What viewport widths are simulated?

The tool shows four common breakpoints: 320 px (small mobile), 768 px (tablet / large mobile), 1024 px (laptop), and 1440 px (desktop / wide screen).

Does the preview show the actual pixel dimensions?

Each preview container is constrained to the breakpoint width in CSS pixels. The image inside scales proportionally (object-fit: contain) so you can see how it fills the space without distortion.

Is this the same as browser responsive mode?

It is similar but simplified. Browser DevTools responsive mode resizes the entire viewport. This tool shows four static previews side by side, which is useful for quickly comparing how an image looks across breakpoints.

Upload an image and instantly see how it appears at four common responsive breakpoints: 320 px (mobile), 768 px (tablet), 1024 px (laptop), and 1440 px (desktop). The image is displayed proportionally within each preview container, simulating how a full-width responsive image behaves at each screen width. Useful for designers and developers checking image layouts before publishing.
