How to Copy, Paste & Drag Files Between Any Devices

When it comes to transferring files or text between a Windows PC and a Mac, or an iPhone and an Android device, the experience is often frustrating. You usually have to rely on messaging apps like WhatsApp or email, which means navigating menus, clicking "upload," and waiting.

We believe that sharing data across your own devices should feel like you're working on a single, unified machine. That's why we engineered Textunnel to support Global Drag & Drop and Global Clipboard Listeners.

Here is how you can achieve a true desktop-class file sharing experience directly in your browser.

The Problem with "Upload Buttons"

Most file-sharing websites force you to click a tiny paperclip icon, open your system's file explorer, find the file, select it, and hit open. If you just took a screenshot using Ctrl+Shift+S (Windows) or Cmd+Shift+4 (Mac), that screenshot is sitting in your clipboard, not saved as a file yet.

To send it, you'd have to save it to your desktop first, and then upload it. That's way too much friction.

Enter Global Clipboard Listeners

In the latest update to Textunnel, we completely eliminated the need for the upload button (though it's still there if you prefer it).

Now, you can drop files onto your devices using the two most intuitive gestures on modern operating systems: Drag & Drop and Clipboard Paste.

1. Drag & Drop (Files, Folders & Large Videos)

Got a 2GB video file on your desktop? Don't open a file picker. Just drag it from your file manager (Finder on macOS, File Explorer on Windows, or Nautilus on Linux) and drop it straight onto the target device avatar inside Textunnel.

• Drop Zones Everywhere: You can drop directly onto a device card to send instantly, or drop anywhere in the general room area to queue files.
• Folder Support: Dragging an entire folder automatically packages and streams the file hierarchy over WebRTC without requiring manual zipping.
• Visual Feedback: The interface glows with clear visual indicators the moment a dragged item enters the window.

2. Copy & Paste (Ctrl+V / Cmd+V)

Ever took a quick screenshot (Win + Shift + S or Cmd + Shift + 4), had it copied to your clipboard, and just wanted it on your phone immediately without saving it to disk first?

1. Copy anything on your computer (an image, text snippet, or actual file).
2. Switch to the Textunnel browser tab.
3. Press Ctrl + V (Windows/Linux) or Cmd + V (macOS).

Textunnel immediately intercepts the clipboard data, detects whether it is an image buffer, raw text, or file stream, and prompts you with a 1-click send dialog.

Zero Friction, Maximum Speed

No menus. No navigating subfolders. Just drag, paste, and drop.

Open Textunnel, pair your devices, and experience what cross-platform sharing should actually feel like.
