Round Image Corners
Give a rectangular image rounded corners without adding a solid background. Choose the corner radius and save a PNG with transparent corner areas.
- Adjust the corner radius proportionally
- Keep the image’s original outer dimensions
- Export transparent corner regions in PNG
Choose a radius that fits
The radius is based on the shorter image side and limited to half of it. Larger values create more pronounced rounding.
Keep the rectangular canvas
The saved file remains rectangular. Pixels outside the rounded shape become transparent rather than being replaced with white.
Place the image on your layout
Transparent corners reveal whatever sits behind the image. Check the result on the destination background, especially around light edges.
Use circular cropping when needed
Rounding a wide rectangle does not create a circular avatar. Use Circle Crop for a centered circular shape on a square canvas.
Round Image Corners FAQs
Some viewers display transparency over white. Check it against a colored background or transparency grid.
JPG cannot retain alpha transparency. Keep PNG when the corner areas must remain transparent.
JPG has no transparency, so an editor must fill the removed corner areas with a color. Keep the PNG output when placing the rounded image over different backgrounds. Use a separate background fill only when a flattened rectangular file is intended.
