Add rounded corners or a full circle crop to any image. Use the radius slider to dial in the curve. Output is PNG with transparent corners — they're truly rounded, not faked with a white fill. Useful for profile pictures, app screenshots, design mockups, anywhere you want softer image edges.
Why rounded corners matter in design
Rounded corners are everywhere in modern UI — app icons (iOS uses 20% corner radius), profile pictures (most platforms render circular), card layouts, image previews in messaging apps. A photo with squared edges dropped into a rounded-corner UI looks out of place. Pre-rounding the image at the source means it slots in cleanly without needing CSS tricks at the destination.
The output is a transparent PNG where the corners are actually transparent (alpha channel = 0). Drop into any background — light, dark, gradient — and the corners just look right.
How to round corners on an image
- Drop your image. JPG, PNG, WebP, HEIC. Up to 50 MP free.
- Drag the radius slider. 0 = squared (no change), 50% = pill shape, 100% = full circle. Live preview shows the result.
- Pick a preset if you want a specific look:
- iOS App Icon — 22.5% radius (iOS 7+ standard)
- Material Design — 12% radius
- Soft Card — 8% radius (typical card UI)
- Pill — 50% radius
- Circle — 100% radius (auto-crops to square first)
- Download the PNG. Transparent corners, output PNG-24 with alpha.
Rounded corners vs circle crop vs background remove
Rounded corners (this tool): the entire image stays; only the corners round off. Use for cards, app screenshots, design previews.
Circle crop (this tool, 100% radius): the image becomes a circle. Use for profile pictures.
Background Remove: cuts out the subject, removes the background entirely. Different operation — produces a free-form transparent shape, not a geometric one.
Tips for the right radius
Match your destination's UI. If you're putting the image into a Material Design card, use 12% radius. If into an iOS app, use 22.5%. If into a generic "soft card" look, 8% looks neutral.
Bigger images need bigger radius. A 1000×1000 image with 8px corners barely looks rounded. With 8% (= 80px) corners it looks intentional. Use the percentage slider rather than absolute pixels.
For circular output (profile pictures), the source image gets auto-cropped to a square first. The cropped area is centred by default; drag to reposition if you want a specific area in the visible circle.
Frequently asked questions
Are the corners really transparent?
Yes — output is PNG-24 with alpha channel. Corners are alpha=0 (fully transparent), not white-filled.
Can I make the image a perfect circle?
Yes — slide the radius to 100%. The image is auto-cropped to a square first, then rounded.
What output format?
PNG (necessary for transparency). If you really want JPG, the corners will be filled with white instead of transparent.
Does it preserve image quality?
Yes — the operation is purely a mask; underlying pixels are unchanged.
Can I round only specific corners (e.g. top two)?
Premium feature — pick which corners to round. Free tier rounds all four uniformly.
Does it work for app icons?
Yes — pick the iOS App Icon preset (22.5% radius). For full app-icon-set generation, use our App Icon Generator instead.
Maximum input size?
50 MP free. Output preserves source dimensions.
