud platform or refuse to create an account.

Privacy by Design

MiOffice file transfer uses WebRTC data channels to send files directly between two browsers. The file data is encrypted with DTLS during transit. No MiOffice server ever sees, stores, or caches the file contents. Join codes expire after 30 minutes, and the session is terminated when either party closes the tab. This peer-to-peer architecture means there is no server to breach, no data to subpoena, and no retention policy to worry about.
