About this tool
A raw screenshot dropped into X, Threads, LinkedIn, a blog post or a slide looks unfinished: hard edges, no breathing room, and whatever colour your desktop happened to be. A quick screenshot mockup, with a background, a frame and a shadow, is usually all it takes to make screenshots look good in a feed. This page is a free screenshot beautifier that runs entirely in your browser. Paste with Ctrl/Cmd+V the moment the page opens, drop a file, or pick one, and the preview appears with a gradient background, 8% padding, 12 px rounded corners, a soft shadow and a macOS window frame already applied. Change any of it and the preview follows. Nothing is uploaded: the picture is drawn onto a canvas in your tab and stays there.
Background, padding, corners, shadow, frame
There are four kinds of background: a solid colour, one of twelve preset gradients, a blurred and enlarged copy of the screenshot itself (the look on most product posts, and it needs no colour choice), or fully transparent. One padding slider sets the space around the screenshot as a share of its shorter side, from none up to a quarter. Corner radius runs from 0 to 48 px and applies to the screenshot, or to the window when a frame is on, never to the background. The shadow has three steps: none, soft and strong. For the frame you can choose none, a macOS window with its three coloured dots, or a browser window with an address bar you can leave empty or type a URL into. There is no phone frame: drawing each vendor's device outline accurately raises trademark questions we would rather not take on.
Aspect ratios and what 2× really does
Auto keeps the canvas just large enough for the screenshot and its padding. The fixed presets, 16:9, 1:1, 4:5, 9:16 and 1.91:1, cover the shapes social cards and feeds expect; the canvas grows to that shape and the extra space is split evenly, so the screenshot stays centred and is never shrunk. Export is PNG at 1× or 2×. To be clear about 2×: everything on the canvas is drawn at twice the size, which makes the frame, the shadow and the address-bar text crisper on high-resolution displays, but the screenshot itself does not gain detail it never had. JPEG is offered only when the background is opaque, because JPEG has no transparency. You can also copy the result straight to the clipboard where the browser allows writing images to it; where it does not, the button is disabled and says why.
Redact first, then beautify
This page does not hide personal data. If the screenshot shows names, emails or tokens, open the screenshot redaction tool first, black out what needs hiding, and press "Beautify this screenshot" there: the already-redacted, flattened image arrives here in one step, and refreshing this page will not bring it back a second time. The other order, beautifying first and redacting afterwards, is the wrong one, so it is not offered. The style you used last is remembered in this browser only and falls back to the defaults when storage is blocked. Exported files carry no EXIF, because a canvas export never does. Very large screenshots, such as a full-page capture, can exceed the browser's canvas limit (about 16.7 million pixels, or 32,767 px on a side) once padding and 2× are added; the page then falls back to 1× or, when even that will not fit, declines and tells you the reason.
