Anonymously.

Private by design
A private, encrypted alternative to WeTransfer, Dropbox Transfer, and Google Drive share links.
Zero-knowledge by default
Files are encrypted client-side with AES-256-GCM. We store only ciphertext and minimal metadata — never your decryption key.
No account, no email
No sign-up, no verification, no email address. Drop the file, copy the link, walk away.
Auto-delete in 3 days
Uploads expire automatically. Set a shorter window or cap the number of downloads to tighten the blast radius.
Open, auditable crypto
Built on the browser's WebCrypto API. The encryption protocol is documented and independently verifiable.
Resumable uploads
Chunked, parallel multipart uploads via presigned URLs. Bytes stream straight to object storage — never through a backend.
Works everywhere
Any modern browser on any OS. No native app, no extension, no plugin. Your recipient just clicks a link.
How it works
Three steps. No signup, no server that can read your data.
Drop a file
Select or drag any file up to 100 MB. Up to 5 files per drop, directly from your browser.
Encrypt locally
AES-256-GCM encrypts every chunk before upload. The server never sees your plaintext or the decryption key.
Share the link
The decryption key rides in the URL fragment — only whoever you send the link to can open the file.
