Technical Questions

How does peer-to-peer (P2P) file transfer work?

Instead of sending files to a server that then sends them to the recipient, P2P creates a direct connection between the sender and recipient. This offers better speed, privacy, and works even when internet access is limited.

What's the maximum file size Echo can transfer?

Echo has no built-in size limits. You can transfer files of any size, limited only by your device's storage capacity.

How fast are transfers with Echo?

Transfer speeds depend on your network connection. Since Echo creates direct connections between devices, you can achieve your network's maximum speed without server-side throttling.
