No. The plugin updates WordPress Media Library references so your posts/pages continue working normally. ### Can I bulk optimize my Media Library? Yes! You can optimize your entire Media Library in safe batches with a progress bar. ### What happens if optimization fails? Nish Image Optimizer automatically falls back to a supported format (e.g., JPEG). ## 使用者評論 ![](https://secure.gravatar.com/avatar/cd49088cf4549350f20051b4b9a0b5d06101117377ac433bbbdc61c49a2c56a3? s=60&d=retro&r=g) ### 󠀁[Amazing Image Optimizer – Free & Pro](https://wordpress.org/support/topic/amazing-image-optimizer-free-pro/)󠁿 [mizanckp](https://profiles.wordpress.org/mizanckp/) 2025 年 9 月 22 日 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).
