File size savings (what you’ll see)

Optimized files are typically much smaller to download than the originals. That cuts page weight and helps Core Web Vitals — it is not the same as freeing disk space, because originals stay on the server as fallbacks.

Typical download-size reductions (content-dependent; your results vary):

WebP (lossy) – often about 25–34% smaller than comparable JPEG
WebP (lossless) – often about 26% smaller than comparable PNG
AVIF – often up to ~50–60% smaller than comparable JPEG or PNG
Overall library – many sites see roughly 50–70% less media transfer weight after optimization

Where the plugin shows this:

Overview – aggregate original vs optimized bytes and savings percentage
Attachment details – per-size original vs WebP/AVIF (or video formats) with savings badges
Media Library – status so you can find Optimized, Pending, and Failed items

Perfect for

Bloggers and content creators who want faster sites
E-commerce stores needing better Core Web Vitals scores
Anyone serious about website performance and SEO

Ready to improve media performance? Install Flux Media Optimizer for local image and video optimization — cloud and CDN stay optional.

Technical details and server requirements

Local libraries – Image formats depend on GD/Imagick on the server. Video and some animated pipelines need FFmpeg. The Overview page reports what your host can do.
Serving – By default the plugin replaces media URLs with optimized versions. An optional experimental hybrid <picture> mode exists in Settings (off by default).
HEIC/HEIF – Static files need Imagick HEIC decode (libheif 1.18.2+ recommended for modern iPhone HDR/gain-map photos). Rare animated HEIF sequences need FFmpeg + WebP enabled for animated WebP; otherwise first-frame static output. Apple Live Photos (HEIC + MOV) are not merged as one asset.
Cloud / CDN – Optional; requires a valid Flux Suite license, explicit enablement, and secure webhooks. Turn off anytime to return to local-only processing.

Privacy

Default Behavior:
By default, all image and video processing happens locally on your server. Your media files never leave your WordPress installation unless you explicitly opt-in to external processing services.

Optional External Service:
This plugin includes an optional external service integration that provides:
* External File Processing: Offloads heavy image and video conversion tasks to external servers, reducing load on your server
* CDN Integration: Stores all media files on a global CDN for faster delivery worldwide. Images and videos are processed and optimized, while other file types (PDFs, documents, etc.) are stored directly for CDN delivery

What Data is Sent:
When the external service is enabled (requires explicit user activation and a license key), the following data is sent to the external service:
* All media files (images, videos, PDFs, documents, etc.) that you upload
* Images and videos are processed and optimized; other file types are stored directly on the CDN
* Attachment metadata (file names, sizes, formats)
* License key for authentication
* Account ID (UUID) for service identification

When Data is Sent:
Data is only sent when:
* The external service is explicitly enabled by the user in plugin settings
* A valid license key is provided and activated
* Media files are uploaded or conversion is requested

Service Provider:
The external service is provided by Flux Plugins:
* Terms of Service: https://fluxplugins.com/terms-of-service/
* Privacy Policy: https://fluxplugins.com/privacy-policy/

Important Notes:
* External service is completely optional – all core functionality works locally without it
* External service requires explicit user consent and license activation
* You can disable external service at any time to return to local-only processing
* By default, the plugin uses local processing only
