Why use this tool
Pixels or percent
Set the radius in pixels for an exact look, or as a percentage so it scales with each image in a batch.
Circle and ellipse
Push to a full circle for square images, or an ellipse for rectangles, in one setting.
Transparent corners
Saved as PNG or WebP, the cut-away corners are transparent and blend into any page background.
Supported formats
Use cases
Circular avatars
Crop a headshot to 1:1, then make it a circle with a transparent background for an email signature or team page.
App and UI mockups
Round screenshot corners to match a phone or window frame so they look natural in a pitch deck or landing page.
Softer blog images
Give feature images a consistent 16 px radius so they match rounded cards in your site design.
Technical details
The corners are cut out with smooth, anti-aliased edges and become transparent. That’s why PNG or WebP is the right output: both formats store transparency. WebP is usually much smaller for photos, while PNG is the safest choice for places that don’t accept WebP. JPG can’t hold transparency, so in a JPG the corners are filled with a solid color that you should match to the background where the image will appear.
A full circle only stays round on a square image; on a rectangle it becomes an ellipse. For a round avatar, crop to 1:1 with the crop tool first. A percentage radius keeps corners proportional across images of different sizes, while a pixel radius gives every image the same exact curve. Pick pixels when the images will be displayed at one fixed size, such as cards in a grid, and percent for mixed batches.

Frequently asked questions
How do I make an image a circle?
Crop the image to a square first, then choose the full circle option here. The area outside the circle becomes transparent when saved as PNG or WebP. If you skip the square crop, a rectangular image becomes an oval rather than a circle.
Why are my rounded corners black or white?
The format or the app showing the image doesn’t support transparency. JPG can’t store it, so corners get a solid fill. Save as PNG or WebP instead. Some older viewers also show transparency as black or white, even when the file is correct.
Should I use px or % for the radius?
Use pixels when every image will display at the same size and you want an exact radius to match a design. Use a percentage when images differ in size, so a 5% radius looks the same on a small thumbnail and a large photo.
Will rounded corners make the file bigger?
If your original is a JPG, yes: the result has to be PNG or WebP to keep transparent corners, and PNG photos are much larger than JPG. WebP keeps the size close to the original JPG while still supporting transparency.
