How to: Screenshot Mockup Generator

  1. Upload a screenshot.
  2. Choose a frame, background, padding and shadow.
  3. Download a polished PNG for slides, docs or social posts.

A raw screenshot looks unfinished in a presentation, landing page or tweet. Placing it in a browser window or device frame on a soft gradient instantly makes it look professional. Upload a screenshot, pick a frame and background, adjust padding, corner radius and shadow, and download a high-resolution image ready to share.

Common uses

Tips for best results

Frames and backgrounds

Browser frames come in light and dark versions with window controls and an address bar, the macOS frame shows only the familiar coloured buttons, and phone and tablet frames add a dark bezel with rounded corners. Backgrounds include several gradients, plain white, grey or transparent. Frame details scale with the screenshot size, so they look right on small and very large images.

Shadows and corners

A soft drop shadow lifts the screenshot off the background and gives depth, while rounded corners match modern operating systems. Set the corner radius to zero for a sharper, technical look or turn the shadow off for flat designs.

Confidential screenshots stay local

Unreleased interfaces and dashboards with real data should not be uploaded to random websites. This generator draws everything with the canvas in your browser.
