Enfants Img Performer

Enfants Img Performer converts your WordPress images to WebP automatically on upload and detects AI-generated images for EU AI Act Art. 50 compliance – without sending a single byte to an external service. Everything runs on your own server, without limits. The separately available Enfants Img Performer PRO plugin unlocks AVIF conversion, bulk optimization and AI-powered alt text generation. Why Img Performer? Most image optimization plugins send your images to a third-party cloud service for processing – often with monthly quotas and accounts required. Img Performer is different: it uses PHP's built-in GD library (with Imagick as fallback) to convert images locally. Your images never leave your server. No account needed. No monthly limit. What it does

• Converts JPEG and PNG uploads to WebP automatically – unlimited, free
• Converts all registered image sizes (thumbnail, medium, large, custom)
• Rewrites src, srcset, href (lightbox) and lazy-load attributes in the frontend
• Deletes WebP files when the original image is deleted
• Logs all conversions for transparency
• Configurable quality setting (1–100, default 85)
• CO₂ savings tracker with optional anonymous global statistics
• Detects AI-generated images on upload and labels them for EU AI Act Art. 50 compliance – see below

The separately available Enfants Img Performer PRO plugin (installed alongside this plugin) adds:

• AVIF conversion – up to 50% smaller than WebP
• Bulk Converter – convert your entire media library in one click
• AI Alt Text Generator – WCAG-compliant alt texts via Mistral, Claude or OpenAI
• AI labeling in Alt-Text – optionally append a disclosure note to the alt text of AI-classified images

EU AI Act Art. 50: AI image labeling From August 2, 2026, AI-generated images published on a website must carry machine-readable labeling under Article 50 of the EU AI Act. WordPress itself strips this information the moment it generates thumbnails on upload (WordPress/ai issue #421, unresolved) – Img Performer works around that:

• Detects AI provenance in newly uploaded images (based on embedded metadata such as C2PA manifests, where present)
• Writes its own hosting-independent labeling into the original and every generated image size – no Imagick required
• Shows a visible "AI-generated" badge on the frontend, toggleable
• Lets you manually correct the automatic classification directly in the Media Library
• Shows an "AI Labeling" status column and Alt-Text presence indicator in the Media Library list view, with a "Needs review" filter for unclassified images
• Only applies to new uploads – your existing media library is not scanned or changed retroactively

The separately available PRO plugin additionally lets you append a disclosure note to the image's alt text itself when it's classified as AI-generated (optional, per image). This labeling is based on the IPTC "Digital Source Type" standard field and meets the technology-neutral requirements from the EU AI Act Code of Practice. It is not a cryptographically signed C2PA manifest – producing one would require certification through the official C2PA Conformance Programme, a separate process this plugin does not perform. GDPR / DSGVO Enfants Img Performer processes all images exclusively on your own server. No image data, IP addresses or personal information is transferred to external services. No API keys required. The only optional external connection is the anonymous CO₂ statistics feature (opt-in, disabled by default). When enabled, it sends only total bytes saved to our EU-based server – no IP address, no domain, no personal data. Requirements

• WordPress 6.0 or higher
• PHP 7.4 or higher
• GD extension with WebP support (imagewebp)

0.3.3

• Fix: AI label wasn't detected on themes that render images manually without WordPress's own wp-image-{ID} class (e.g. custom Blade/Tailwind templates) – detection now also matches by image URL, with fallbacks for resized filenames, for files renamed by the plugin's own WebP conversion, for WebP size variants generated independently by WordPress core, and for WordPress's own "-scaled" suffix on auto-downscaled originals
• Fix: Badge appeared below the image instead of on top of it on themes that set a vertical margin on images (e.g. Tailwind Typography)
• Fix: Labeled images rendered narrower than unlabeled ones when image width was set via a CSS class (e.g. Tailwind's w-full) instead of inline style

0.3.2

• Fix: AI-labeling badge broke the Gutenberg Gallery block's "Crop images to fit" option and images with a fixed height (e.g. Featured Images using object-fit: cover) – images fell back to their natural aspect ratio instead of cropping
• Fix: Small gap below labeled images caused by a missing vertical-align on the badge wrapper
• Fix: Dashboard "Review markings" button now links directly to the filtered Media Library view instead of the settings tab
• Fix: "WebP quality" label corrected to "Quality", since the setting also applies to AVIF (PRO)

0.3.1

• Fix: Long filenames no longer break the History table layout (AI Labeling and File Optimization tabs) – truncated with an ellipsis, full name shown on hover
• Fix: AI-labeling badge position was incorrect on images rendered without the theme's own display:block reset (e.g. ACF image fields) – now positioned consistently everywhere

0.3.0

• New: AI image labeling for EU AI Act Art. 50 compliance – detects AI-generated images on upload and writes hosting-independent labeling into every generated image size
• New: Visible "AI-generated" frontend badge, toggleable
• New: Manual correction control in the Media Library attachment details
• New: "Needs review" filter and status columns (AI Labeling, Alt-Text) in the Media Library list view
• New: Searchable, paginated history in Settings → AI Labeling
• Applies to new uploads only – existing media library images are not scanned or changed retroactively

0.2.2

• Renamed internal prefix from IMP to EIMP (4+ characters) to comply with WordPress.org plugin review guidelines

0.2.0

• PRO: Bulk Converter – converts entire media library to WebP/AVIF including all thumbnail sizes
• PRO: Background Queue via WP-Cron for batch processing without PHP timeout risk
• PRO: AI Alt Text Generator – generates alt text, caption and description on upload (Mistral, Claude, OpenAI)
• PRO: Bulk AI queue fills missing alt texts, captions and descriptions for all existing images
• Fixed: Bulk conversion now correctly creates WebP and AVIF for all registered image sizes
