ImOptimizer – Optimize Images
·
Boost site speed by automatically converting uploads to WebP. Features smart memory protection, detailed logging, and zero API dependencies.
ImOptimizer – Optimize Images is a safe, lightweight way to serve next-gen images on WordPress by converting uploads to WebP.
Most optimization plugins either rely on external APIs or risk server crashes by processing images without checking memory limits. ImOptimizer runs fully on your server using the native PHP GD library and includes a Smart Memory Guard that estimates RAM usage before converting—helping prevent memory exhaustion.
🚀 Why ImOptimizer?
- Boost Core Web Vitals: WebP images reduce page weight and speed up loading.
- Zero API Fees: No subscriptions, no credits, no data sharing. Runs locally.
- Server Safety First: Skips risky conversions on low memory and detects conflicts (Smush/EWWW/ShortPixel, etc.).
- Set & Forget: Auto-converts JPG/JPEG/PNG at upload time.
⚡ Feature Highlights
- Smart Conversion: Converts the main image AND generated thumbnails (Media Library, WooCommerce, etc.).
- Self-Cleaning Logs: Optional logging with retention cleanup (Cron).
- MIME Sync: Updates WordPress metadata so
.webpis recognized correctly. - Privacy Focused: Your images never leave your server.
