How do I crop a picture into a circle with a transparent background?

Choose your picture, position the circle and leave Output on PNG. Press Download. The saved file has a square canvas with transparent pixels outside the circle, so it can sit on another background. JPEG cannot keep transparency; choose its background colour if you need JPEG output.

How do I choose the size of the circle?

Width and Height are the circle’s diameter in source pixels. Enter equal values, such as 300 and 300, set Left (x) and Top (y) to position the circle, then press Apply pixels. The full square must fit inside the source. Use Image Resizer afterwards if you need to scale the result.

Can I make a circular profile picture or avatar?

Yes. Keep the face or logo inside the circle and save a PNG. For a service that applies its own circular mask, a square crop may be sufficient. Check the service’s upload preview because it may resize, mask or replace transparency.

Can I add a border or make an oval instead?

This preset cuts a circle and has no border control or oval mask. A rounded rectangle uses the Rounded shape, while a square without transparent corners uses Rectangle and a 1:1 ratio.

Circle Image Cropper

Open a picture and move the square selection over the area you want to keep. The Circle preset locks the selection to 1:1 and clips the corners away. Choose PNG for transparent corners, or JPEG with a background colour. You can drag the handles or enter an exact diameter as equal width and height values.

Output

A circle drawn inside a square selection, with the corners transparent in PNG. Drag a box over the picture, or drag its corners. Arrow keys move the selection and shift with an arrow resizes it, a step at a time. The numbers below are the picture's own pixels, which is what the file is cut from, so a preview shown smaller than the picture still downloads the selection at full size.

The crop is exact and the original is never altered. The box you drag is mapped back to the picture's own pixels, so the file you download is the selection at full resolution and not a scaled copy of the preview. The original is never changed. A circle or rounded crop keeps real transparency in PNG; JPEG has none, so it is filled with the background colour you pick. The picture is opened and written inside this tab, and the only thing kept between visits is the shape, ratio and format you last used.
