Why Round Image Corners?

Rounded corners feel modern, soften harsh edges, and fit card-style layouts and social feeds.

Benefits

  • Modern look: Matches current UI and app design.
  • Softer edges: Less sharp than a plain square crop.
  • Consistency: Same radius across a set of images.
  • Social-ready: Works well for avatars, cards, and thumbnails.
  • Polish: Quick finishing touch before publish.

Corner style

Five shapes, from a soft curve to a square notch. Round gives a true circular curve.

  • Round A true circular curve — the classic rounded corner.
  • Squircle The continuous curve used across app icons.
  • Chamfer A straight diagonal cut across each corner.
  • Scoop A circular bite taken out of each corner.
  • Notch A square notch removed from each corner.

2 is exactly a circle. 4 is the classic squircle. Higher is closer to a square.

How Corner Rounding Works

A rounded-rectangle mask clips your image; pixels outside the curve use your background or transparency.

Processing steps

  • Load Image data is read straight from the file.
  • Radius Corner radius is applied uniformly on all four corners.
  • Mask Content inside the rounded shape is kept.
  • Background Transparent or solid fill outside the image area.
  • Export Encode to PNG, JPEG, or WEBP.

Corner radius guide

Pick radius based on image size and how rounded you want the look.

Radius values

  • Subtle (about 5–10px) Light softening; still mostly square.
  • Moderate (about 10–20px) Clearly rounded—common for web cards and social.
  • Strong (about 20–40px) Bold rounding on larger images.
  • Very strong (40px+) Approaches pill-like shapes on small canvases.

Frequently asked questions

How do I make a profile picture with rounded corners?

Upload your photo, set the corner radius with the slider, and export as PNG with a transparent background. The transparent PNG format lets your rounded image sit cleanly on any background color—ideal for Instagram, LinkedIn, or site avatars.

What radius setting creates a perfect circle from a square image?

Set the radius to half the image’s shorter dimension—for a 400×400 image, drag the slider to maximum or use roughly 200px. Download as PNG with a transparent background to preserve the circular shape without a white box behind it.

Can I round corners on a PNG and keep the background transparent?

Yes—select Transparent as the background option and export as PNG. Avoid JPEG for rounded corners since that format does not support transparency and will fill the rounded areas with white. WEBP also supports transparency if you need a smaller file size.

Why do my rounded corners show a white box in Canva or PowerPoint?

The white box appears when the image was saved as JPEG, which does not support transparent backgrounds. Re-export as PNG or WEBP with the Transparent background option selected, and the rounded cutout areas will be invisible on any background.

Can I apply rounded corners to multiple images at once?

Yes, with Pro. Drag several images in at once, set the radius and background once, then press Round corners to apply the same settings to every image. Each result has its own Download button, and once two or more are finished, Download all collects them into a single ZIP. On Free the tool rounds one image at a time.

Does rounding corners reduce image quality or resolution?

No—corner rounding clips the image shape without touching or compressing the pixels inside the rounded area. Exporting as PNG keeps full lossless quality. If you use JPEG export, set quality to 90–100% to avoid visible compression artifacts near the edges.
