seopix

SEOPix optimizes your WordPress images for SEO in one click. When you upload an image, AI analyzes it and:
<ul>
<li>Compresses — up to 90% smaller without quality loss</li>
<li>Renames — generates SEO-friendly filenames based on image content (e.g. IMG_4523.jpg → vintage-leather-bag.webp)</li>
<li>Generates alt-text — descriptive, keyword-rich alt-text in 7 languages</li>
<li>Converts format — WebP, JPEG, or PNG</li>
</ul>
Works automatically on upload or manually from the Media Library. Supports bulk optimization.
<h4>Features</h4>

<h3>External services</h3>
This plugin relies on the SEOPix API (seopix.co) to process images. Without this service the plugin cannot compress images, generate SEO filenames, or produce alt-text — all image analysis and AI processing happens on SEOPix servers, not on your WordPress site.
SEOPix API — https://www.seopix.co/api
What it is used for: compressing images, generating SEO-optimized filenames from image content using AI, generating multilingual alt-text using AI, and checking the remaining credit balance on your SEOPix account.
What data is sent and when:
<ul>
<li>When an image is optimized (either automatically on upload, manually via the “Optimize” button in the Media Library, or through the “Optimize with SEOPix” bulk action), the plugin sends a <code>POST</code> request to <code>https://www.seopix.co/api/process-single</code> containing: the image file binary, your SEOPix API token (as a Bearer token in the <code>Authorization</code> header), and the optimization options you configured in Settings → SEOPix (platform preset, output format, alt-text language, filename language, and optional max width/height). The request also includes a <code>source</code> field set to <code>"WordPress plugin"</code> so SEOPix can track plugin usage.</li>
<li>When the Media Library, Settings page, or WordPress admin bar loads (and an API token is configured), the plugin sends a <code>GET</code> request to <code>https://www.seopix.co/api/auth/extension</code> with your API token in the <code>Authorization</code> header, in order to retrieve and display your current credit balance.</li>
<li>After an image is processed, the SEOPix API returns a temporary signed URL pointing to the optimized image stored on SEOPix’s own CDN (hosted on <code>seopix.co</code>). The plugin then fetches that URL with a <code>GET</code> request to download the optimized image and replace the original in your Media Library. No additional user data is sent in this download request.</li>
</ul>
No personal information about site visitors, site administrators, post content, or any data other than what is listed above is ever transmitted. The plugin never contacts any other third-party service.
This service is provided by SEOPix (operator of seopix.co). By using the plugin you agree to the SEOPix terms and privacy policy:

Winsite

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).
You can also process all of your old images retroactively using our dedicated tool, found under the Media section.
Currently-implemented Image Processing Services:
<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>
Warning: 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. 
You can use a service such as ngrok to achieve that, in conjunction with this filter:
<pre><code>add_filter( 'wsi_siteurl_override', function( $siteurl ) {
 return 'http://ae190611.ngrok.io/path-to-wp-installation/';
} );
</code></pre>
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>.

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.

Image compression for WordPress done right.
