Send a 40GB file for free, no upload limit.
Most “free” file tools quietly cap you at a few gigabytes or make you wait through a slow cloud upload. Volo sends files of any size straight from one device to the other — no account, no upload, no storage bill to pass on to you.

How Volo handles a file this big
Volo reads your file in small slices and streams them directly to the other device, which writes each slice straight to disk. The whole file never has to fit in memory, so a 40GB video is handled the same way as a 40MB photo — there's just more of it.
Because the data travels device-to-device over an encrypted WebRTC connection, there's no server in the middle imposing a size cap. The practical limit is simply how much free disk space the receiving device has.
Why other free tools stop you at a few GB
Tools that route your file through the cloud have to store it, pay for the bandwidth, and clean it up later — so they cap free transfers (often at 2GB) and expire your link. Volo doesn't store anything, so there's nothing to cap and nothing to pay for.
What you need
- Any modern browser on each device — phone, laptop, or tablet.
- Enough free disk space on the receiving device for the file.
- Both devices open at the same time for the duration of the transfer.
The honest limits
Both devices need to be open at the same time — Volo is a live direct link, not a server that holds your file for later. Keep the tab open until it finishes; it works best on the same Wi-Fi and connects across different networks most of the time.
Frequently asked questions
- Is sending a 40GB file really free?
- Yes. Volo is free with no account and no ads. Because the file moves directly between your devices rather than through cloud storage, there are no storage or bandwidth costs to charge for.
- Is there a maximum file size?
- There's no fixed cap from Volo. The file is streamed straight to disk instead of being held in memory, so the real limit is the receiving device's free disk space. It's built to handle very large videos, on the order of tens of gigabytes (~40GB).
- Does the 40GB file get uploaded anywhere?
- No. The transfer is peer-to-peer over an encrypted connection, so the file goes straight from one device to the other and is never stored on a server or in the cloud.
- What happens if the connection drops partway through?
- The in-progress transfer stops rather than silently corrupting the file. Keep both devices connected for the duration — the connection is most reliable on the same Wi-Fi.
