End-to-end encrypted file transfer for humans and the agents working alongside them. Files are sealed with AES-256 in your browser. We never hold the key.
No accounts, no installs. Drop a file, share a link, watch it expire on schedule.
Drag and drop or browse. Any file type, up to 2 GB on the free plan, 100 GB on Pro.
AES-256-GCM runs locally before a single byte leaves your machine. The key stays with you.
Copy or email it. The decryption key lives in the URL fragment — never sent to our servers.
Privacy-first defaults. No tracking pixels, no data mining, no surprises.
AES-256-GCM in your browser. We never see your files, your keys, or your recipients.
Chunked uploads with parallel processing. Gigabytes saturate your line, not your patience.
Pick the lifespan. Past that, ciphertext is shredded server-side.
Optional second factor. Even with the link, no password means no payload.
Send straight to a recipient with a note. Delivery receipts on Pro.
SendFast is the file transfer layer for agentic workflows. Your assistants ship encrypted reports, exports, and generated artifacts straight to their humans — without ever touching a service that can read them.
// Your AI agent sends files via SendFast const transfer = await sendfast.upload({ files: [encryptedReport], expiry: "7d", email: "[email protected]", message: "Your weekly analytics report", passwordProtect: true, }); // → Encrypted, delivered, zero-knowledge. console.log(transfer.shareUrl); // https://sendfast.raicode.tech/t/abc#K2x...vQ9
No hidden seats, no per-gigabyte surprises. Same encryption on every tier.
No account needed. Drag, drop, and share — your files are encrypted before they ever leave your browser.
