Share a clipboard between two computers
A work PC and a personal laptop, a desktop and a notebook, two different operating systems — open a room in the browser on both, pair with a 6-digit code, and copy on one to paste on the other.
Running two computers at once is common — a desktop and a laptop, a work machine and a personal one — and they almost never share a clipboard. Windows keeps its clipboard history to itself, macOS shares only with other Apple devices, and a mixed pair (a Mac and a Windows PC, say) has nothing in common at all. So a URL or a snippet of text you need on the other machine usually goes through chat or email.
A shared room fixes that for any two computers. Open the same site in the browser on both, pair once with a six-digit code, and the room becomes a clipboard they both reach — copy on one, paste on the other, including links and files, not just text.
How to do it in three steps
- 1
Open a room
Go to pastehere.app in any browser and create a room. You'll get a six-digit code — no sign-up, nothing to install.
- 2
Pair the second device
Open the same site on the other device and type the six-digit code (or scan the QR) to join. The devices agree on a key directly, so the server never sees it.
- 3
Copy on one, paste on the other
Add text, a link, an image or a file on either device and it appears on the other within a second. Destroy the room when you're done.
Everything is encrypted in your browser with AES-256 before it leaves the device. Devices agree on the room key through a PAKE exchange over the 6-digit code, so the key never reaches the server — it only ever stores ciphertext.
Across operating systems, with nothing installed
Because it lives in the browser, the room doesn't care whether the two computers run Windows, macOS or Linux, and it needs no software on either. That makes it especially useful when one machine is locked down — a corporate laptop where you can't install a sync client — since the browser is all it needs.
Safe for code and credentials
Everything is encrypted in your browser with AES-256 before it leaves, and the key is agreed directly between the two computers, so the server only stores ciphertext. That makes it sound for the things developers and admins move between machines — config snippets, tokens, commands — and you can destroy the room when you're finished.
Questions
How do I share a clipboard between a Windows PC and a Mac?
They share no native clipboard, so open a pastehere room in the browser on both and pair with the 6-digit code. Then copy on one and paste on the other — text, links or files.
Can I sync the clipboard between two computers without installing anything?
Yes. pastehere runs entirely in the browser, so there's nothing to install on either computer and no account. Pairing is just a 6-digit code.
Is it safe to copy passwords or code between machines this way?
Yes. Content is end-to-end encrypted with AES-256 and the server never sees the key, only ciphertext. Destroy the room when you're done to remove it everywhere.
