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 
* Terms of service: https://puffpix.com/terms
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.

Kitgenix

Kitgenix Image Optimizer compresses and resizes images automatically on upload and provides bulk optimization tools for your existing media library — all powered by WordPress’s native WP_Image_Editor (GD or Imagick). No external API required.
Designed to be lightweight and modular: 
– Automatic optimization on upload 
– Configurable JPEG, WebP, and PNG quality settings 
– Max-dimension resizing (preserves aspect ratio) 
– Optional WebP conversion 
– Optional EXIF metadata stripping 
– Optional thumbnail sub-size optimization 
– Per-image status tracking with a dedicated Images tab 
– Activity log for all optimization events 
– Bulk optimization with start/stop controls
<h4>Features</h4>
<ul>
<li>Zero external dependencies — uses WordPress’s built-in WP_Image_Editor powered by GD or Imagick.</li>
<li>Auto-optimize on upload — every new image is compressed and resized the moment it enters the media library.</li>
<li>Configurable quality — set JPEG quality (1–100), WebP quality (1–100), and PNG compression level (0–9) independently.</li>
<li>Max dimension capping — set maximum width and height; images exceeding those dimensions are scaled down while preserving aspect ratio.</li>
<li>WebP conversion — optionally convert JPEG and PNG images to WebP on upload.</li>
<li>Metadata stripping — remove EXIF data to shave extra bytes off every image.</li>
<li>Thumbnail optimization — optionally optimize every registered sub-size alongside the full image.</li>
<li>Bulk optimization — the Images tab shows your 30 most recent uploads with per-image status and a bulk start/stop control that processes one image at a time without timeouts.</li>
<li>Activity log — the Log tab records every optimization and settings change with timestamps.</li>
</ul>
<h3>Quick Start</h3>
<ol>
<li>Install and activate the plugin.</li>
<li>Go to Kitgenix → Image Optimizer to configure settings.</li>
<li>Upload an image — it will be optimized automatically if “Optimize on Upload” is enabled.</li>
<li>Use the Images tab to bulk-optimize existing media.</li>
</ol>
