Open the Img Stop Round Image Corners tool and add your images. Set the radius in percent or pixels, or choose Pill or Circle, and untick any corners that should stay square. Pick a transparent or coloured background, add an optional border, drop shadow and padding, then download PNG, WebP or JPG files – one by one or as a ZIP.
About the Round Image Corners
The Img Stop Round Image Corners tool gives photos, screenshots and product images soft rounded corners, just like CSS border-radius but saved into the image itself. The corners outside the curve become transparent, so the image sits neatly on any website, slide or app screen.
Set the radius as a percentage of the shorter side so a batch of different sizes looks consistent, or in exact pixels. Round only the top corners for a card header, make a pill shape for banners or a perfect circle for avatars, and finish with a coloured border, a soft drop shadow and some padding.

Frequently asked questions
How do I round the corners of an image?
Add the image to the Img Stop Round Image Corners tool, choose a radius and click Round the corners. Download the PNG – the corners are transparent.
Why are the corners white or black instead of transparent?
JPG cannot store transparency. Choose PNG or WebP as the output format, or pick a background colour that matches where the image will be used.
Can I round only the top corners?
Yes. Untick Bottom left and Bottom right and only the top corners are rounded.
What is the difference between % and px?
A % radius is a share of the image’s shorter side, so small and large images get the same look. A px radius is exactly that many pixels on every image.
Can I add a border and shadow?
Yes. Set the border width and colour – it follows the rounded shape – and tick Drop shadow. Padding adds space around the image.
Are my images uploaded?
