What Browser Screenshot Mockup does, with a checked example

Browser Screenshot Mockup frames an image you upload inside a drawn browser window: a title bar with window controls, and an address bar that shows text you type. Pick a frame look, drop in the screenshot, and download the finished composite as a single image file. The surprise for most first-time users is that the tool never touches the web. It does not open URLs or capture pages, and the address bar text is purely cosmetic: nothing is fetched, checked, or matched against a real site. Your image is the entire content; the chrome around it is drawn in your browser and nothing is uploaded.

Worked example

A concrete input and expected output from the current implementation.

Input

Upload landing.png, a 1280 by 800 pixel screenshot of a pricing page. Frame style: default browser window. Address bar text: https://example.com/pricing

Expected output

One image file downloaded: the 1280 by 800 screenshot appears unchanged inside a browser window with rounded top corners, a title bar holding three window buttons on the left, and an address bar that reads https://example.com/pricing. The frame adds chrome around the picture, so the exported image is larger than the upload; the page content is neither resized nor cropped.

The tool draws the window chrome around the pixels you supplied and renders the typed address into the bar verbatim, so the output shows exactly your screenshot plus the frame, with the URL text reproduced as typed.

How the result is produced

1

Placing your image

You supply the screenshot as an image file on your device. The tool draws a browser window around it: a top bar with window controls, an address bar, and a window body that holds the picture. The uploaded image is the content, and the chrome is drawn around it, so the picture is not altered. Choose the frame style, then render and download the composite as a single image file.

Address bar and export

The address bar is a plain text field, not a live URL. Whatever you type is drawn into the bar of the final image; the tool loads nothing and checks nothing. When the frame looks right, export one image file of the whole composite and download it. Because the frame adds pixels around the picture, the exported file is larger than the original screenshot.

Good uses

  • Showcase a finished design in a portfolio: present a landing page or app screen inside a browser window so it reads as a real product rather than a flat image.
  • Write user documentation or a README: frame each step-by-step screenshot in the same window style so all captures share one visual language.
  • Build a client deck: give raw screen captures from a demo a uniform, finished look in a pitch or progress report without opening design software.

Limits and checks

  • No capture happens here. If you have not yet taken a screenshot, the tool will not produce one; you must bring the image yourself, and a small, cropped, or low-resolution capture stays exactly that inside the frame.
  • The address bar text is decoration. Typing a real URL neither fetches that page nor verifies it exists, and nothing checks the text against the content, so a URL that contradicts the visible page makes the mockup look like a mistake.
  • The frame grows the image. The export is the screenshot plus the surrounding chrome, so its dimensions differ from the original; if a layout slot has a fixed pixel size, resize the exported file rather than assuming it matches the upload.

Common questions

Does the tool take the screenshot, or do I upload one?

You upload one. The tool has no browser engine and no address to open; it only frames an image you already have. Capture the screen with your operating system's built-in screenshot tool or a browser extension, save the file, and upload it here.

Does the URL in the address bar have to be a real website?

No. It is text drawn into the picture, so a made-up address works fine for a concept or prototype. Keep it plausible: an address that clearly contradicts the page content, such as a login URL over a landing page, will look like an error to careful viewers.
