Circle Crop Image

How it works

The largest possible square is cropped from the center of the image, then masked to a circle. The output is always a PNG, since the transparent corners outside the circle need an alpha channel that JPEG doesn't support.

The size follows the shorter side of your photo, with nothing scaled. A 4000 × 3000 pixel picture becomes a 3000 × 3000 pixel circle, and the preview shows a checkerboard behind it so you can see which areas are transparent.

When to use it

Round crops suit profile pictures, team and author photos, and avatars. Many sites and apps apply their own round mask to whatever you upload, so check whether a normal square image is what they want before you upload a circular PNG.

Limits

The crop is always centered. If the face or subject sits off to one side, trim the image first with the Crop Image tool so the subject is in the middle. There is no border or feathered edge, and a PNG is usually larger in file size than the JPEG it came from. Some sites flatten transparency to a solid background. The image is processed in your browser and is never uploaded.

Tips for a good result

Start with a source image where the face or subject is already near the middle, and use a reasonably high-resolution original, since the circle's diameter equals the shorter side of the photo. If you need a smaller avatar, run the finished PNG through the Resize Image tool afterward; because the file is a PNG, the transparent corners are kept.
