Image with imagick driver resizing into small image gives large file size
<p>I am resizing large images on my project to create thumbnails. Here is one example:</p>

<p>Original Image (1160 x 773):
<a href="https://i.stack.imgur.com/lPibh.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/lPibh.jpg" alt="Original Image (1160 x 773)"></a></p>

<p>Thumbnail (400 x 266):
<a href="https://i.stack.imgur.com/SLUVF.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/SLUVF.jpg" alt="Thumbnail (400 x 266)"></a></p>

<p>The problem is, the large image is 732kb which is I think understandable since it's size is big, but the second image is still 573kb.</p>

<p>Is this normal or is there something wrong?</p>

<p>Here is my code for resizing:</p>

<pre><code>\Intervention\Image\Facades\Image::make($originalPath)
    -&gt;resize($resized_width, $resized_height, function($constraint){
        $constraint-&gt;aspectRatio();
        $constraint-&gt;upsize();
    })
    -&gt;save($thumbnailPath, 85);
</code></pre>
