Wormhole alternative: WispFile compared
By the WispFile team · Updated 24 September 2026
Wormhole is the closest in spirit: end-to-end encrypted, no account. It stores transfers up to 5 GB (encrypted, for 24 hours) so you can go offline, and goes peer to peer above that. WispFile never stores anything at any size, and adds swarm mode for many receivers and inboxes for receiving; Wormhole is the better pick when you must go offline before a sub-5 GB file is downloaded.
Key facts
- Wormhole: end-to-end encrypted file sharing.
- WispFile: direct, browser to browser, never stored.
- Both are free to start; WispFile needs no account.
- WispFile needs you online while they download.

When Wormhole is the better choice
- The file is under 5 GB and you need to go offline before it is downloaded
When WispFile fits better
- You want nothing stored at all, even encrypted, at any size
- Many people download the same files (swarm mode shares the load)
- You want people to send files to you (inboxes)
How the transfer differs
With Wormhole: up to 5 GB: stored encrypted. Larger: peer to peer. With WispFile, your browser and the recipient’s connect directly, and each 256 KB piece is encrypted with AES-GCM under a 256-bit key that lives only in the link, then checked by the recipient before it is written to disk. A dropped connection resumes where it stopped. Free links are direct only; some office and mobile networks block that, and paid plans add a relay that stores nothing.
Switching from Wormhole
- Open wispfile.com: no account needed.
- Add the files or folder you would have uploaded.
- Share the link the same way you shared the Wormhole link.
- Keep the tab open until the recipient has everything.

Frequently asked questions
Is WispFile a good Wormhole alternative?
For handing files over while you are online, yes: nothing is uploaded or stored, there is no size cap, and files are end-to-end encrypted with a key WispFile never sees. If the recipient will download later while you are offline, Wormhole or another upload-based service is the better fit.
Is WispFile free?
Yes. Direct transfers are free with no size cap and no account. Paid plans add an encrypted relay for networks that block direct connections, plus link names, branding and team features.
Does the recipient need an account or app?
No. They open the link in a browser and download. Nothing to install on either side.
