Crop for profiles and thumbnails
Most avatars are square (1:1) and most thumbnails are 16:9. Pick the ratio, drag to frame your subject, and download — then resize to the exact pixels a platform wants. It all happens in your browser; the original is not uploaded to our servers for processing.
Crop an image to a circle
Choose Circle to keep a round area and make the four corners transparent. Picking it snaps the selection to 1:1 first, because a circle drawn inside a rectangle that is not square is an oval — you can still drag afterwards to reframe, and the preview outlines exactly the area that will be kept.
Circle crops always download as PNG. That is not a preference: transparency needs an alpha channel, and JPEG does not have one, so a circular crop saved as JPEG comes back as a square with the corners filled in — usually white or black. WebP supports transparency too, but PNG is the safest choice for an avatar upload.
Worth knowing before you bother: most platforms that display round avatars — Slack, Teams, Google, most forums — apply the circular mask themselves and want a plain square image. Uploading a pre-cut circle to those is harmless but pointless, and if the service flattens transparency you can end up with visible corners. Cropping to a circle yourself matters when the image sits somewhere that will not mask it: a slide, a document, a print layout, or an email signature.
