<p>After installing the plugin, you can optimize your entire Media Library with a single click — no further action required. When image optimization finishes, every visitor will automatically receive new images with significantly reduced file sizes.</p>
<p>As of today, over 95% of users use browsers that support the WebP format. The loading time of your website depends to a large extent on its weight and the level of image optimization. <strong>Using our WebP Converter, now you can and speed up it in a few seconds without much effort!</strong></p>
<p>This will be a profit both for your users who will not have to download so much data, but also for a server that will be less loaded. Remember that a better optimized website also affects your Google ranking. Image optimization is very important.</p>
<h4>AVIF support</h4>
<p>Now in <a href="https://url.mattplugins.com/converter-readme-avif-support-upgrade" rel="nofollow ugc">the PRO version</a> you can use AVIF as the output format for your images. The AVIF format is a new extension — is the successor to WebP. <strong>Images converted to the AVIF format weigh about 50% less than images converted only to the WebP format</strong>, while maintaining better image quality.</p>
<p>Enjoy peace of mind knowing that AVIF is supported by over 90% of browsers. And if any visitor has an older browser, our plugin will automatically fall back to WebP — so every user gets fast, high-quality images without a hitch.</p>
<p>Unlock the magic of AVIF in our PRO version — <a href="https://url.mattplugins.com/converter-readme-avif-support-upgrade-2" rel="nofollow ugc">upgrade today</a> for unparalleled image performance.</p>
<h4>How does this work?</h4>
<p>When a browser tries to load an image file, the plugin checks if it supports the AVIF format (if enabled in the plugin settings). If so, the browser will receive the equivalent of the original image in the AVIF format. If it does not support AVIF, but supports the WebP format, the browser will receive the equivalent of the original image in WebP format. In case the browser does not support either WebP or AVIF, the original image is loaded. <strong>This means full support for all browsers.</strong></p>
<p>A guide on how to test whether the plugin is working properly can be found <a href="https://mattplugins.com/docs/how-to-test-converter-for-media-plugin" rel="nofollow ugc">here</a>.</p>
<h4>Additional information</h4>
<ul>
<li>If you have just installed the plugin, you can optimize images with <strong>one click</strong>. Image size will be smaller after generate AVIF and WebP!</li>
<li>New images that will be added to the Media Library will be converted <strong>automatically</strong>.</li>
<li>Our image optimizer does not modify your original images in any way. <strong>This means security for you and your files.</strong> Files converted to AVIF and WebP format are saved in a separate directory: /wp-content/uploads-webpc/.</li>
<li><strong>You lose nothing</strong> – if you had to remove the plugin, it will remove everything after itself. It does not leave any trace, so you can check it with ease.</li>
</ul>

Converter for Media – Optimize images | Convert WebP & AVIF


Easy to setup, works flawlessly and the author responded quickly to my php customisation request.


Great plugin with fast support

Very good plugin I can only recommend.


Extraordinary! There is no other word to define this plugin. It does everything it promises and more.



I had already used other plugins, but this one is by far the best. Even in the free version, it speeds up the site a lot. I always upload my already optimized images and installing the plugin in the free version, it improved by at least 50% converting the images to WebP.



After I saw these advantages, I purchased the PRO version, which improved the weight of the images even more (at leastleast 30% by converting images from WebP to AVIF).



What can I say more? Worth every penny invested!


Extraordinary! Simply the best!


The plugin works very quickly, is stable, and delivers what it promises. Thank you Matt!


Top quality plugin and support!


Świetna wtyczka. Używam jej we wszystkich stworzonych przeze mnie witrynach


Świetna wtyczka

Good plugin

Just works

Good job


Just as simple plugin that does its work, no drama, no unneeded UI elements, and efficient. 



Thank you for this. 


Appreciation Post


The plugin is titled "Converter for Media - Optimize images | Convert WebP & AVIF", except it doesn't actually convert images to AVIF.  That's a paid only feature.  I have not problem with freemium plugins, but you shouldn't be putting plugins in the .org directory with misleading titles and descriptions claiming to do things they can't without paying for a different version.


Doesn't do what it says


It's the easiest solution for converting images to webp I ever saw. Great job.I had some pics that didn't convert to webp, but I then used a online-converter to fix the "worst misses". Then the plugins solution for filestorage is very easy to understand and a manual replace of not converted files is quite easily done.


Perfect solution for webp

not even a trial of avif? really? zero star.


Thank you very much for creating this plugin and I am happy that someone was able to produce a plugin for WordPress with such attention to detail that works perfectly in all respects. Unlike other plugins, if there is an error on the side of the host or server, it shows and it is well organized both in coding and in producing images and saving in a folder outside the main folder of images, which makes the plugin the best because it causes The main folders are not dumped. It is also excellent in converting images of plugins and templates


The best Converter for wordpress images

Enfin une extension qui fonctionne.

Good compression and fast processing


I've been using it for 3 years now and I'm always enthusiastic about it. It gets better from update to update. Keep up the good work, Mateusz.


Absolute top plugin


I had a disappointing experience with their customer support. When I reached out for help, I was met with responses that felt dismissive and unprofessional. As a developer, I value respectful and constructive communication, especially when troubleshooting issues. Unfortunately, that was lacking here.



I hope the team takes this feedback seriously and works on improving their support interactions. A good product deserves good service.


Suggestions for improvements

Nice and easy to use

Smush – Image Optimization, Compression, Lazy Load, WebP & CDN

Thank you for taking over half of the WordPress dashboard with your giant ad. It motivated me to remove your plugin and install EWWW Image Optimizer instead.

Huge black friday Ad. Stop advertising on my dashboard.


Unfortunately, it does not support WordPress Multisite and Arabic Language.
