<h4>WordPress Image Optimizer</h4>
<p>Optimus reduces the file size of uploaded media files automatically. Depending on the image and format, reductions in size of up to 70% are possible. Several kilobytes can be saved per image—these savings contribute positively to the performance of the blog website. What’s most impressive about the compression technology: the quality of the images is maintained.</p>
<blockquote>
<h4>There are three different versions of Optimus:</h4>
<ol>
<li><strong>Optimus</strong> <em>(Free)</em> as base version with limitations (e.g. max of 100kb)</li>
<li><strong>Optimus HQ</strong> <em>(Premium)</em> with expanded functionality for personal projects</li>
<li><strong>Optimus HQ PRO</strong> <em>(Premium)</em> as professional solution for customer websites</li>
</ol>

<h4>How does it work?</h4>
<p>During the uploading process of images to the media library, the <em>Optimus</em> plugin simultaneously sends the images to the <em>Optimus</em> server, where the incoming material is processed and sent back in optimized form. Afterwards, the <em>Optimus</em> plugin saves the image version with a reduced file size in the media library.</p>
<p>The optimization of images – <em>including thumbnails</em> – is conducted in the background and outside of the view of the user. The image compression gains per file are displayed by Optimus within the media library in form of a percentage value, see <a href="https://wordpress.org/plugins/optimus/screenshots/" rel="ugc">screenshot</a>.</p>
<p>Superfluous information that is saved by image processing programs and is not even necessary for displaying the image is extracted from image files. This way, the quality of the graphics remains intact while the image size can be reduced significantly. If you wish, Optimus keeps all author, EXIF and copyright information contained within the photos — the compressional gains will be correspondingly lower.</p>
<p>Optimus supports the conversion of images to the new <a href="https://www.keycdn.com/blog/convert-to-webp-the-successor-of-jpeg" rel="nofollow ugc"><em>WebP</em> image format</a>.</p>
<blockquote>
<p>It is recommended to use the <a href="https://wordpress.org/plugins/cache-enabler/" rel="ugc">WordPress Cache Enabler</a> plugin to integrate the converted WebP images.</p>

<h4>Tips</h4>
<ul>
<li>Photos should always be saved as JPEGs rather than PNGs. The PNG format works well for illustrations, JPEG on the other hand is the right choice for photographs. Another reason: the size reduction always works more quickly for JPEGs.</li>
<li>Your images have been optimized using Desktop tools such as ImageOptim (Mac) or PNGGauntlet (Win) before you upload them? Optimus has the significant benefit of also minimizing the thumbnails (=preview images) created by WordPress. After all, themes almost always integrate thumbnails rather than original images.</li>
