Crop to a perfect circle with transparent corners.

Nothing is uploaded — the file stays in your browser.

Runs entirely in your browser. Nothing you paste is uploaded, logged, or stored.

How to use it

  1. Choose the photo you want to crop.
  2. Set the output size in pixels.
  3. Optionally add a border and pick its colour.
  4. Crop and download the PNG.

What it does

Centre-crops your image to a square, then masks it to a circle so the corners are fully transparent. Output is always PNG, because a circular cutout needs an alpha channel and JPEG doesn't have one.

Where circular crops are used

Most platforms display avatars in a circle but accept a square upload, cropping it themselves. Doing it yourself matters when you need the transparent corners — overlaying a portrait on a coloured section, or putting a logo into a design where a square edge would show.

FAQ

Are my images uploaded to a server?
No. Every tool here decodes and re-encodes your file using your browser's own Canvas APIs. The image never leaves your device, which is also why it works offline once the page is loaded.
Why is the output always PNG?
The area outside the circle has to be transparent, and only PNG and WebP support transparency. PNG is chosen because it's accepted everywhere avatars are.
Can I choose which part of the photo the circle keeps?
The crop is centred. If your subject is off-centre, crop the photo to roughly square first, then run it through here.
