Know an image's exact size in one glance
Before uploading to a form or resizing for print, you often need to know an image's pixel dimensions. Phone galleries hide this, and opening image properties on a computer is clunky.
Drop the image here and every fact — width, height, aspect ratio, megapixels, file size and format — is read instantly in your browser. Nothing is uploaded.
