Make Round Image

Transparency Is the Part People Get Wrong

Rounding an image means masking its corners away, and that only survives in a format with an alpha channel. Export a circular crop as JPG and the corners come back as solid white or black, because JPEG has no way to record "nothing here" — which is why a circle-cropped avatar so often arrives with visible square edges. This tool defaults to PNG for exactly that reason. If you do pick JPG, the corners are filled with your chosen background colour rather than left to chance.

Nothing Leaves Your Device

This tool is drawn entirely on a canvas inside your browser. Your images are never uploaded, which means they are never queued, logged, or retained — and the tool keeps working with your network disconnected.

Key Features

• Circle or rounded-square masks, with an adjustable corner radius
• Optional border in any colour, drawn inside the canvas so it is never clipped
• Non-square images are centre-cropped to a square first, so circles stay circular
• Transparent PNG output by default, with a solid-colour fallback if you need JPG
