Internxt Send

Internxt Send is a zero-knowledge file transfer service from Spanish privacy company Internxt, letting anyone share files up to 5 GB through a simple link while keeping contents encrypted end-to-end before they leave the browser. It gives WeTransfer-style convenience without storing plaintext on any server.

Files are encrypted client-side with AES-256 before upload, split into shards, and distributed across Internxt's object-storage network so that no single node holds a complete, readable copy. Recipients download through a browser with in-browser decryption, and transfers expire automatically to minimise retention.

Key benefits:

• Zero-knowledge encryption means Internxt itself cannot read transferred files
• AES-256 client-side encryption protects contents before they ever leave the browser
• Sharded storage distributes files so no node holds a complete readable copy
• No account required for 5 GB transfers — just upload and share a link
• Auto-expiring links reduce the footprint of sensitive shared material
• GDPR-native data handling under Spanish and EU data protection law

Internxt is headquartered in Valencia, Spain, hosts data in European data centres, and is GDPR compliant with a published independent security audit covering the platform. EU jurisdiction and zero-knowledge architecture place it firmly outside US CLOUD Act reach.

Ideal for journalists, legal professionals, healthcare workers, and privacy-minded teams that want a fast, WeTransfer-like experience with genuine end-to-end confidentiality rather than the legacy TLS-only model.
