Nish Image Optimizer

Nish Image Optimizer is a fast and simple WordPress plugin designed to make your website lighter and faster.
It automatically compresses and converts your images into modern formats like WebP and AVIF, while also supporting JPEG and PNG.

By optimizing images directly inside WordPress, you can dramatically improve page speed, Core Web Vitals, and SEO rankings — without relying on third-party APIs or external services. Nish Image Optimizer runs 100% locally on your server using WordPress’ built-in image libraries (GD/Imagick).
