Описание
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)
External Services
This plugin can optionally send anonymous usage data to an external service operated by Enfants Terribles digital GmbH.
CO₂ Statistics (opt-in, disabled by default)
When you enable «Global sustainability stats» in the plugin settings, the plugin sends the following data once per day to our EU-based server:
- An anonymous random site ID (UUID v4, generated locally, no personal data)
- Total bytes saved through WebP conversion
No images, no IP addresses, no domain names and no personal data are transmitted. The anonymous site ID cannot be traced back to you or your website.
This data is used solely to display a global CO₂ savings counter on the plugin website.

Часто задаваемые вопросы
-
Does this plugin send images to an external server?
-
No. All conversions happen locally using PHP’s GD library (with Imagick as fallback). Your images never leave your server.
-
Is there a monthly limit?
-
No. Img Performer converts unlimited images for free. There are no quotas, no credits and no subscription required for the basics.
-
Which image formats are supported?
-
JPEG and PNG are converted to WebP. Other formats (GIF, SVG, WebP) are skipped. AVIF conversion is available via the separately installable Enfants Img Performer PRO plugin.
-
What happens if my server doesn’t support WebP?
-
The plugin checks for WebP support automatically. If not available, conversion is silently skipped and the original image is served. No errors, no broken images.
-
Does it work with page builders like Elementor or Divi?
-
It works well with Gutenberg and the classic editor. Page builders like Elementor or Divi sometimes use their own image rendering pipelines – a quick test on your setup is recommended.
-
Does it work with lazy-load plugins?
-
Yes. Img Performer replaces URLs in
data-src,data-full,data-largeanddata-lazy-srcattributes used by popular lazy-load plugins like WP Rocket and Jetpack. -
Does it replace images in lightboxes?
-
Yes. When you enable «Expand on click» in Gutenberg, the lightbox link (
href) is also rewritten to serve WebP or AVIF. -
Does the AI image labeling send any data externally?
-
No. Detection and labeling both run entirely locally on your own server, the same as WebP conversion. No image data, API keys or cloud connection involved.
-
Will the AI labeling detect every AI-generated image?
-
Only if the image itself carries embedded provenance data (such as a C2PA manifest) from the tool that generated it. Not every AI tool embeds this yet, and re-saving, editing or screenshotting an image removes it. Images without a usable signal are marked «Unknown» so you can review and correct them manually.
