Add a Background to a Screenshot

Look at any product announcement that did well on X or LinkedIn and the screenshot in it is almost never a bare rectangle. It sits on a coloured or gradient field with even space around it, slightly rounded corners and a soft shadow, which makes a flat capture read as an object with depth and makes the post stand out in a feed of plain text and photos. This page adds exactly those four, and gives you a PNG ready to post, paste into a slide or drop into a README.

First, the background adds space but not pixels: a small or zoomed-out capture will still look small, so take the screenshot at the window's real size and crop in on the part that matters before framing it. Second, screenshots carry things you may not want public, other tabs, notification previews, names in a sidebar, and a backdrop draws more eyes to the image. Hide those with the Blur and Redact tool on this site first. The composition is done on your device, so an internal dashboard or an unreleased feature is never uploaded to be decorated. Choose a background that contrasts with the screenshot's own edge colour; a white app window on a white field loses its outline, which is where a darker gradient or the shadow earns its place.
