Why not use WhatsApp or Google Drive?
| Method | Privacy concern on shared PC |
|---|---|
| Requires WhatsApp login — exposes your phone number and chat history to the lab PC. | |
| Google Drive | Requires Google login — leaves your account signed in on a shared machine. |
| Files pass through third-party mail servers and remain in your Sent folder. | |
| USB Drive | You may not have one, or the lab PC may block USB storage for security. |
| OnlineCopyPaste | ✓ No login. No account. Session destroyed when done. Works right now. |
FAQ
- Do I need to install anything?
- No. OnlineCopyPaste works entirely in the browser. Nothing is installed on the lab PC.
- What file types can I send?
- Images (JPG, PNG, GIF, WebP), PDFs, ZIP archives, text files, code files, Word/Excel documents, and more.
- Is there a file size limit?
- The default maximum is 100 MB per file. Larger files can be zipped before sending.
- Does the file go through your server?
- No. File content is transferred peer-to-peer using WebRTC DataChannels, encrypted with DTLS. The signaling server only helps the two devices find each other — it never sees the file content.
