PuffPix Compress automatically optimizes every image you upload to WordPress — reducing file sizes by 40–80% without visible quality loss. Faster pages, lower bandwidth, better Core Web Vitals scores.
It works by connecting to the <a href="https://puffpix.com" rel="nofollow ugc">PuffPix</a> image compression API. When you upload an image, PuffPix compresses it server-side using industry-leading encoders (mozjpeg, pngquant, cwebp) and returns the optimized file, which replaces the original in your media library.
<h4>Why PuffPix?</h4>
<ul>
<li>No server load — compression happens on PuffPix servers, not yours</li>
<li>Better results than GD — uses mozjpeg and pngquant for noticeably smaller files at the same quality</li>
<li>All thumbnail sizes — automatically compresses every generated thumbnail, not just the original</li>
<li>EXIF stripping — removes GPS coordinates and device metadata for privacy</li>
<li>Bulk optimization — compress your entire existing media library in one click with a live progress log</li>
<li>Per-image stats — see exactly how much each image was reduced, right in the media library</li>
</ul>
<h4>Compression Engines</h4>
<ul>
<li>Standard (GD) — PHP’s built-in image library. Fast and universally compatible. Quality 85 (balanced) or 72 (aggressive).</li>
<li>Pro (mozjpeg + pngquant) — significantly better compression than GD at the same visual quality. JPEGs typically 20–30% smaller than GD output.</li>
<li>Max — maximum compression using the best available encoder per format. Smallest possible file size. Requires Pro or Trial plan.</li>
</ul>
<h4>Supported Formats</h4>
JPEG, PNG, WebP, GIF. SVG support is available on the PuffPix web tool.

<h4>Privacy & External Services</h4>
This plugin sends image data to the PuffPix API for compression. Please see the “External Services” section below for full disclosure.
<h3>External Services</h3>
This plugin connects to the PuffPix image compression API to compress images.
What data is sent: 
* The image file(s) selected for compression 
* Your API key (to authenticate your plan) 
* Compression settings (engine, quality, strip EXIF) 
* Anonymous compression metrics: file format, engine, quality, bits-per-pixel range, and compression ratio (no image content, filename, or personal data)
What happens to your data: 
* Images are processed and the compressed version is returned to your server 
* Images are automatically deleted from PuffPix servers within 30 minutes 
* No image content is stored permanently 
* API keys are not logged beyond authentication
Service details: 
* Service name: PuffPix 
* Service URL: https://puffpix.com 
* API endpoint: https://puffpix.com/api.php 
* Privacy policy: https://puffpix.com/privacy

This plugin will not make any API calls unless an API key has been entered in the settings. Images are only sent to the PuffPix API when compression is explicitly triggered (on upload if auto-compress is enabled, or manually via the media library or bulk compress page).

PuffPix Compress

Automatically compress and optimize images on upload. Bulk-optimize your entire media library. Smaller files, faster site — no quality loss.

Akukita Image Optimizer & WebP Converter speeds up your WordPress site by automatically compressing every image you upload and creating a modern WebP copy — all done on your own server. Your media is never sent to an external service, so it stays private and you are never rate-limited or charged per image.
On top of optimisation, it does two things most image plugins don’t: it finds unused images sitting in your media library, and it catches uploads from form plugins (Gravity Forms, WPForms, Formidable) that normally bypass WordPress and never get optimised.
<h4>Why this plugin?</h4>
Large images are the number one cause of slow WordPress sites, and over time the media library fills up with images nobody uses any more. This plugin tackles both: it optimises new uploads the moment they arrive, and it shows you the clutter you can safely review and clean up.
<h4>Free features</h4>
<ul>
<li>Find unused images — scans your media library for images not referenced anywhere and lists them with their wasted disk space, so you can review what to remove. Detection is conservative and review-only; nothing is ever deleted automatically.</li>
<li>Form-plugin integrations — automatically optimises images uploaded through Gravity Forms, WPForms and Formidable Forms, which normally bypass the WordPress media flow and never get compressed.</li>
<li>Scan Uploads folder — finds JPEG/PNG images that exist on disk but were never optimised (placed there by migrations, FTP, or other plugins), and lets you optimise them all in one click.</li>
<li>Automatic compression on upload for JPEG and PNG, at a quality level you control.</li>
<li>WebP conversion — a <code>.webp</code> copy is generated for each image and its thumbnails.</li>
<li>Automatic WebP delivery — visitors whose browsers support WebP are served the smaller file automatically; everyone else gets the original.</li>
<li>EXIF / GPS metadata stripping for smaller files and better privacy.</li>
<li>100% local processing using your server’s Imagick or GD library. No accounts, no API keys, no per-image limits.</li>
<li>Savings dashboard showing how many images were optimised and how much space you saved.</li>
<li>Translation ready and fully internationalised.</li>
</ul>
<h4>Premium features</h4>
A separate Premium add-on unlocks:
<ul>
<li>Safe bulk deletion of unused images, with a backup so you can undo.</li>
<li>Bulk optimisation of your entire existing media library, processed in the background.</li>
<li>AVIF conversion for even smaller files than WebP.</li>
<li>Scheduled re-optimisation and per-folder rules.</li>
<li>One-click restore of original files.</li>
<li>Priority email support.</li>
</ul>
Premium is optional. The free plugin is fully functional on its own.
<h4>Privacy</h4>
This plugin does not send your images, or any personal data, to any external server. All optimisation happens on your hosting. It does not phone home and sets no cookies.
