Enfants Img Performer

Enfants Img Performer converts your WordPress images to WebP automatically on upload – 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

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

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.
