A free Chrome extension that resizes your browser window to popular desktop and laptop screen sizes with a single click.
Click any preset and your browser window instantly snaps to that resolution. The popup closes automatically so you can get right back to work.
A small overlay appears in the corner of the page showing the current dimensions — whether you click a preset or drag the window edge manually.
Automatically un-maximizes before resizing, so it works reliably every time — even when your browser is in a maximized or snapped state.
No access to your browsing data, history, or tabs. The only content script displays a temporary dimension overlay. No tracking, no analytics.
Under 10 KB total. No background service worker, no network requests. Loads instantly and runs entirely on your machine.
