CSS Circular Cropping of Rectangle Image

Question

I want to make a centered circular image from rectangle photo. The photo's dimensions is unknown. Usually it's a rectangle form. I've tried a lot of methods:

Code

.image-cropper {
    max-width: 100px;
    height: auto;
    position: relative;
    overflow: hidden;
}

.image-cropper img{
    display: block;
    margin: 0 auto;
    height: auto;
    width: 150%; 
    margin: 0 0 0 -20%;
    -webkit-border-radius: 50%;
    -moz-border-radius: 50%;
    -ms-border-radius: 50%;
    -o-border-radius: 50%;
    border-radius: 50%;  
}

<div class="image-cropper">
   <img src="https://sf1.autojournal.fr/wp-content/uploads/autojournal/2012/07/4503003e3c38bc818d635f5a52330d.jpg" class="rounded" />
</div>

Answer 1

The approach is wrong, you need to apply the border-radius to the container div instead of the actual image.

This would work:

.image-cropper {
  width: 100px;
  height: 100px;
  position: relative;
  overflow: hidden;
  border-radius: 50%;
}

img {
  display: inline;
  margin: 0 auto;
  height: 100%;
  width: auto;
}

<div class="image-cropper">
  <img src="https://via.placeholder.com/150" class="rounded" />
</div>

The object-fit property provides a non-hackish way for doing this (with image centered). It has been supported in major browsers for a few years now (Chrome/Safari since 2013, Firefox since 2015, and Edge since 2015) with the exception of Internet Explorer.

img.rounded {
  object-fit: cover;
  border-radius: 50%;
  height: 100px;
  width: 100px;
}

<img src="https://picsum.photos/200/300" class="rounded">

Answer 3

If you can live without the <img> tag, I suggest you use the photo as a background image.

.cropcircle{
    width: 250px;
    height: 250px;
    border-radius: 100%;
    background: #eee no-repeat center;
    background-size: cover;
}

#image1{
    background-image: url(http://www.voont.com/files/images/edit/7-ridiculous-ways-boost-self-esteem/happy.jpg);
}

<div id="image1" class="cropcircle"></div>
