Circle Crop Image
Crop any photo into a clean circular image with transparent corners.
Crop a Photo into a Circle
The tool centers the largest possible square inside the source image, applies a circular mask and exports the result as PNG so transparent corners are preserved.
Example
A 1600 × 1200 photo uses a centered 1200 × 1200 square before the circular mask is applied. The downloaded PNG is therefore 1200 × 1200.
Factors That Affect the Result
The shortest image dimension determines the output size. Because the crop is centered, subjects near the outer edges may be removed. PNG is used because JPEG cannot preserve the transparent area outside the circle.
Frequently Asked Questions
Why is PNG used?
PNG preserves the transparent corners around the circle.
Does the tool stretch the image?
No. It crops a centered square and keeps the original proportions.
Is the photo uploaded?
No. Processing runs locally in your browser.

Preparing a Circular Image Crop
A circle crop masks an image into a round shape, which is commonly used for avatars, profile photos, team directories and interface icons. The source image should leave enough space around the subject because the corners of the original rectangle will be removed. A square source is usually easiest to position, but rectangular images can also be cropped after choosing the focal area. If the exported format supports transparency, pixels outside the circle can remain transparent; formats without transparency may use a solid background instead. Check the output at the final display size because fine details near the edge can become difficult to see in small avatars. Keep the uncropped original so you can create different framing later without losing pixels that were removed from the circular version.
Technical Details and Practical Limits
A circular crop masks pixels outside an inscribed circle. The usable diameter is limited by the shorter image dimension unless the source is cropped first, and transparent corners require an output format that supports alpha transparency.
