BigFileDrop is a free, browser-based file transfer service that sends files directly between devices using peer-to-peer (P2P) WebRTC technology. No file size limits, no uploads to servers, no accounts required.

Is there a file size limit?

No. BigFileDrop has no file size limits. You can transfer files of any size directly between browsers — 100MB, 1GB, 10GB or more.

Are my files stored on a server?

No. Files are transferred directly between browsers using WebRTC peer-to-peer technology. Nothing is stored on any server. Your files never leave your devices except to go directly to the recipient.

Is the file transfer encrypted?

Yes. All WebRTC connections use DTLS encryption by default. Your files are encrypted in transit between browsers, making it secure for sensitive documents.

Do I need to create an account?

No. BigFileDrop requires no registration, no email, and no account. Just open the website, select files, and share the generated link with the receiver.

How does BigFileDrop work?

The sender selects files and gets a unique link or QR code. The receiver opens the link and connects directly. Files transfer peer-to-peer via WebRTC, encrypted in transit. A lightweight signaling server only helps establish the initial connection.

How to send large files for free?

Open BigFileDrop.com, drag and drop your files (any size), click Generate Link, and share the link with the receiver. The files transfer directly between your browsers — completely free, no limits.

Can I send files from phone to computer?

Yes. BigFileDrop works on any device with a modern browser — phones, tablets, laptops, and desktops. Just open bigfiledrop.com on both devices and transfer files directly.

Is BigFileDrop better than WeTransfer?

BigFileDrop offers several advantages: no file size limits (WeTransfer limits free users to 2GB), no server uploads (files go directly between devices), no registration required, and all transfers are encrypted. Plus, it is completely free.

Does BigFileDrop work on iPhone and Android?

Yes. BigFileDrop works on any modern mobile browser including Safari on iPhone/iPad and Chrome on Android. No app installation needed.

How to send files too large for email?

Email attachments are typically limited to 25MB. With BigFileDrop, you can send files of any size by sharing a link instead. The recipient opens the link and the file transfers directly — no email size restrictions.

Is BigFileDrop safe to use?

Yes. BigFileDrop uses WebRTC with DTLS encryption for all transfers. Files go directly between browsers without passing through any server. No data is stored, logged, or accessible to anyone except the sender and receiver.
