Your clipboard, cleaned automatically.

How it works

PasteKlean lives in your system tray and monitors the clipboard. Choose your rules once, then copy normally.

PasteKlean preferences window

One preferences window, no clutter

Enable the cleaning rules you want, set a global shortcut, and choose whether to start at login. No wizard, no account, no unnecessary options.

  • Auto-clean every copy
  • Manual clean with a hotkey or tray click
  • Optional toast notifications
  • Launch at login

Instant feedback

When you click "Clean Now" or press your shortcut, PasteKlean tells you exactly what happened. Clean text is already on your clipboard, ready to paste.

Everything runs locally on your machine. There are no servers, no analytics, and no accounts.
