Where is the circle mask applied?

In your browser. The Canvas API clips the selection with an arc() path and saves the corners as transparent PNG pixels, all inside this tab. Our servers are not involved at any point.

Why must I download as PNG?

PNG supports transparency and JPEG does not. The circular mask needs transparent corners, which only PNG can keep.

Can I use the circle crop as a profile photo?

Yes. The transparent PNG works as a profile photo or avatar on any platform that shows images on a background. Most social platforms also accept standard square photos and apply their own circular mask.

Will the circle crop be perfectly round?

Yes. The tool locks the crop to a 1:1 aspect ratio and applies a CSS circle clip in the preview, then renders a circular canvas clip on export.

Crop image to circle

Crop your image to a circle using the Canvas API, entirely in your browser. The corners outside the circle are saved as transparent pixels in a PNG, so the round image sits cleanly on any background.

Drop an image or click to browse

JPEG, PNG, WebP. Runs in your browser.

How it works

The tool reads your image into browser memory and displays it in an interactive crop preview. Drag the crop box to reposition it, or pull the corner handles to resize. When you click Crop & download, the Canvas API draws the selected region to an offscreen canvas in your browser tab and exports it as a file.

Processing runs in your browser

The Canvas API processes the crop operation locally, and the resulting file is downloaded directly to your device. Our servers are not involved at any point.

Related operations

After cropping, scale the result with resize image. To switch the saved format, use the image converter. For turning a sideways photo upright before cropping, see image rotate.
