CompressX

<p>CompressX is a free, lightweight WebP & AVIF conversion and media replacement plugin for WordPress. It allows you to easily convert JPG and PNG images to WebP and AVIF formats, compress WebP and AVIF images, and replace media files without changing their URLs or attachment IDs. All AVIF and WebP conversions are performed locally on your web server.</p>
<h3>Core Features</h3>
<h4>1. Convert AVIF & Compress AVIF</h4>
<p>Convert jpg, png, and WebP images on your WordPress website to AVIF format, and compress AVIF images according to the compression level you set.<br />
If the original image is already in AVIF format which is supported since WordPress 6.5, the original AVIF image will only be compressed.</p>
<h4>2. Convert WebP & Compress WebP</h4>
<p>Convert jpg, png images on your WordPress website to WebP format, and compress WebP images according to the compression level you set.<br />
If the original image is already in WebP format which is supported since WordPress 5.8, the original WebP image will only be compressed.</p>
<h4>3. Media Replacement & Auto Re-Optimization</h4>
<p>Safely replace an existing media file without changing its URL or attachment ID. When a new image is uploaded as a replacement, the system automatically regenerates thumbnails, applies your configured format conversion and compression rules, resizes where needed, and re-optimizes the file.</p>
<h4>4. Exclude Folders</h4>
<p>Select specific folders in your media library and prevent images inside them from being processed.</p>
<h4>5. Custom Folders</h4>
<p>Select folders that are in the wp-content folder but outside the Uploads (media library) and process images inside them.</p>
<h4>6. Auto-Process New Images</h4>
<p>Automatically convert new images uploaded to a WordPress website to WebP/AVIF format and compress WebP/AVIF images upon upload.</p>
<h4>7. Auto-Remove Large Images</h4>
<p>Automatically remove converted AVIF/WebP images when they are larger than original images.</p>
<h4>8. Restore Original Images</h4>
<p>Your images will be reverted to their original state and all AVIF/WebP images and data in the database generated by CompressX will be removed when CompressX is uninstalled.</p>

</ul>
<h3>External Services</h3>

CompressX — AVIF & WebP Converter, Media Replacement


It's all new, but I believe this can go far ! I was looking for a plugin with free AVIF conversion, and locally hosted (a lot of images plugins use their servers to compress, that's why a lot of them are expensive).Awesome support, totally free (for now ?), does the same thing as the famous Media Converter, but with free AVIF. Take my 5/5 rating ;)EDIT : Oh no wait, it does more than media converter, allowing you to set a max width / height on your images :fire:


This may be my future goto plugin for image optimisation


Deserves 5-stars just for vision and generosity in making this exist!



Will give it a thorough test and post any feedback as we go.



Thank you 🙏


The world thanks you!

<h4>About the plugin</h4>
<ul>
<li>You can use your Kraken.io API key and secret on as many sites/blogs as you like. We have no per-site license.</li>
<li>All images uploaded throught the media uploader are optimized on-the-fly. All generated thumbnails are optimized too.</li>
<li>The main image upload can be optionally resized – this is useful for preventing user uploads with unnecessarily large dimensions. You can specify the maximum width and/or height in Kraken.io->Settings.</li>
<li>When restricting the maximum dimensions of the main image using the resizing feature, the resulting image is <strong>enhanced</strong> using various advanced techniques, to help prevent downsample artifacts and “haloing” and produce a sharper result.</li>
<li>You can optionally preserve one or more of the Date, Copyright, Geotag, Orientation, Profile EXIF metadata tags.</li>
<li>Images can be automatically oriented according to their EXIF Orientation value – no need to manually rotate images.</li>
<li>All images already present in the media library can be optimized individually, or using the Bulk Action menu “Krak ’em all” feature.</li>
<li>This plugin does not require any root or command-line access. No compilation and installation of any binaries is necessary.</li>
<li>All optimization is carried out by sending images to Kraken.io’s infrastructure, and pulling the optimized files to your WordPress installation.</li>
<li>To use this plugin, you must obtain a full API key and secret from <a href="https://kraken.io/plans" title="Kraken.io - Plans and Pricing" rel="nofollow ugc">https://kraken.io/plans</a>. Our free account comes with a limited quota for testing our premium features, including this plugin.</li>
<li>Works great with WPEngine hosted blogs, including the staging area.</li>
<li>Since version 1.0.4, the plugin will work with local WordPress installations; the client site does not need to be published on the web.</li>
</ul>

<p>★★★★★ <strong>Excellent Option for Image Optimization</strong><br />
  “The real power of Kraken is their “intelligent lossy” optimization. I use it on all my sites and have never once needed to roll back an image because of too much quality degredation. While I hope to see some more advanced settings added to the WordPress plugin in the future, it is a perfect solution as is.” – <a href="https://profiles.wordpress.org/collinmbarrett" rel="nofollow ugc">collin</a></p>
<p>★★★★★ <strong>Quality results, quality service</strong><br />
  “The plugin works really well and effortlessly, and the support is prompt, thoughtful, and thorough. I’m hooked.” — <a href="https://profiles.wordpress.org/illustrata" rel="nofollow ugc">illustrata</a></p>
<p>★★★★★ <strong>Optimize according to Google Pagespeed</strong><br />
  “Kraken was instrumental in optimizing images to comply with Google’s Pagespeed analyzing tool. Our travel blog travelmemo.com now sports Google’s ‘mobile friendly’ tag for mobile searches” — <a href="https://profiles.wordpress.org/qualterio" rel="nofollow ugc">Walter Schaerer</a></p>
<p>★★★★★ <strong>Perfect solution to speed up site!</strong><br />
  “I love this plugin! All the questions I had are quickly responded to and I see a huge saving with image size without losing the quality. I highly recommend this plugin!” — <a href="https://profiles.wordpress.org/ezone69" rel="nofollow ugc">ezone69</a></p>
</blockquote>
<p>Once you have obtained your credentials, from your WordPress admin, go to the Kraken.io settings page. The from there you can enter your API credentials, and select your optimization preferences. Once you have done this, click on <strong>Save</strong>. If everything is in order, it will simply say “settings saved” and give you a reassuring green tick that your credentials are valid. You can now start optimizing images from within Media Library. Any image you upload from now on, through any of the media upload screens will be optimized on-the-fly by Kraken.io.</p>
<p>For advanced users, there is a third party WordPress Command Line Interface (CLI) tool to allow image optimization from the command line, or by using cron. For details, visit: https://github.com/tillkruss/wp-cli-kraken</p>
<p>Please send bug reports, problems, feature requests and so on to support (at) Kraken dot io, or directly to the author of this plugin.</p>

Kraken.io Image Optimizer

- It works with 1 image but not at Google PageSpeed standard
- It doesn't work with bulk action
- The worst thing is I inputted my credit card there and they refused to let me cancel my subscription, what a very bad thing from kraken.io

Does not work for bulk actions, subscription cannot be cancelled

As others are noting here, their customer service is terrible. In fact I'd use the word "non-existent".

After signing up with an account I decided that the service was no longer what I needed and contacted them to delete my account. Multiple times, in different ways, I've contacted their customer support about this and never had a response. Currently breaching GDPR rules, they're going to be reported.

Thank goodness I never handed over any payments to them.

Terrible Customer Service

This plugin allows you to optimize your WordPress images through the Kraken.io API, the world's most advanced image optimization and resizing API.
