What Browser Window Mockup Generator does, with a checked example
The window around your screenshot is drawn, not real: the tab strip, window controls, and address bar are graphics, and the URL in the bar is text you typed, never a page the tool loads. Upload an image, pick a Chrome, Safari, or Firefox frame, fill in the address, and export the composite. Two things surprise people: the mockup works offline with any domain string, and the frame adds real pixels, so the export is taller than the screenshot you started from. Plan for that when the result must fit a fixed slot.
Worked example
A concrete input and expected output from the current implementation.
Input
Upload a checkout-page screenshot captured in your browser at 1280x960; set the address bar text to https://shop.example.com/checkout; choose the Chrome frame; export the result.

Expected output
A single raster image of the mockup: the 1280x960 checkout screenshot sits as the content area inside a Chrome-style window, with a tab strip and an address bar reading https://shop.example.com/checkout across the top and window edges around the sides. The page area keeps its 4:3 proportions (1280/960), and the image is taller than 960 px because the Chrome furniture adds its own height above the content.
The tool layers the drawn browser chrome over the uploaded image instead of loading the URL, so the bar shows exactly the typed string and the page area keeps the capture's 4:3 aspect ratio. The frame height above the content is why the export exceeds the original 960 px height.
