Add Rounded Corners and a Shadow to an Image

About this option

Rounded corners and a soft shadow make a picture lift off the page — a look used in app stores, slides and product pages. This page opens the mockup tool with a transparent background, 20-unit corners and a drop shadow, so you can place the PNG over anything.

When to use it

  • Preparing an image to overlay on a coloured slide or web page
  • Giving product photos a clean, card-like appearance
  • Creating app-store style screenshots with rounded corners

How to use it

  1. 1Drop your image — transparent background, rounded corners and shadow are preselected
  2. 2Adjust the corner radius, shadow strength and padding
  3. 3Download as PNG to keep the transparency

Frequently asked questions

Why is PNG recommended?

Rounded corners and the shadow sit over a transparent background, which PNG and WebP can store but JPEG cannot.

How much padding do I need?

Leave enough room around the picture for the shadow to fade out; raise Padding if the shadow looks cut off.

Can I add a coloured border too?

Yes. Use the Border controls to add an outline of any colour and thickness.
