SPINX Digital

<p>Convert JPEG, PNG & GIF to WebP and bulk-optimize your Media Library entirely on your own server. No external services. No data sent. No quotas.</p>
<h3>🚀 Local-First WebP Conversion For WordPress</h3>
<p><strong>SPINX Digital Image Converter</strong> generates lightweight WebP versions of your JPEG, PNG, and GIF uploads — including every WordPress-generated thumbnail size — so your pages load faster and your images stay lighter.</p>
<p>Unlike cloud-based optimizers, <strong>all processing happens on your own server</strong> using PHP’s GD or ImageMagick extension. Nothing is uploaded to a third party, no account is required, and there are <strong>no monthly limits or quotas</strong>. Your images never leave your hosting environment.</p>
<p>It’s built for site owners who want faster image delivery, a safe and reversible workflow, and a clear, honest view of exactly what was converted, skipped, restored, or failed — all from a single dashboard.</p>

SPINX Digital Image Converter

Convert JPEG, PNG & GIF to WebP and bulk-optimize your Media Library entirely on your own server. No external services. No data sent. No quotas.

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>
<h3>Minimum Requirements to use CompressX</h3>
<ul>
<li>Character Encoding UTF-8</li>
<li>PHP version 7.0</li>
<li>MySQL version 4.1</li>
<li>WordPress 5.8</li>
</ul>
<h3>External Services</h3>
<p>This plugin optionally connects to the <a href="https://api.cloudflare.com/" rel="nofollow ugc">Cloudflare API</a> to purge your CDN cache. It sends the Cloudflare Zone ID, account email, and Global API Key whenever the “Purge Cloudflare Cache” button is clicked or automatically upon optimization completion (if enabled in settings).

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 🙏
