Can I round corners of images other than PNG?

The radius slider controls how curved the corners become; higher values create more pronounced rounding, while lower values keep corners nearly sharp.

Is there a limit to the file size I can upload?

The tool processes images directly in your browser, but very large files may take longer to handle depending on your device's performance.

Will rounding corners reduce the image quality?

The modification adjusts only the corner geometry; the rest of the PNG remains unchanged, so overall image quality is preserved.
