Round an image
Round the corners, or make a circle — never uploaded.
How it works
Three steps, and nothing leaves your device.
-
1
Drop in the photo
For a circle, a square-ish photo works best — see below.
-
2
Choose the shape
A radius from square to fully rounded, or tick the circle box for a round profile picture.
-
3
Download a transparent file
PNG or WebP, because the corners you removed have to stay transparent.
Circles, corners and transparency
- A circle needs a square frame. Drawing a circle inside a rectangle gives an ellipse. This tool crops the centre square out of a non-square photo first, so the result is a real circle — but that means the sides of a wide photo are discarded. Crop the part you want first if the subject is off-centre.
- The output has to keep an alpha channel. The corners you round off become transparent. Saving as JPG would fill them with white, which puts the corners straight back, so only PNG and WebP are offered.
- Radius is a percentage, not pixels. 100% means as round as the shape allows — a circle on a square, a stadium shape on an oblong. Using a percentage means the same setting looks right whatever size image you feed it.
- Rounded corners can disappear on a dark page. Transparency shows whatever is behind it. A rounded avatar on a background the same colour as the photo's edge will not look rounded at all — test it where it will actually be used.
Frequently asked questions
Why is my circle an oval?
It should not be — the tool crops the centre square before drawing the circle. If the subject is off to one side, crop it yourself first so the right part ends up in the square.
Why can I not save as JPG?
JPG has no transparency, so the rounded corners would be filled with white and the rounding would vanish. PNG and WebP keep them clear.
What does 100% radius mean?
As round as the rectangle allows: a circle if the image is square, a stadium shape if it is not.
