How to know an image size in pixels

Someone asked me how do they know the image size in pixels?

Well, if uploading an image to a web application recommends 2000px * 2000px, you can know if your image has the width and height dimensions as required by following methods.

Mac users

  • On your Mac, right click on the image file, look at Get Info and click on it. On the pop-up window, expand More Info, you will be able to see the image dimensions in pixels.
  • On you Mac, open the image file in Preview. Click on the Annotations Toolbar ( the pen icon) on the top menu of the image.  Click on the Annotations List icon, a pop-up window will open. On the new window, click on the General Info Inspector tab or the More Info Inspector tab. This will show the pixel height and width of your image.
  • On your browser – Safari,  right click on the image, look at Inspect element and click on it. You will be able to see the HTML codes and CSS. Click on the <Img> tag, it will show the image dimensions.
