Amazing Image Optimizer – Free & Pro

I’ve been using Nish Image Optimizer for a while and I’m really impressed. The free version is already powerful – it lets you optimize JPEG, PNG, and WebP images directly on upload, adjust quality settings, and even run bulk optimization across the media library. It’s lightweight, easy to set up, and works out of the box without any complicated configuration.

When I upgraded to the Pro version, it got even better. AVIF support, extra controls, and more flexibility gave me noticeably smaller file sizes without losing quality. The upgrade process through Freemius was smooth, and the extra features are definitely worth it for anyone serious about performance and SEO.

Overall, this plugin has helped me improve site speed, reduce storage, and deliver images in modern formats. The developer is responsive and keeps improving it. Highly recommended for both casual users (the free version) and professionals (the Pro upgrade).
