About Clipcroft

Clipcroft is a real-time clipboard for moving text and files between devices. It works in any modern browser, requires no account, and never stores your content on a server.

Why this exists

Sending a file from one device to another should be instant — but the existing options all have a catch. AirDrop only works between Apple devices. Universal Clipboard requires the same iCloud account and no Windows or Android in the loop. Cloud uploads put your files on someone else's infrastructure, sometimes for days. USB cables require finding the right cable and unlocking both devices.

Clipcroft fills the gap. Open the same short clipboard name on any two devices in any browser, and your text and files appear on both sides in real time. The transfer happens directly between the browsers; nothing passes through our servers.

How it works in one paragraph

Each Clipcroft clipboard is identified by a short name you pick — like "624" or "myphone". When two devices open the same name, the browsers establish a direct peer-to-peer connection using WebRTC, the same browser-to-browser technology that powers Google Meet and most modern video calls. Files travel from your browser to the recipient's browser without ever touching our infrastructure. Text is relayed through a small signaling server and discarded immediately on delivery — except when it exceeds 256 KB, in which case it routes through WebRTC like a file. If you set an optional password when creating the clipboard, the contents are end-to-end encrypted in your browser before they leave the device.

What we don't do

• We don't store your files. Files travel browser-to-browser via WebRTC and are never written to any server.
• We don't ask for an account. No registration, no email, no account password. Your clipboard ID is a session key, not a profile.
• We don't track you across the web. Clipcroft does not load third-party tracking scripts; the only third-party calls are an optional anonymous error-reporting library (Application Insights) and an ad network for users who exceed the free tier and choose to see an ad.
• We don't lock you to a platform. Clipcroft works on Windows, macOS, Linux, Chrome OS, iOS, and Android in any modern browser.

What you can do

• Move text and files between an iPhone and a Windows PC, a Mac and an Android phone, or any other combination of devices and operating systems.
• Drag-and-drop whole folders, paste screenshots, share links across devices in real time.
• Connect up to 20 devices to the same clipboard simultaneously, with deletions synced live.
• Optionally protect a clipboard with a password — encryption keys are derived locally and only ciphertext leaves your device.
• Resume interrupted transfers automatically; partial uploads continue from the last received chunk on reconnect.
