<p>Winsite Image Optimizer will compress your images for optimal file-size while keeping its quality (pretty much) intact, using the ImageOptim API (and other processing engines coming up soon).</p>
<p>You can also process all of your old images retroactively using our dedicated tool, found under the Media section.</p>
<p><strong>Currently-implemented Image Processing Services:</strong></p>
<ul>
<li><a href="https://imageoptim.com/api" rel="nofollow ugc">ImageOptim</a> (You’ll need to obtain an <a href="https://im2.io/register" rel="nofollow ugc">API key</a>)</li>
<li>Send your suggestions on our <a href="https://github.com/win-site/winsite-image-optimizer/issues" rel="nofollow ugc">GitHub issue tracker</a>.</li>
</ul>
<p><strong>Warning</strong>: This won’t work on localhost in some cases, since some services work in a way that they pull images in from your site. This is why you’ll need a public URL in order to make this work locally.<br />
You can use a service such as ngrok to achieve that, in conjunction with this filter:</p>
<pre><code>add_filter( 'wsi_siteurl_override', function( $siteurl ) {
    return 'http://ae190611.ngrok.io/path-to-wp-installation/';
} );
</code></pre>
<p>We’d love to recieve contributions / suggestions from you on our <a href="https://github.com/win-site/winsite-image-optimizer/" rel="nofollow ugc">GitHub project</a>.</p>


Winsite Image Optimizer

Better optimization it's so important for websites. This useful plugin work out of the box with minimum attention and maximum optimization.



Work like a charm!

I have been looking for a reliable image compression tool for WordPress for a long time.. Finally found this one that actually does what it should and does it great. Big shout out to the developers!!!



Awesome !

I can't recommend this plugin as it changed lots of file names and duplicated images.

With some regex I managed to get rid of some of its damage, but with large sites this would have been a nightmare

I would say avoid this plugin to be safe, there are better plugins out there for image compressions

Changed all image file names + weird redirects

The plugin worked good and I've been using it for two years. Some of it's functions are basic and it does rename images, which has been a nuisance for me. I had to use another plugin - Media file rename to remove wsi-imageoptim- prefix from filenames (Google uses image filenames for indexing). But there is a saying: you don't look in teeth a horse which was given to you for free. Therefore three stars.
