If you have ever tried to send a large file to a friend, a client, or a coworker, you have probably reached for WeTransfer. It works, but it comes with trade-offs: a 2 GB cap on the free plan, your files sitting on someone else's servers, ads, and the constant nudge to create an account. If you are looking for a free WeTransfer alternative that drops those limits, ZetaShare was built for exactly this.
ZetaShare is a peer-to-peer (P2P) file sharing tool that sends files straight from your browser to the recipient's browser. There is no upload to a central server in the middle, no account to create, and no size limit imposed on you. Transfers are encrypted with DTLS 1.3 the whole way.
Why look for a WeTransfer alternative?
WeTransfer is convenient, but a few things push people to look elsewhere:
- Size limits. The free tier caps you at 2 GB per transfer. Larger projects mean paying or splitting files.
- Your files live on a server. Uploaded files are stored on WeTransfer's infrastructure until they expire, which some people would rather avoid for private documents.
- Sign-up pressure and ads. The free experience pushes accounts and shows promotional content.
- Expiry windows. Free links expire quickly, so the recipient has to grab the file fast.
How ZetaShare is different
No size limits
Because ZetaShare streams your file directly to the other person instead of uploading it to a server first, there is no artificial cap. The practical limit is your connection and the time you are both online — not a plan tier.
No server in the middle
ZetaShare uses WebRTC to open a direct browser-to-browser connection. Your file is not stored on our servers because it never passes through them. You can read more about how this works in how to send large files without uploading to a server.
No signup
Open the site, pick your file, and share the link. There is no account, no email, and no app to install.
Encrypted transfers
Every transfer is protected with DTLS 1.3 encryption while the file is in transit, so the data moving between the two browsers is encrypted end to end.
WeTransfer vs ZetaShare at a glance
- Size limit: WeTransfer 2 GB free / ZetaShare no fixed limit.
- Storage: WeTransfer stores files on its servers / ZetaShare keeps files off any server.
- Account: WeTransfer nudges signup / ZetaShare needs none.
- Encryption: Both encrypt in transit; ZetaShare keeps the file strictly between the two browsers.
How to send a large file with ZetaShare
- Open ZetaShare in your browser.
- Select the file (or files) you want to send.
- Optionally lock it with a password for the recipient.
- Share the generated link with the other person.
- Keep the tab open while they download — the transfer is direct, so both of you stay connected until it finishes.
That is it. No upload bar that has to finish before you can share, and no waiting for a server to process the file.
