Descrição
Auto WebP Converter & Logger is the smartest, safest way to serve next-gen images on WordPress.
Most optimization plugins slow down your site with external API calls or crash your server by processing huge files. Auto WebP Converter is different. It runs entirely on your server using the native PHP GD library, featuring a unique Smart Memory Guard that calculates available RAM before processing to prevent crashes.
🚀 Why Auto WebP Converter?
- Boost Core Web Vitals: Serving WebP images significantly reduces page load size.
- Zero API Fees: No subscriptions, no credits, no data sharing. It’s 100% free.
- Server Safety First: Detects low memory and conflicting plugins (like Smush/EWWW) to prevent errors.
- Set & Forget: Auto-converts JPGs and PNGs immediately upon upload.
⚡ Feature Highlights
- Smart Conversion: Converts the main image AND all thumbnails (Media Library, WooCommerce, etc.).
- Self-Cleaning Logs: Detailed conversion history with auto-delete (Cron) to keep your database clean.
- MIME Sync: Automatically updates WordPress metadata so browsers recognize the
.webpformat. - Privacy Focused: Your images never leave your server.
