What is PortalBox?
A macOS screen sharing app that lets you share any region of your screen in Zoom, Google Meet, Teams, and more. Draw a box, get a live preview window, and share only what you want.
PortalBox helps you share exactly what you want, with a live preview window that works in every meeting app.
Share just the right region
Draw a resizable box anywhere on your screen. PortalBox mirrors only that area into a clean preview window, perfect for ultrawide screens.
- Keeps wide-screen shares readable
- Resizable handles for precise framing
- Choose any monitor or area
- Live preview window that stays crisp
Share a clean preview window
PortalBox turns your region into a dedicated preview window you can share in Zoom, Meet, Teams, and more.
- Share once, keep working
- Works with every meeting app
- Move the preview anywhere
- Crisp, focused framing
Pause when you need privacy
Pause or resume the live preview instantly from the menu bar or a shortcut. Nothing updates until you say so.
- One-click pause/resume
- Screen recording only for the preview
- Never records or uploads your screen
More to love:
- Menu bar controls: Quick access to pause, resume, and switch capture modes.
- Multi-display ready: Move the capture region across monitors with ease.
- Resizing handles: Dial in exact dimensions with snap-to handles.
- Window sizing shortcut: Use window selection as a quick sizing shortcut, then share anything inside that region.
- Shortcut support: Pause or resume capture with a global hotkey.
- Privacy by design: Only the selected region is mirrored, nothing more.
