Which size should I pick?

X and LinkedIn show single images in link posts at about 16:9 (1200×675 is the common export), so 16:9 avoids cropping. Instagram feed posts look best at 4:5 (portrait) or 1:1. "Fit to image" keeps the padding even on all sides and is the best choice for docs, READMEs and slides. The tool keeps your screenshot at full resolution and grows the background around it, so text stays sharp.

How it works

Your image is drawn on a canvas in this page at its full resolution: the background first, then the shadow, then the screenshot (and the window frame) clipped to rounded corners. Padding is a percentage of the screenshot's longer side, so it looks the same for a phone capture and a 4K one. With a fixed size like 16:9, the background grows on the short side until the ratio matches, so the screenshot is never cropped or squashed. Nothing is uploaded; only "Capture URL" asks our server to take the screenshot.

FAQ

Is my screenshot uploaded? No. Pasted, dropped and chosen images stay in your browser. Only the optional URL capture runs on our server, and the result comes back to this page.

Is there a watermark? No, and no signup. The PNG is yours to use anywhere.

Will text stay sharp? Yes. The output keeps your screenshot's original pixels and adds the background around it. For crisp text, start from a retina (2x) screenshot.

Can I get a transparent background? Pick "Transparent (PNG)": the padding and shadow stay, the background is see-through, which is handy for slides and docs with their own colors.
