Supa TransferA WeTransfer alternative for large files
WeTransfer's free plan stops at 3 GB or 10 transfers in any 30 days, whichever comes first, and keeps each transfer on its servers for 3 days. If your files are bigger than that, or you'd rather no copy sat on a server, here is how the alternatives compare, Supa Transfer included.
Free plans compared
| Free size limit | Copy kept on a server | Recipient needs | End-to-end encrypted | |

When an upload service is the better choice
WeTransfer, Smash, SwissTransfer and Dropbox Transfer upload your files first and send a link. That suits you when:
- The recipient shouldn't install anything. They open the link in a browser, with no account.
- You want to switch off. Once the upload finishes, your computer can go to sleep; the link works for days.
- The files are small, within the free limit.
When Supa Transfer is the better choice
Supa Transfer sends files straight from your computer to theirs, so:
- Bigger files on the free plan: up to 50 GB a month each way, or unlimited on Pro for $2.99 a month.
- No copy on anyone's server: nothing is uploaded first or left behind, and connections are encrypted end to end with QUIC and TLS 1.3.
- No waiting for an upload: the download starts as soon as they paste the ticket.
- It survives bad connections: a dropped connection retries and picks up where it stopped, and every byte is checked on arrival.
- Only the people you choose: limit a ticket to the emails you list, so a forwarded ticket isn't enough.
The trade-offs: the other person needs the app and a free account too, and your computer has to stay on and sharing until they're done. If they're downloading over days, an upload service fits better.
Switching from WeTransfer
- Download Supa Transfer for Mac, Windows or Linux, and sign in.
- Drop the files or folder in and click Copy ticket.
- Send the ticket in any chat or email, as you'd send a WeTransfer link, with a note to get the app.
- Keep Supa Transfer sharing until they've downloaded. Closing the window keeps it going from the menu bar or tray.
