Round Image Corners

Round off the corners of an image and save it as a PNG with the corners cut away cleanly.

Softening a hard rectangle

Sharp ninety-degree corners can look harsh, especially in interfaces, cards and thumbnails where everything else is soft. Rounding the corners of an image gives it the gentle, modern feel that app icons, profile cards and product tiles use everywhere. You choose how much to round — a slight softening or a heavily curved edge.

Because the rounded-off corners are cut away to nothing, the result is a PNG, so it sits cleanly on any background without white triangles poking out.

Rounded corners versus a circle

This is the rectangular cousin of a circle crop. A circle crops the image to a full round shape; rounding the corners keeps the image rectangular and just softens the four corners. Reach for rounded corners when you want to keep the whole picture but lose the sharp edges, and a circle crop when you want a fully round avatar.

How to round the corners of an image

  1. Add your image.
  2. Set how rounded you want the corners.
  3. Download the PNG with rounded corners.

Soft corners, transparent edges

Rounded corners are a small detail that makes avatars, cards and app screenshots look finished rather than pasted in. Because the corners are cut away, the export must be a PNG so those areas stay transparent instead of filling with white.

Match the radius to the size of the image. A small avatar needs only a few pixels of rounding to read as soft, while a large screenshot needs considerably more before the effect is noticeable at all.

Questions & answers

Why is the result a PNG?

The cut corners need transparency, which JPG cannot store.

What radius should I use?

Enough to read at the size you will display it — small images need only a few pixels, large ones need much more.

Can I round only some corners?

This applies an even radius; uneven corners need a dedicated image editor.

Why is the download a PNG?

The rounded-off corners are transparent, and only PNG can store transparency. A JPG would fill them with a solid colour.

Can I choose how rounded the corners are?

Yes — from a subtle softening to a strongly curved edge.

How is this different from a circle crop?

Rounded corners keep the image rectangular and just soften the corners; a circle crop makes the whole image round.
