Frequently Asked Questions

Upload your image (drag & drop or click). Use the slider to set the corner radius. By default all corners change together; turn off the lock switch to adjust each corner individually. Click “Download Rounded Image” to get the final result.

Yes. The downloaded PNG has a transparent background by default. You can also choose a white, black, or custom background color from the settings panel.

JPG, PNG, GIF, BMP, WebP, and SVG can be uploaded. The tool always exports a PNG with true rounded corners (real clipping, not just CSS).

No. The original width and height are preserved. Only the corner pixels are clipped. The output dimensions stay the same.

There is no strict limit, but very large images (above 5000px) may slow down preview. For a smoother experience we suggest images under 4000px.

Absolutely. If your image is square, click the “Max Round” preset (or set the radius to half the image width). The result will be a perfect circle.

Yes. The live preview uses CSS for instant feedback, but the downloaded file is generated with a canvas‑based clipping path, so the corners are truly rounded – ideal for further use or print.

The preview respects your screen size and may scale the image. The download always uses the original resolution with precise pixel‑based corner radius. If you set a radius larger than half the image dimension, it will be capped automatically in the download.
