Perkoon
Unlimited Free P2P Transfers
Perkoon's core feature is its unlimited, free peer-to-peer file transfer. When both sender and recipient are online, files are beamed directly from one browser to another. This method imposes no file size limits, requires no accounts, and costs Perkoon nothing in server bandwidth—a saving they pass directly to you. Most importantly, because the data stream never passes through Perkoon's servers, it guarantees unparalleled privacy and speed for your transfers.
Encrypted Cloud Storage for Offline Sending
For when your recipient isn't online, Perkoon offers secure, encrypted cloud storage. This is a paid feature, and Perkoon is upfront about why: honestly covering the cost of running and maintaining the servers that hold your files. Your data is encrypted on their servers, providing a secure "hold" until the other person is ready to download, bridging the gap when instant P2P isn't possible.
Native AI & Automation Integration
Perkoon is built for the future of work. It features a native API (window.__perkoon) that allows AI assistants and automation scripts to interact with the service directly, without the need for inefficient screen-scraping. This means your workflows and AI agents can send and manage files through Perkoon programmatically, seamlessly integrating file transfer into automated processes.
Simple CLI & Browser Tool
Beyond the web interface, Perkoon provides a straightforward Command Line Interface (CLI) tool. This empowers developers, power users, and automated systems to initiate and manage file transfers directly from a terminal, offering flexibility and integration capabilities that go far beyond a standard web upload form.

Perkoon
Sending Large Project Files to Clients
Freelancers and agencies can use Perkoon's free P2P transfer to send massive video edits, design files, or code repositories to clients instantly. There's no need to compress files or split archives across multiple services. Just generate a link, share it, and the client downloads directly from you, with no size caps or wait times.
Secure Document Sharing for Teams
Teams handling sensitive documents, like legal contracts or financial reports, can leverage Perkoon's private P2P streaming. Since files never sit on a third-party server, the risk of a data breach is minimized. For asynchronous sharing, the encrypted cloud storage provides a secure dropbox that only the intended recipient can access.
Automating Backup & File Sync Tasks
Developers and IT professionals can use the Perkoon CLI to script automatic backups of logs, databases, or project assets. By integrating Perkoon into their cron jobs or automation pipelines, they can ensure critical data is transferred to another location without manual intervention, using a reliable and private service.
AI Agent File Management
An AI research assistant can be programmed to use Perkoon's native API to automatically fetch datasets, save processed results, or share generated reports. This turns Perkoon into an intelligent file transfer layer for autonomous agents, enabling them to handle file operations as part of a larger automated task without human oversight.

Perkoon FAQ
Is the P2P transfer really free forever?
Yes, Perkoon's peer-to-peer transfer service is completely free and unlimited, with no plans to charge for it. The company's stance is straightforward: since the data moves directly between users' browsers and costs them virtually nothing in server resources, they have no reason to charge you for it. It's free as a matter of principle, not as a temporary promotion.
What happens if the recipient is offline?
If the recipient is not online to receive the direct P2P transfer, Perkoon can hold the file for them using its encrypted cloud storage feature. This is a paid option because it involves Perkoon using its own servers to store your data temporarily. You can choose this method to ensure your file is delivered as soon as the recipient comes online.
Can Perkoon see what I'm sending via P2P?
No. During a peer-to-peer transfer, your file data is streamed directly between the two browsers (or devices) using a secure WebRTC data channel. Perkoon's servers only help establish the initial connection but do not intercept or have access to the actual file content. They literally cannot see what you are sending.
Which web browsers are supported?
Perkoon works best on Chromium-based browsers like Chrome, Edge, and Brave, which offer full, unrestricted support for the advanced P2P technology. Firefox and Safari can be used but have inherent browser limitations that may affect performance or file size capabilities for direct P2P transfers.
