Frequently Asked Questions

Have questions? Here are the answers about Rounded Corner Image

Why are the rounded corners not transparent?

Export as PNG when you need transparent corners. JPEG does not support transparency and will fill the corner area with a background color.

How do I make a circular image?

Upload your image and click the 'Circle' preset button. This sets the corner radius to the maximum value, creating a perfect circle. For best results, start with a square image or crop it first.

Can I control the exact corner radius?

Yes! Use the custom slider to set any radius from 0px to the maximum (half the shorter dimension). You can also use the preset buttons for common sizes: Small (16px), Medium (32px), Large (64px), or XL (128px).

Does it support transparent backgrounds?

Yes! By default, the area outside the rounded corners is transparent (shown as a checkerboard pattern). The output PNG preserves this transparency. You can also choose white, black, or other background colors.

What image formats are supported?

The tool supports JPG, JPEG, PNG, GIF, WebP, and BMP input. Output is always PNG to support transparency for rounded corners.

Is image quality preserved?

Yes! The tool uses canvas rendering at full resolution. Your image maintains its original quality, only the corners are rounded.

Why does my circle crop look stretched?

Start with a square image or crop to a square before using circle mode. Non-square images can create oval-looking results.

Is my image uploaded when rounding corners?

Corner rounding runs in your browser. The selected image is not uploaded to Rune for this operation.

What's a good corner radius for app screenshots?

For app screenshots and UI mockups, 24-32px radius typically looks professional. For social media profile pictures, use Circle mode. For subtle rounding, try 8-16px.

Can I use this to make profile pictures?

Absolutely! Use the Circle preset to create perfectly round profile pictures. For platforms that accept square images with rounded display, try medium or large radius presets.
