Frequently asked questions
- Why does my download have transparent corners?
- Rounded corners require transparency, so the output is always PNG with alpha. Convert to JPG afterwards if you need a solid-background version.
- Can I round only some corners?
- Not yet — all four corners get the same radius.
- Are my images uploaded to a server?
- No. This tool runs entirely in your browser — the image is read from your device, processed locally, and never sent anywhere. You can disconnect from the network after the page loads and it still works.
