Core How-Tos
Resize & snap windows
Put your browser window at exactly the size you need — for responsive checks or side-by-side work — in one click.
Resize to a preset
The window resizer sets your browser window to common device sizes instantly:
- Mobile
- Tablet
- Laptop
- Desktop
- Full HD
This is handy for quickly checking how a page looks at different screen sizes.
Snap to a zone
Snap zones let you place the window into part of the screen without dragging:
- Halves — fill the left or right half of the screen.
- Quarters — tuck the window into a corner.
- Thirds — line up windows in columns.
Snapping makes it easy to set up side-by-side work — for example, your reference on one side and your task on the other.
