How to use Rounded Corner Image online

Use these steps to add rounded corners to an image and confirm the transparent or filled edge before downloading.

  1. 1

    Add your file

    Upload one square or rectangular image. Rune reads the image dimensions, opens the controls, and scrolls you toward the radius settings after the preview loads.

  2. 2

    Adjust settings

    Pick a preset such as Small, Medium, Large, XL, or Circle, or use the custom radius slider for an exact pixel value on the image.

  3. 3

    Export the result

    Check the preview over the checkerboard or selected background color, then download the PNG when the corner shape works for your final design placement.

Preset corner radius

Use None, Small, Medium, Large, XL, or Circle presets when you need common rounded-corner looks without guessing radius values.

Custom radius slider

Fine-tune the corner radius in pixels up to half the shorter image side, which prevents impossible corner values.

Transparent corner preview

A checkerboard preview makes transparent corners visible, helping you confirm the PNG will sit cleanly on another background.

Solid background choices

Choose transparent, white, black, light gray, or dark fill when the final platform does not handle transparent corners well.

PNG output for design use

The exported PNG preserves the clipped corner shape and keeps the original image available for comparison or another radius pass.

Avatar and card checks

Preview circle crops, app screenshots, product cards, and thumbnail edges at a useful size before placing the image in a layout.

Rounded Corner Image privacy and processing

Rounded Corner Image explains how the selected file is clipped in the browser, why PNG is used, and which corner checks matter before publishing.

Processing Browser

The selected image is loaded in your browser, clipped with the chosen radius, and exported through canvas as a PNG file.

Storage None

The image, radius setting, and background choice live only in the open tab until you download the PNG or refresh.

Rounded Corner Image account access

You can round image corners as a guest. Keep the page open until the styled PNG has been saved.

Before You Use Rounded Corner Image

Check these Rounded Corner Image notes before preparing avatars, UI screenshots, ecommerce photos, or card images for a final layout.

Privacy

The uploaded image stays in the current tab while the rounded mask preview is drawn.

Use only images you are allowed to edit, especially when preparing client graphics, product photos, or profile pictures.

Input Quality

Start with a clean source because the rounded mask removes only the corner areas and keeps the rest of the pixels.

Circle mode works best on square images. Rectangular images become pill-shaped rather than a perfect circle.

Output

The PNG should show the selected radius and background choice exactly as shown in the preview.

Keep the original image until you confirm the rounded PNG fits the destination background and dimensions.

Limits

Rounded Corner Image works on one browser-loaded image at a time. Very large files can make radius preview and PNG export slower.

Questions about Rounded Corner Image

How do I add rounded corners to an image online?

Upload one image, choose a radius preset or move the custom slider, check the preview, and download the PNG once the corners look correct.

Can I make a circle image with this tool?

Yes, use the Circle preset. A square source becomes a circle, while a rectangular source becomes a pill shape because the original proportions are preserved.

Should I use transparent or solid corners?

Use transparent corners when the PNG will sit on different backgrounds. Use a solid fill when the destination app does not display transparency reliably.

Does Rounded Corner Image change the original file?

No. The tool creates a new PNG from the browser preview. Your original file stays unchanged on your device unless you replace it yourself.

Why does the rounded image download as PNG?

PNG supports transparent corners and keeps the canvas export predictable. If you choose a solid background, the result still downloads as PNG from this tool.
