Pro Tips
- •The corners are made transparent, not filled with a color - the result is always downloaded as PNG to preserve that transparency
- •A radius set to half the image's shorter side produces a fully circular or stadium-shaped result
- •The checkered pattern in the preview represents transparency, not part of the actual image
- •The whole file is processed locally in your browser - nothing is uploaded anywhere

How It Works
Read the uploaded image and decode it using the browser's native image support
Draw a rounded-rectangle clipping path onto a new canvas based on the selected radius
Draw the image through that clip, which discards anything outside the rounded shape
Encode the canvas as PNG, preserving the transparent rounded corners

Frequently Asked Questions
Why is the output always PNG?
Rounding the corners makes the area outside the rounded shape transparent. JPG doesn't support transparency, so PNG is used to preserve the rounded-corner effect correctly.
Can I get a fully circular image?
Yes. Set the radius to at least half of the image's shorter dimension to round it into a full circle or stadium shape.
Is my image uploaded to a server?
No. The entire process runs locally in your browser using the Canvas API. Your image never leaves your device.
Will the transparent corners show as white or black?
Neither, by default - they're truly transparent. They'll only appear as a color if you place the image on a colored background afterward.
Can I round only some corners?
This tool rounds all four corners equally. For rounding individual corners differently, you'd need an image editor with more granular path controls.
