The large file transfer problem
Sending a large file over the internet usually means one of these: uploading it to a cloud service that imposes a size limit, creating an account, waiting for the entire upload to finish before the other person can start downloading, and trusting that the service won't read your file.
Achuray changes this equation entirely. It's a peer-to-peer file transfer service via WebRTC that connects your browser directly to the receiver's. The file never passes through an Achuray server. It travels over its own encrypted connection from browser to browser.
Achuray comes from Quechua, an indigenous language of the Andes. It means "to distribute" or "to deal out" — exactly what the tool does: deliver a file directly from one person to another.
How Achuray works in three steps
1. Pick your file — The file stays on your device. Achuray creates a private, temporary transfer room, not an upload. There's no intermediate storage.
2. Share one link — Send the private link or let the receiver scan the QR code. You stay online while the other person connects.
3. Go direct — The browsers form an encrypted WebRTC connection and stream the file straight to the receiver. Achuray's server only relays the small messages both browsers need to find each other.
Why direct transfer wins
No cloud detour — You don't wait for an upload to finish before the other person can start downloading. The receiver gets the file in real time as it streams.
Private by design — WebRTC uses encrypted transport. Achuray never reads or stores the free transfer. File bytes travel directly from sender to receiver.
No product-level size limit — Achuray doesn't impose a preset size limit. Practical limits depend on browser support, free disk space, connection stability, and network policies. Chrome and Edge can stream very large files directly to disk.
Presence, explained — Both people always see who's online, what's happening, and why the sender's tab must stay open. No surprises or silently interrupted transfers.
Send the heavy stuff. No upload, no account, no limit.

Frequently asked questions
Does Achuray upload my file? No, for free direct transfers. The server only relays the small messages both browsers need to find each other. File bytes move over the WebRTC data channel.
Why must the sender stay online? The sender's browser is the source of the file. Closing the tab, sleeping the device, or losing connectivity removes that source. Achuray shows presence clearly throughout the transfer.
Is there really no size limit? Achuray doesn't impose a preset limit. Practical limits depend on browser support, free disk space, connection stability, and network policies.
What if a direct connection is blocked? A configured TURN relay can carry the encrypted WebRTC traffic across restrictive networks. Achuray still can't inspect the file, though relay bandwidth has an infrastructure cost.
Is it free? Yes, direct transfers are free forever. Achuray Pro will be an optional layer for storage and advanced features.
Do I need to create an account? No. To send and receive files directly you don't need any account or registration.
