What is a window screenshot?

A window screenshot is an image of application content framed inside a simulated operating-system window — complete with a title bar, traffic-light or close/minimize/maximize buttons, and rounded corners. Developers and designers use these mock-ups in blog posts, documentation, landing pages, and social media to present their work in a polished, recognizable context without needing to take an actual screenshot on a specific machine.

Tool description

This tool wraps any uploaded image inside a realistic macOS or Windows window frame and lets you export the result as a PNG. Upload a screenshot or any other image, pick an OS style, set the window title, adjust the width and height, and choose how the image fits inside the frame. You can also customize the title bar and background colors and toggle rounded corners to match your design.

Features

  • macOS and Windows styles — generate a window frame that matches either operating system's visual language.
  • Flexible image fitting — choose "contain" to letterbox the image or "cover" to fill the frame edge-to-edge.
  • Full style control — set a custom title, title bar color, background color, and toggle rounded corners before exporting.
