Core Features
CopyPaster is built to handle quick data transfers between browsers without the overhead of heavy cloud drives or messengers.
No signup, no emails, and no passwords required. Just open CopyPaster, type or paste your text, and it's shared immediately.
Devices connected to the same local network, office router, or Wi-Fi hotspot automatically connect to the same temporary room.
Share plain text, links, documents, PDF reports, web URLs, and image files up to 10MB instantly across your active devices.
Any files you upload are configured to automatically expire and get completely purged from R2 storage after exactly one hour.
Fully responsive layouts designed to match any platform—Windows PC, Apple Mac, iPhone, iPad, Android phone, or Linux system.
Need to send passwords or API keys? Create secure end-to-end encrypted notes that self-destruct immediately after they are read.
How it works
CopyPaster creates a temporary room from the public IP address visible to the service. Devices routed through that same address can see the room content without creating an account. This is useful for quick transfers, but it is not end-to-end encrypted or intended for confidential data.
Step 1
Connect both devices through the same public internet connection, then open CopyPaster in each browser.
Step 2
Use Text for notes and links, Files for temporary uploads, or Chat for short room conversations.
Step 3
Matching room keys mean both browsers were assigned to the same public-IP room.
The text panel accepts up to 20,000 characters and synchronizes changes between room participants. Chat is designed for short messages. File sharing accepts PNG, JPG, WEBP, PDF, TXT, and DOCX files up to 10 MB. Uploaded files expire after one hour.
A public-IP room is shared by anyone whose traffic reaches CopyPaster through the same public address. That can include family members, coworkers, school users, customers on guest Wi-Fi, or devices behind a VPN gateway. Do not paste passwords, payment details, private keys, medical records, or other sensitive information.
Clear shared text and chat when the handoff is complete. Remove files sooner if they are no longer needed instead of waiting for automatic expiry. If two devices show different room keys, they are using different public routes and will not share the same room.
Read practical instructions before sharing important material, especially on workplace, school, guest Wi-Fi, carrier, or VPN connections.

CopyPaster is a fast, web-based tool that lets you transfer text, notes, and files between devices connected to the same public IP address without requiring any registration or account creation.
Open CopyPaster in each browser on your devices. Ensure they are connected to the same network (Wi-Fi, office network, or mobile hotspot sharing) which routes them through the same public IP. The room keys displayed at the top of the workspace will match, indicating the devices are connected to the same clipboard room.
CopyPaster is designed for quick, non-sensitive data transfers. Because a room is determined by the public IP, anyone sharing that same public IP (such as others on the same guest Wi-Fi, school network, or VPN gateway) could potentially access the room. Avoid pasting passwords, payment cards, or sensitive personal documents.
All files uploaded to a public room are automatically deleted from storage after exactly one hour. Shared text, chat messages, and files can also be deleted manually at any time to clear them immediately from the room.
