What is it?

WinShot is a desktop screenshot app for Windows that captures the full screen, a selected region, or the active window, then opens the result in an editor. The editor offers shapes, arrows, lines, text, numbered markers and spotlight annotations, along with non-destructive cropping with aspect ratio presets.

Exports can be saved as PNG or JPEG with an adjustable quality setting, and screenshots can be wrapped in one of 24 gradient backgrounds with padding, rounded corners and shadows. Global hotkeys, a system tray icon, and quick save to a configured folder make it fast to use for repeated captures.

The app is built with Wails, using a Go backend for screen capture and system integration and a React + TypeScript frontend with react-konva for canvas editing. It ships as a portable executable or an NSIS installer and requires Windows 10 or later with the WebView2 runtime.
