About Clipcroft

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

Why this exists

Sharing a file between devices should be simple — but the existing options all have a catch. AirDrop only works between nearby Apple devices. Universal Clipboard requires the same Apple Account and leaves out Windows and Android entirely. 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 — your text appears on both sides in real time, and files start transferring right away. The transfer happens browser-to-browser; nothing is stored on our servers.

How it works in one paragraph

Each Clipcroft clipboard is identified by a short name — generated for you, or one you choose — like "coolfox07" or "myphone". When two devices open the same name, the browsers establish a 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; if the two can't connect directly, the encrypted file stream is relayed through one of our servers, which never stores or reads it. Text is relayed through a small signaling server and discarded immediately on delivery — except when it exceeds 64 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 name is a session key, not a profile.
• Your data stays yours. Clipcroft has no accounts and stores none of your content, so it stays on your devices. It loads no analytics, and error reports go to our own server (same origin), redacted before storage. Clipcroft is free because it shows ads served by Adsterra, which may use cookies or similar technologies to serve and measure ads — our privacy policy details what that involves.
• 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

• Share 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 groups of files or whole folders, and share text and 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 everything is encrypted before it leaves your browser.
• Resume interrupted transfers automatically — on reconnect they continue from where they left off, not from the start.
