Round Corners & Circle Crop
Round image corners with adjustable radius or crop to a perfect circle. Outputs transparent PNG. Free, private.
Round Image Corners
Round the corners of an image or crop it to a perfect circle for an avatar — both export as a transparent PNG so the cut-away areas stay see-through instead of white. Set the radius as subtle or as bold as you like; everything renders live before you download.
Radius guide
| Look | Radius |
|---|---|
| Subtle card corners | 8–16px |
| Pronounced rounded style | 24–48px |
| Full circle / pill | ≥ half the shorter side |
Options
- Corner radius — Adjustable from 0px to 200px
- Circle crop — Crops the image into a perfect circle from center
Use cases
Profile pictures, product thumbnails, social media avatars, UI design assets, and anywhere you need rounded or circular images.
Frequently asked questions
Why is the output a PNG?
Rounded corners and circle crops need transparency for the cut-away areas, and PNG supports an alpha channel while JPEG does not.
How do I make a circular avatar?
Use the circle-crop option on a square image; for a non-square photo, crop to 1:1 first for a clean circle.
Can I control how round the corners are?
Yes — adjust the radius from a subtle curve to heavily rounded corners.
Is it private?
Yes — everything runs locally in your browser.
What radius should I use?
Around 8–16px gives a subtle card-like look; 24–48px is a pronounced rounded style. A radius at least half the shorter side turns the image fully circular.
Will the rounded corners show white instead of transparent?
Only if you flatten the PNG onto a background that doesn’t support transparency. Keep it as a PNG and the cut-away areas stay see-through.
Does circle-crop work on a non-square image?
It crops to the shorter dimension, which can cut off part of a rectangular photo. Crop to 1:1 first if you want to choose exactly what stays in the circle.
Can I round corners on an image I’ve already cropped or resized?
Yes — rounding is applied last regardless of order, though doing it after cropping avoids re-rounding a shape you change afterward.
