Frequently Asked Questions

Common questions about Flux Media Optimizer – Image & Video Optimization by Flux Plugins

Yes. It hooks into WordPress core media/image APIs, so themes and plugins that use standard WordPress image functions work without theme changes.

No. Originals stay on your server as fallbacks. The plugin creates optimized copies (or cloud/CDN URLs when that service is enabled). You can keep serving or restoring from the originals.

No. Optimized versions are added alongside originals. Untouched originals remain available for unsupported browsers or if you disable optimization for a file.

Download / page weight: Optimized outputs are commonly 50–70% smaller to transfer than the source files. Format-level ranges are summarized under “File size savings” in the Description. Overview and attachment panels show your byte totals and percentages. Disk space: Originals are kept, so server storage is not reduced by default. Savings are about faster pages and less bandwidth for visitors — not freeing upload-directory capacity.

Conversion (especially video) is CPU-intensive while jobs run. Work is queued in the background so front-end browsing stays responsive, but a busy bulk run can still load the server. If CPU is limited, enable optional Flux Suite cloud processing so heavy conversion runs off-site, or process the library in smaller batches.

Local video optimization and some animated HEIF → animated WebP paths need FFmpeg on the server. Image-only WebP/AVIF conversion uses GD/Imagick and does not require FFmpeg. Overview shows whether FFmpeg is detected. Without FFmpeg, use Flux Suite cloud processing for video (when licensed and enabled), or stick to images locally.

Local AVIF output needs a library stack that can encode AVIF (typically a capable Imagick/libheif build). The plugin detects capabilities and only offers formats your server can produce. If local AVIF is missing, keep WebP local, or use optional Flux Suite cloud processing to generate formats on Flux infrastructure.

Default: processing is local — media files are not uploaded to Flux for optimization. Optional cloud/CDN: only after you activate a license and enable the external service. Then media (and related metadata) may be sent for processing and CDN delivery. License validation and compatibility checks may send limited site/plugin metadata (see External services below). Newsletter signup sends email only if an admin opts in on the settings form. Full policy: https://fluxplugins.com/privacy-policy/

Yes. Disable external/cloud processing in plugin settings anytime to return to local-only optimization; new work stays on your server. CDN URLs stop being used for new delivery according to your settings once cloud is off (existing CDN-hosted assets may remain on Flux until cleaned up per service terms). Billing or license cancellation for a paid Flux Suite subscription is managed on fluxplugins.com (the plugin cannot cancel a store subscription by itself).

With a valid license and cloud/CDN enabled, optimized (and optionally other) media can be stored on Flux's global CDN and served over HTTPS from allowlisted hosts. Core local optimization does not require the CDN. CDN is opt-in, intended for faster worldwide delivery and to pair with offloaded processing — not a replacement for keeping originals locally unless you choose that workflow. External services This plugin can optionally use the Flux Plugins API for license validation and for optional cloud media processing / CDN delivery. Local image and video optimization works without any external service, license, or outbound media upload. Service: Flux Plugins API. Default base URL: https://api.fluxplugins.com. When requests occur: license activate/validate; shared-library compatibility checks; and when you explicitly enable optional Flux cloud processing with a valid license (uploads, conversion jobs, webhooks, CDN URLs). Data sent may include: license key (when provided), account ID (UUID), site URL/domain, plugin version, and media files/metadata only when optional cloud processing is enabled. Optional cloud processing and CDN are opt-in. Enable the setting with a valid license; turn off anytime for local-only processing.
