Crop an image to a square (1:1)

Where a 1:1 square crop is required

Square is the universal profile shape. Almost every avatar slot, from social networks to messaging apps to forums, displays a 1:1 image, often masking it to a circle on top. Cropping to a clean square first means you decide what sits in that frame rather than letting the platform guess.

It is also the grid standard. Instagram grid thumbnails, marketplace listing tiles and product catalog cells line up neatly only when every image is square. Crop each one to 1:1 here, then resize them to a matching size so the grid looks deliberate.

Framing a tall photo into a square

Most phone photos are 4:3 or taller, so forcing them square means losing the top and bottom. Keep the subject centered as you size the box, and drag the middle of the selection to slide the framing until the face or product sits in the middle of the square.

If the subject hugs an edge, the square may cut it. In that case recompose by moving the box rather than shrinking it, since a smaller square throws away resolution you may want for a sharp avatar.

Square crop, then size and shape

Crop to the square here first, then finish for the destination. For a round avatar, run the square through the circle crop tool, which keeps the 1:1 shape and masks it to a transparent circle. For an exact pixel size like 400x400, use the resize tool afterward.

Everything runs on your device. The image is cropped in the browser and never uploaded, so a personal profile photo stays private from start to finish.
