FAQ
Will this break my site?
Risky features (minification) are OFF by default. Enable them one at a time and test.
Does WebP conversion affect originals?
No. Original files are kept. WebP versions are stored alongside and can be removed anytime.
Does it work with WooCommerce?
Yes. Free includes lazy loading and cleanup. PRO adds WooCommerce-specific optimizations.
Does it conflict with caching plugins?
Free does not cache pages. PRO page caching auto-detects conflicts and disables itself.
