About Perkoon

Unlimited Free Peer-to-Peer (P2P) Transfers

Perkoon's flagship feature is its unlimited, free file transfer service using WebRTC-based peer-to-peer technology. When both the sender and recipient are online simultaneously, files are transmitted directly between their web browsers. This method imposes no file size limits, requires no user accounts, and ensures high privacy as the data never traverses Perkoon's servers. The operational cost of this direct streaming is negligible for the company, which allows them to offer it as a permanent free service, fundamentally distinguishing it from competitors that use "freemium" models with strict caps.

Encrypted Cloud Storage for Offline Recipients

To address the common scenario where a recipient is not immediately available, Perkoon offers encrypted cloud storage as a paid feature. Files are securely uploaded to Perkoon's servers, encrypted, and held until the recipient is ready to download them. The company is transparent that this is the only paid component of its service, as it honestly reflects the real costs of maintaining server infrastructure, data storage, and bandwidth, creating a sustainable business model without hidden fees or data monetization.

Native AI and Automation Integration

A defining and forward-thinking feature of Perkoon is its built-in support for AI agents and automation scripts. The service exposes a client-side JavaScript object (window.__perkoon) that provides a structured API, allowing automated tools to interface with the file transfer process programmatically. This eliminates the need for unreliable DOM scraping, making Perkoon a first-class citizen in automated workflows, data pipelines, and AI-assisted operations where manual browser interaction is impractical.

Privacy-First Design and Transparent Operations

Perkoon is architected with a privacy-first philosophy. For P2P transfers, the company has zero access to file content or metadata. For cloud storage, files are encrypted on the client side or on Perkoon's servers. The service explicitly does not scan, analyze, or sell user data. This commitment is coupled with radical transparency about its business model, browser compatibility (noting limitations in Firefox and Safari), and the clear rationale behind what is free versus what is paid, fostering user trust.

Perkoon

Sending Large Media Files to Clients

Freelance videographers, photographers, and designers can use Perkoon's unlimited P2P transfer to send multi-gigabyte project files, raw footage, or high-resolution image sets directly to clients. This bypasses the restrictive file size limits of email attachments or free tiers of other services, and the direct transfer ensures fast speeds and privacy without the files being stored on an intermediate server.

Asynchronous File Sharing for Distributed Teams

Remote teams and collaborators across different time zones can utilize Perkoon's encrypted cloud storage. A team member can upload a file to the cloud, and recipients can download it at their convenience, regardless of the sender's online status. This is ideal for sharing daily build files, documentation, or reports without requiring real-time coordination.

Automated Data Pipeline and Backup Scripts

Developers and system administrators can leverage Perkoon's native API for automation. Scripts can be written to automatically upload log files, database dumps, or backup archives to Perkoon's cloud storage as part of a cron job or CI/CD pipeline. The CLI tool and window.__perkoon API enable these transfers without manual browser interaction, making it a robust component in IT infrastructure.

Privacy-Conscious Personal File Sharing

Individuals who are wary of large tech companies profiling their data can use Perkoon for personal file sharing. Whether sending sensitive documents, personal videos, or a collection of files to family and friends, the P2P option guarantees that the data is only seen by the intended recipient, aligning with a strong personal privacy ethos.

Perkoon FAQ

Is the peer-to-peer transfer really free forever?

Yes, Perkoon's peer-to-peer (P2P) file transfer service is completely free with no file size limits and is intended to remain free indefinitely. The company's rationale is that the direct browser-to-browser streaming technology incurs negligible infrastructure costs for them, as they do not host or relay the file data. This allows them to offer it as a sustainable free service, distinct from their paid cloud storage feature.

What happens if the recipient is not online when I send a file?

If the recipient is offline at the time of transfer, the P2P connection cannot be established. For this scenario, Perkoon offers its encrypted cloud storage service, which is a paid feature. You can upload the file to Perkoon's servers, where it is encrypted and held securely. The recipient then receives a link to download the file at their convenience, once they are online.

How does Perkoon ensure my privacy?

Perkoon ensures privacy through its architecture. For P2P transfers, files are streamed directly between users' browsers using WebRTC, meaning the data never passes through Perkoon's servers and is inaccessible to them. For cloud storage, files are encrypted on their servers. The company has a strict policy of not scanning, analyzing, or selling user data or metadata, making privacy a core operational tenet.

Can I use Perkoon with automation tools or AI agents?

Absolutely. Perkoon is uniquely designed for automation. It provides a client-side JavaScript API (window.__perkoon) that allows AI agents, bots, and custom scripts to interact with the file transfer service programmatically. This means these tools can initiate and manage transfers directly through the API without the need for visually scraping the website, enabling seamless integration into automated workflows.
