https:\/\/fluxplugins.com\/privacy-policy\/<\/a><\/p>\n\nKey points:<\/strong>\n* Local processing by default - no external data sharing\n* Email collection for marketing purposes only with opt-in consent\n* Account ID (UUID) generation: The plugin generates a unique identifier (UUID) locally on your server for service identification purposes. This UUID is stored only in your WordPress database and is used to match webhook requests and license validation. The UUID is NOT used for user tracking or analytics. On uninstall, plugin-specific options are removed while the shared suite account ID (flux-plugins_account_id<\/code>) is preserved for other Flux Suite plugins. The UUID may be transmitted during license activation\/validation, compatibility checks, and when optional cloud processing is enabled.\n* Full compliance with WordPress.org guidelines and privacy regulations<\/p>\n\n\n\nDoes this plugin work with any WordPress theme?<\/h3><\/dt>\nYes, Flux Media Optimizer works with any WordPress theme. It integrates seamlessly with WordPress's image rendering system and doesn't require any theme modifications. The plugin hooks into WordPress's core image functions, so it works automatically with any theme that uses standard WordPress image functions.<\/p><\/dd>\n
Will this break my existing images or videos?<\/h3><\/dt>\nNo, Flux Media Optimizer creates new optimized versions while keeping your original media files as fallbacks. Your original images and videos remain untouched and are always available as a fallback for browsers that don't support modern formats or if you need to restore the originals.<\/p><\/dd>\n
External services<\/h3><\/dt>\nThis plugin can optionally use the Flux Plugins API for license validation and for optional<\/strong> cloud media processing \/ CDN delivery. Local image and video optimization works without any external service, license, or outbound media upload.<\/p>\n\n\n- Service: Flux Plugins API. Default base URL:
https:\/\/api.fluxplugins.com<\/code>. Override with FLUX_MEDIA_OPTIMIZER_EXTERNAL_SERVICE_URL<\/code> and\/or FLUX_PLUGINS_COMMON_EXTERNAL_SERVICE_URL<\/code> (common wins when both are set; otherwise the plugin override populates common). Timeout: FLUX_MEDIA_OPTIMIZER_EXTERNAL_SERVICE_TIMEOUT<\/code> \/ FLUX_PLUGINS_COMMON_EXTERNAL_SERVICE_TIMEOUT<\/code>.<\/li>\n- When requests occur: when a license key is activated or validated; when compatibility checks run via the shared library; and when you explicitly enable optional Flux cloud processing with a valid license (uploads and conversion jobs, webhook callbacks, CDN URLs).<\/li>\n
- 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.<\/li>\n
- Optional cloud processing and CDN are opt-in<\/strong>. They require enabling the setting and a valid license. You can turn them off at any time to return to local-only processing.<\/li>\n<\/ul>\n\n
Optional newsletter subscription (settings screen):<\/p>\n\n
\n- Service endpoint:
https:\/\/fluxplugins.com\/wp-admin\/admin-ajax.php?action=tnp&na=s<\/code><\/li>\n- When: only when an administrator submits the Stay Updated form with email and privacy acceptance<\/li>\n

Does this work with existing images and videos?<\/h3><\/dt>\nYes! Flux Media Optimizer can bulk process all your existing images and videos. Just go to the settings page and enable bulk conversion to optimize your entire media library. However, some pages utilizing the media files may require updating, as they may have directly embedded the non-optimized format.<\/p><\/dd>\n
Can I see which media files are optimized?<\/h3><\/dt>\nYes. The Media Library list view includes an Optimization column with status badges and a filter dropdown for Optimized, Pending, Failed, Disabled, and Unprocessed items. Local optimization status is always visible; cloud Pending\/Failed states appear when optional Flux cloud processing is enabled.<\/p><\/dd>\n
What is the CDN feature?<\/h3><\/dt>\nThe CDN (Content Delivery Network) feature is an optional service that stores your media files on a global network of servers. This ensures your images, videos and other media files load instantly for visitors worldwide, regardless of their location. The CDN feature requires explicit opt-in and a license key - all core functionality works locally without it.<\/p><\/dd>\n
How much space will I save?<\/h3><\/dt>\nCurrently the original files are still stored on your system for fallback, so there is no storage benefit. It will optimize page load speeds and reduce the download size for your webpages. The optimized files are typically 50-70% smaller than the originals, which means faster page loads and better user experience.<\/p><\/dd>\n
What if my server doesn't support WebP or AVIF?<\/h3><\/dt>\nFlux Media Optimizer automatically detects your server's capabilities and only creates formats that are supported. If your server doesn't support modern formats, you can purchase a license to utilize the external processing and CDN service, which handles all format conversions on external servers.<\/p><\/dd>\n
Does this work with animated GIFs?<\/h3><\/dt>\nYes! Flux Media Optimizer fully supports both static and animated GIFs. When Imagick is available, animated GIFs are converted while preserving their animation. The plugin automatically detects whether a GIF is animated and handles it appropriately.<\/p><\/dd>\n
Does this work with HEIC\/HEIF (including iPhone photos)?<\/h3><\/dt>\nYes, when server libraries can decode the source file. Static HEIC\/HEIF requires Imagick with HEIC\/HEIF decode support; libheif 1.18.2+ is recommended for modern iOS HDR\/gain-map photos. Files convert to WebP and\/or AVIF according to Settings. Rare animated HEIF sequences (msf1<\/code>) preserve animation in WebP when WebP is enabled and compatible FFmpeg support is available; otherwise the plugin creates static first-frame output in enabled formats. AVIF output is static. Apple Live Photos (HEIC + paired MOV) are not supported as combined assets. Undecodable HEIC\/HEIF files appear as Failed in Media Library.<\/p><\/dd>\nWill this slow down my site?<\/h3><\/dt>\nNo, Flux Media Optimizer is designed to improve your site's performance, not slow it down. Media optimization happens in the background, and the plugin uses efficient caching to minimize any impact. However, compressing images and especially videos can be CPU intensive during conversion operations. With the optional license service, all compression operations are done on our remote servers, reducing your server load. Your pages will load faster as optimized media is served efficiently.<\/p><\/dd>\n
Can I control the quality of the optimized images?<\/h3><\/dt>\nYes, Flux Media Optimizer provides comprehensive quality control settings. You can adjust the quality settings for WebP and AVIF formats separately, allowing you to balance file size and image quality according to your needs.<\/p><\/dd>\n
Does this work with WooCommerce?<\/h3><\/dt>\nYes, Flux Media Optimizer works with WooCommerce and automatically optimizes product images. The plugin integrates with WordPress's media library, so all images uploaded through WooCommerce are automatically optimized.<\/p><\/dd>\n
What video formats are supported?<\/h3><\/dt>\nFlux Media Optimizer supports video optimization with FFmpeg. You can convert videos to AV1 (stored in an MP4 container) and WebM with configurable bitrate and quality settings. The plugin processes videos in the background to reduce impact on your site's performance.<\/p><\/dd>\n\n<\/dl>\n\n\n
4.3.0<\/h4>\n\n\n- Feature: Local HEIC\/HEIF conversion with Imagick decode (libheif 1.18.2+ recommended for modern iOS photos), optional animated HEIF-to-WebP via FFmpeg, and separate HEIC capability reporting.<\/li>\n
- Feature: Unified Action Scheduler retries for local and cloud failures (3 automatic attempts with progressive backoff), with processing routed by current license\/settings and Flux logging on failures.<\/li>\n
- Feature: Redesigned attachment details panel with async REST loading, compact skeleton placeholder, MUI Grid responsive layout that stays within the WordPress container, size accordion, format URLs, and a license-aware CDN upsell.<\/li>\n
- Feature: Attachment details poll every 15 seconds while Pending (including locally deferred video conversions) and refresh Convert\/Disable\/Enable actions in place without a full page reload.<\/li>\n
- Feature: Attachment details show only formats enabled and supported by the active media converter (WebP\/AVIF for images, AV1\/WebM for videos), with per-size savings badges compared to the same-size original.<\/li>\n
- Feature: Attachment details and conversion controls use WordPress
edit_post<\/code> attachment capabilities.<\/li>\n- Fix: External processing activation requires a valid license; uninstall removes the correct option keys while preserving shared suite account ID; safer database table-drop SQL; external operations builder hardening.<\/li>\n
- Fix: Image conversion publishes files and metadata\/statistics together (no partial meta on multi-size failure); skipped retries no longer consume the retry budget; plugin\/common external API URL constants stay aligned.<\/li>\n<\/ul>\n\n

- Security: Register webhook route only when external service is enabled and license is valid.<\/li>\n
- Fix: Remove duplicate admin AJAX handler registration for attachment actions.<\/li>\n
- Security: Avoid exposing raw exception messages in plugin REST error responses.<\/li>\n
