Can I crop a screenshot I just took?

Yes. Press Ctrl+V or Cmd+V anywhere on the page to paste the screenshot straight from your clipboard.

Image Cropper

Drag the crop box over your image, resize it from the corner, or type exact pixel values for X, Y, width, and height. Lock the box to a ratio such as 1:1 for profile photos, 16:9 for thumbnails, or 4:5 for LinkedIn and Instagram portraits. The crop is applied at full source resolution, so you keep every pixel inside the box.
