It’s dedicated to compressing and resizing images to accelerate website loading times while preserving image quality. Smush is renowned for its automatic image optimization capability, proving to be very useful for users with minimal technical knowledge.

Caching and Performance Optimization

WP Rocket excels in caching with its robust page caching mechanism, guaranteeing quicker loading times for both logged-in and non-logged-in users.
