Click — zoom.
Click — back. ⚡
One mouse button is the whole interface. Middle click — the screen zooms to 200%. Middle click again — you're back. No key combos, no toolbars, no widgets. And while zoomed, the screen stays fully interactive: click, type and work as usual. Free, for Windows and Linux.

While zoomed, move the cursor to a screen edge — the view glides along.
“I just wanted to look closer and keep working. The built-in magnifiers demand key combos to start, more combos to zoom, and park a toolbar on the screen. Third-party tools were heavy, fiddly or both. I searched for something truly fast and convenient — and found nothing. So I built it.”
Why Magnify.Snap
Instant toggle
One press of the middle mouse button zooms in, another snaps back. Rebind it to any mouse button, key or combination.
Zero friction
The screen stays fully interactive while zoomed — click buttons, type text, drag windows. It's your desktop, just bigger.
Smart panning
The view follows your cursor only when it reaches a screen edge — smooth, predictable, configurable speed.
Native zoom engine
Windows Magnification API, GNOME magnifier or KWin Zoom — hardware-accelerated magnification, no overlays or lag.

Follows the system theme out of the box, with Light and Dark modes one click away. Zoom level from 125% to 800%.
