How to use this tool

  1. Add your screenshot

    Drop a file, paste with Ctrl+V, or tap to pick one — PNG, JPG and WebP all work, and nothing is uploaded.

  2. Style the scene

    Pick a background and canvas size (16:9, 4:5, 1:1 or 3:2), then tune padding, corner radius, shadow and the optional macOS window frame.

  3. Export at 2×

    Download a retina-sharp PNG or copy it straight to your clipboard, ready to paste into a post or a doc.

Questions people ask

How do I make a screenshot look better for social media?

Four things do most of the work: padding around the image, slightly rounded corners, a soft shadow, and a background with some colour. This tool applies all four at once and lets you fine-tune each with a slider.

Does my screenshot get uploaded anywhere?

No. The image is composed on an HTML canvas inside your browser; there is no upload endpoint at all, and the tool keeps working if you go offline after the page loads.

What export sizes are supported?

16:9 (3840×2160), 4:5 (2160×2700), 1:1 (2160×2160) and 3:2 (3240×2160) — each preset exports at twice its base size so text in the screenshot stays sharp on retina displays.

Can I add a window frame with the three dots?

Yes — a macOS-style title bar with traffic-light dots, in light or dark, with an optional window title. It is drawn as part of the canvas, so it exports at full resolution.

Can I paste a screenshot instead of saving it first?

Yes — take the screenshot, then press Ctrl+V (Cmd+V on Mac) anywhere on this page. The image loads straight from your clipboard without ever touching your disk.

Can I remove the "made with dynamb" mark?

Yes — it is a single checkbox, free, with no signup. Leave it on if you feel like sending someone else our way.
