This is the core of Perkoon. When both you and your recipient are online, files are beamed directly from your browser to theirs. The data never passes through Perkoon's servers, which means there are absolutely no file size limits, no mandatory accounts, and complete privacy.

Frequently Asked Questions

Perkoon FAQ

Is the P2P transfer really free forever?

Yes, absolutely. Perkoon's peer-to-peer transfer is free forever because of how it works. The files are sent directly from your device to the recipient's device without ever being stored on or passing through Perkoon's servers. This means it costs Perkoon virtually nothing in bandwidth or storage, so they can offer it completely free, with no hidden limits or future fees.

What happens if the other person is offline?

If the recipient is not online to receive the direct P2P transfer, Perkoon offers a solution: encrypted cloud storage. This is a paid feature. You can upload the file to Perkoon's secure servers, and they will hold it for your recipient. When the recipient comes online, they can download it from this temporary cloud storage. You only pay for this cloud storage feature.

Can Perkoon see what I'm sending with P2P?

No, they cannot. During a P2P transfer, your file is broken into encrypted chunks and streamed directly between your browser and the recipient's browser using a secure WebRTC connection. Perkoon's servers only help set up this direct connection (a process called signaling) but never handle the actual file data. They literally have no way to see your files.

Can I use Perkoon with any web browser?

For the best, unlimited experience, Perkoon recommends using Chromium-based browsers like Chrome, Edge, or Brave. These browsers fully support the required technologies. Firefox and Safari can be used, but they have inherent browser restrictions that may limit performance or file size for P2P transfers. It's always best to check the official site for the most current browser compatibility information.
