About the Round Image Corners

The ByteTools Rounded Corners tool softens the sharp edges of any image, rounding all four corners by the radius you choose. The rounded area becomes transparent, so the picture sits perfectly on cards, buttons, app tiles and web layouts that use rounded shapes.

Drag the radius slider from a subtle curve to a fully pill-shaped image and watch the preview update instantly. It is ideal for UI mockups, thumbnails, avatars and product images that need a modern, softened look.

Processing is entirely local — the rounding is drawn on an HTML canvas in your browser. Your image is never uploaded, keeping designs, screenshots and personal photos completely private.

Frequently asked questions

How do I round the corners of an image?

Upload the image and drag the radius slider until the corners look right, then download the PNG. The rounded areas are transparent, so the image fits neatly into cards and rounded layouts.

Why does the rounded image need to be a PNG?

Rounded corners require transparency in the areas that are cut away, and only formats like PNG support transparency. Saving as JPG would fill those corners with a solid color and remove the rounded effect.

Can I make a fully rounded, pill-shaped image?

Yes. Increase the radius to its maximum and the shorter sides become fully rounded, producing a pill or stadium shape. Lower values give a gentle, modern corner curve instead.

Are my images uploaded to round the corners?

No. All rounding is done locally in your browser with the canvas API. Nothing is transmitted to a server, so your images stay private on your device.
