FilePizza alternative: WispFile compared
By the WispFile team · Updated 24 September 2026
FilePizza pioneered browser-to-browser transfer and is open source, with WebRTC’s transport encryption and an optional password. WispFile uses the same direct model and adds its own end-to-end encryption layer with a key only the link carries, resume after a dropped connection, per-piece integrity checks, inboxes, teams and swarm mode.
Key facts
- FilePizza: open-source peer-to-peer transfer in the browser.
- WispFile: direct, browser to browser, never stored.
- Both are free to start; WispFile needs no account.
- WispFile needs you online while they download.

When FilePizza is the better choice
- You want to self-host the whole thing from its source
When WispFile fits better
- You need a dropped connection to pick up where it stopped
- Files should be encrypted with a key only the link carries, on top of WebRTC’s own
- You want inboxes, teams, or swarm mode for many receivers
How the transfer differs
With FilePizza: peer to peer over WebRTC. 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 FilePizza
- Open wispfile.com: no account needed.
- Add the files or folder you would have uploaded.
- Share the link the same way you shared the FilePizza link.
- Keep the tab open until the recipient has everything.

Frequently asked questions
Is WispFile a good FilePizza 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, FilePizza 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.
