"Transfer files with E2E encryption"
Editorial Review & Verification
Hands-on VerifiedSecure high-speed transfer of large files up to 10GB with client-side end-to-end encryption and self-destructing links.
+ Key Strengths (Pros)
- ✓ In-browser WebCrypto end-to-end encryption ensures neither relay servers nor storage hosts can inspect file contents
- ✓ Decryption key is confined to the client-side URL hash anchor, isolating it from server access logs
- ✓ Generous file ceiling up to 10GB with streaming chunk uploads to Backblaze B2 and real-time WebSocket signaling
- ✓ Configurable auto-expiration based on time (up to 24 hours) or download count (up to 100 downloads)
− Limitations (Cons)
- − Files stored on temporary cloud relay expire automatically after 24 hours without option for permanent archiving
- − Large multi-gigabyte transfers over slower connections require keeping the browser tab open until upload completes
Deep Privacy & Sandbox Audit & Product Power & Utility Review
Zero-knowledge end-to-end encryption verified. File bytes are encrypted in browser memory before transmission to Backblaze B2 storage; the decryption key exists exclusively in the client-side URL hash.
Uploaded sample.png test fixture into dropzone. In-browser WebCrypto encryption dispatched ciphertext to Backblaze B2 endpoint pod-000-1084-18.backblaze.com via WebSocket coordination, returning 50-character hash URL to clipboard.

IcyZip pairs exactly two open browsers by QR code or short private link. Current v4 clients exchange P-256 ECDH public keys after pairing and derive separate text and file keys with HKDF-SHA-256; no encryption key is embedded in the QR code or link. The relay sees ciphertext plus necessary connection data and file name, type and size. No account or app is required; both browsers stay open and online. The hosted service is proprietary; its isolated E2EE component and tests are Apache-2.0.
