Lightweight WordPress image optimizer. Compress JPEG, PNG, WebP, and AVIF automatically for faster websites.

== Description ==

**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).

### 🚀 Key Features
- ✅ **Automatic Optimization on Upload** – new images are optimized instantly.  
- ✅ **Bulk Optimization** – optimize your entire Media Library with a single click.  
- ✅ **Multiple Formats** – WebP, AVIF, JPEG, PNG.  
- ✅ **Skip Already Optimized Images** – saves time and resources.  
- ✅ **Minimum File Size Skip** – ignore small icons or logos.  
- ✅ **Fallback Detection** – if AVIF/WebP isn’t supported, it falls back to JPEG/PNG automatically.  
- ✅ **WP-CLI Support** – for developers who want command-line optimization.  
- ✅ **Lightweight & Fast** – no external API calls, no credits, no monthly limits.  
- 🔑 **Pro Features** – per-image re-optimization, advanced PNG → WebP/AVIF handling, and more.

== Frequently Asked Questions ==

= Does this plugin replace my original images? =  
Yes. Nish Image Optimizer overwrites originals with optimized versions by default to save disk space.  

= Can I convert to WebP or AVIF? =  
Yes, if your hosting server supports GD/Imagick with WebP/AVIF enabled. Otherwise, the plugin will automatically fall back to JPEG/PNG.  

= Do I need credits or an external API? =  
No. The plugin runs **100% locally** inside WordPress. No external services, no hidden costs.  

= Will this break my existing images or links? =  
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).
