It compresses images automatically on upload, batch-converts your entire media library to WebP and AVIF, configures Apache to serve next-gen formats automatically, and scans your site for common technical SEO issues. #### Features **Auto-Compress on Upload** Every JPG/PNG above a configurable size threshold is automatically scaled and compressed before WordPress generates its thumbnail sizes. No extra steps needed. **Bulk Compression** Run a background batch job to compress all existing images in your media library. Progress is tracked and the job runs asynchronously — it won’t block your browser. **WebP Converter** Batch-convert all JPG/PNG/GIF files in your uploads directory to WebP format. Runs in the background using WP-Cron or a loopback HTTP request. Supports both Imagick and GD libraries. **AVIF Converter** Convert images to AVIF — the next-generation format that can be 30–50% smaller than WebP. Requires Imagick 7+ with AVIF support or PHP 8.1+ with GD `imageavif()`. The plugin detects support automatically and warns you if AVIF is unavailable on your server. **Apache .htaccess Configuration** One click adds `mod_rewrite` rules to your `. htaccess` so Apache automatically serves `.webp` files to browsers that support them, with no code changes required in your theme. **Image Dimensions Scanner** Detects images ≥ 1600 px wide that are used in posts or as featured images. Helps you find oversized images that slow down page loads, along with their file sizes, dimensions, and WebP/AVIF conversion status. **Site Audit** Scans your site for the most common technical issues: missing alt text, oversized images, missing SSL, outdated plugins, pages without Open Graph tags, and more. Results include actionable recommendations. **Dashboard Widget** A compact stats panel on the WordPress admin dashboard showing compression savings, WebP/AVIF conversion counts, and a link to the optimizer. #### Requirements * PHP 8.0+, WordPress 6.0+ * GD or Imagick PHP extension (for WebP/compression) * Imagick 7+ with AVIF or PHP 8.1+ GD (for AVIF conversion) * Apache + `mod_rewrite` (for automatic WebP serving via `.htaccess`) #### Privacy This plugin does not collect any personal data and does not make any external HTTP requests. ## Screenshots * [[ * Main dashboard — image health score, library stats, and optimization overview. * [[ * WebP Converter tab — batch conversion controls, server library status, and progress tracking. * [[ * Site Audit tab — one-click free scan for performance, SEO, and security issues. ## Instalacija 1. Upload the `mits-image-optimizer` folder to `/wp-content/plugins/`. 2. Activate the plugin via **Plugins Installed Plugins**. 3. Navigate to **MITS Optimizer** in the WordPress admin sidebar. 4. (Optional) Click **Konfiguruj .htaccess** on the WebP tab to enable automatic browser- side WebP delivery. ## FAQ ### Does this plugin delete my original images? No. Original images are never deleted. WebP and AVIF files are saved alongside originals with a `.webp` or `.avif` extension (e.g. `photo.jpg` `photo.jpg.webp`). ### What happens if my server doesn’t support AVIF? The AVIF tab will display a warning with the reason (e.g. Imagick version too old, or GD `imageavif()` not available). WebP conversion and compression still work independently of AVIF support. ### Does it work with object-cache or page-cache plugins? Yes. The plugin only modifies image files in your uploads directory and your `.htaccess`. It is compatible with all major caching plugins. ### Can I run compression and WebP/AVIF conversion at the same time? It is not recommended. Run one batch job at a time to avoid server load spikes and to keep progress tracking accurate. ### Is the .htaccess change reversible? Yes. The plugin wraps its rules in clearly marked comment blocks (`# BEGIN MITS WebP` … `# END MITS WebP`). You can remove them manually or via the plugin button. ### What image formats are supported? Auto-compression and bulk compression support JPG, JPEG, PNG, and GIF. WebP and AVIF conversion support the same formats. GIF files are converted to static WebP/ AVIF (animation is not preserved). ## Reviews ![](https://secure.gravatar.com/avatar/47d3fbbacac6c1bb5a24cbbedd50749371a5d69fcd16ad90702bd2dc0d0289cd? s=60&d=retro&r=g) ### 󠀁[Does exactly what it promises](https://wordpress.org/support/topic/does-exactly-what-it-promises-38/)󠁿 [programistawp](https://profiles.wordpress.org/programistawp/) 28. maja 2026 Does exactly what it promises. Auto-compression on upload works out of the box, WebP batch conversion runs smoothly in the background without blocking the browser, and the .htaccess configuration for automatic WebP serving is a one-click setup. The Image Dimensions Scanner is a nice bonus for catching oversized images before they become a performance problem.
