SendGB vs tosstome
Last checked
SendGB is a large file transfer site: you upload, it stores the file, and the recipient downloads it from a link or an email. tosstome does not store anything; the file goes from one device to the other while both are online. Which one you want depends on whether the other side is there right now.

When SendGB is the better choice
When the recipient will download the file later, or you are sending one file to several people by email. A peer-to-peer tool cannot hold a file until someone comes to collect it.
When tosstome is the better choice
When the file is going to another of your own devices, or to someone online with you right now. On the same Wi-Fi the file does not go up to the internet and back down, there is no 5 GB ceiling, and no copy sits on a server for a week. For videos of several gigabytes, see sending a large video from your phone.
What tosstome does
- Runs in the browser. Nothing to install on the sending side.
- Devices on the same network see each other automatically. On different networks, one device shows a 6-digit code and the other types it in.
- Files go device to device over WebRTC when the networks allow it. If a direct connection does not come up within a few seconds, they go through a relay on Cloudflare that forwards the bytes and keeps nothing.
- An optional command line tool,
tosstome listen, keeps an always-on inbox on a computer. It prints a link and QR code; open it on a phone and files land in a folder on that computer, with no browser open on the computer side. - Text messages and links travel the same way as files, with a Copy button on the receiving side.
- Nothing is stored. If the receiver is offline, nothing is sent.
What tosstome does not do (yet)
- The relay is protected by TLS between each device and Cloudflare, but it is not end-to-end encrypted yet. Direct WebRTC transfers are encrypted end to end by the browser (DTLS).
- A receiving browser keeps the file in memory until you save it, so very large files are better received with the command line tool, which writes straight to disk.
- Both sides must be online at the same time. There is no "upload now, download tomorrow".
- It is new. Browser-side device pairing and end-to-end encryption on the relay are still being built.
