UISnap — Precise UI Screenshot Tool

UISnap gives designers and developers a reliable way to capture web UI screenshots for marketing pages, app stores, and presentations — with consistent output every time.

KEY FEATURES

• Exact Dimensions — Set width × height in pixels. Built-in presets for common sizes (1280×800, 1440×900, 1920×1080, 375×812).

• WYSIWYG Window Control — See your current viewport size at a glance. Click "Apply to Window" to instantly resize the browser window to your target dimensions, then verify the layout before capturing.

• Rounded Corners — Apply 0–48 px corner radius, clipped precisely via Canvas API. Works with transparent backgrounds for PNG output.

• Retina / HiDPI Output — Export at 1× or 2× scale. A 1280×800 capture at 2× produces a crisp 2560×1600 image.
